Overview
IEC 62759-1:2022 - Photovoltaic (PV) modules - Transportation testing - Part 1: Transportation and shipping of module package units - defines methods to simulate transportation and subsequent environmental impacts on complete packaged PV module units. This second edition (2022) is a technical revision of the 2015 edition and focuses on realistic shipping simulations for flat‑plate PV modules, allowing coordination with design‑qualification tests (e.g., IEC 61215 / IEC 61646) so a single sample set can be used for both transport and performance evaluations.
Key topics and technical requirements
- Scope and applicability: Applies to flat‑plate PV modules; can serve as a basis for CPV testing though CPV specific tests/references were cancelled in this edition.
- Test procedures: Defines sequences for:
- Random vibration testing (PSD profiles)
- Shock testing
- Subsequent environmental stress tests (thermal, humidity and other combined effects as described in clause 6.4)
- Dynamic mechanical load testing (number of cycles updated in this edition)
- Sampling, handling and measurements: Guidance on sampling, intermediate measurements and stabilization steps to detect transport‑induced damage or performance shifts.
- Pass/fail and reporting: Edition 2 adds explicit pass/fail criteria and updated reporting requirements to support decision making after testing.
- Retesting and design changes: Annex B lists design modifications triggering retests; edition 2 modifies retesting requirements.
- Notable changes from 2015 edition:
- Cancellation of CPV tests/references
- Removal of different PV module classes and minimum of 10 modules per shipping unit
- Implementation of stabilization as an intermediate measurement
- Addition of pass/fail criteria, changed retesting rules, and adjusted dynamic mechanical load cycles
Practical applications and who uses this standard
- PV module manufacturers - validate that packaging and modules survive shipping and handling without loss of performance.
- Test laboratories and certification bodies - perform standardized transport simulations to support product qualification and claims.
- Packaging designers and logistics teams - develop and qualify packaging systems and unit loads for road, rail, air and sea transport.
- Quality assurance and R&D engineers - reproduce transport stress to identify failure modes and improve module robustness.
- Project developers and EPC contractors - assess shipping risk and conditional acceptance criteria for delivered PV modules.

PHOTOVOLTAIC (PV) MODULES –
TRANSPORTATION TESTING –
Part 1: Transportation and shipping of module package units
1 Scope and object
Photovoltaic (PV) modules are electrical devices intended for continuous outdoor exposure
during their lifetime. Existing type approval standards do not consider mechanical stresses that
may occur during transportation to the PV installation destination.
This part of IEC 62759 describes methods for the simulation of transportation of complete
package units of modules and combined subsequent environmental impacts, it does however
not include pass/fail criteria. 1
This standard is designed so that its test sequence can co-ordinate with those of IEC 61215 or
IEC 61646, so that a single set of samples may be used to perform both the transportation
simulation and performance evaluation of a photovoltaic module design. This standard applies
to flat plate photovoltaic modules, but may also be used as a basis for testing of CPV modules
and assemblies. 2
A list of design modifications which require a retest is provided in Annex B.
This document applies to flat plate photovoltaic modules.

100 % functional modules without any visual or functional defects
3.8
grade B or lower PV modules
grade B or lower modules may have visual or functional defects. The modules should be
equivalent to grade A modules regarding their mass, size and mechanical behavior.
4 Sampling
As test samples for the basic transportation and shock test methods, a shipping unit of PV
modules, shall be taken at random from a production batch or batches. When the test samples
are prototypes of a new design and not from production, this fact shall be noted in the test
report. The shipping unit shall contain the usual amount number of PV modules. This test
procedure is however designed for shipping units containing at least 10 modules. For further
testing (path A and B for PV modules) at least six grade A modules are needed from the shipping
unit. 3
Further three grade A PV modules are to be taken from a separate shipping unit not undergoing
any transportation simulation.
Grade B or lower modules can be used to fill up the shipping system (uniform distribution) of
samples, completing it to a regular shipping unit. Each individual substitute shall cover the same
mass, size and bending stiffness as the modules to be tested in the subsequent environmental
impact tests.
– 8 – IEC 62759-1:2022 CMV © IEC 2022
The shipping unit shall contain at least 25 % grade A modules. If the shipping unit contains less
than 24 modules at least six grade A modules shall be provided.
In case of horizontal shipping the bottom and the top of the shipping unit shall be made up with
grade A modules and in case of vertical shipping the outer modules of the shipping unit shall
be made up with grade A modules.
Use the regular shipment packaging materials with the modules, as marketed and designed by
the manufacturer.
The modules shall have been manufactured from specified materials and components in
accordance with the relevant drawings and process sheets and shall have been subjected to
the manufacturer's normal inspection, quality control and production acceptance procedures.
The modules shall be complete in every detail, including a type label and shall be accompanied
by the manufacturer's handling, mounting, shipping/packaging and installation instructions,
including the information of the maximum permissible system voltage.
The test specimen of shipping unit shall be packed in accordance with the standard procedures
used to ship modules to customers.
NOTE For CPV modules the sample numbers may vary, as shipping units may be much larger.
5 Handling
The test samples shall be handled with suitable care prior to the application of the tests
described in this document. It shall should be ensured that the test samples are not exposed to
additional mechanical impacts in form of shocks, rough handling, dropping, etc.
For the transportation from the manufacturer to the test laboratory special care should be taken
to avoid any kind of damage. A special packaging concept, e.g. an additional packaging, special
transportation method, etc., may be considered for this particular shipping route (manufacturer
– test site). Testing shall be carried out without additional packaging.
6 Testing procedures
6.1 General
Performance measurements, visual inspection, insulation and wet leakage current testing shall
be performed in accordance with IEC 61215:2005 respectively IEC 61646:2008, 10.2, 10.3 and
10.15 IEC 61215-2:2021, MQT 01, MQT 02, and in accordance with IEC 61730-2:2022, MST
16 and MST 17 as relative reference initial and control measurements. Electroluminescence or
thermal images can be used to support the evaluation of the samples initial and intermediate
status (e. g. micro cracks, defects, etc.).
The initial and visual inspection in accordance with IEC 61215:2005, 10.1 or IEC 61646:2008,
10.1 for PV modules and IEC 62108:2007, 10.1 for CPV modules shall also be part of the
assessment.
Electroluminescence images according to IEC TS 60904-13 may be used to detect cracks which
are not visible at initial and intermediate status (no pass/fail criteria are specified).
The actual transportation test is shown in Figure 1 for PV modules; Figure 2 shows a possible
test sequence for CPV modules. The sequences of combined transportation stress testing and
the possible effects of these impacts on the PV modules shall detect early failures in regards
to future life time stresses.
If a manufacturer wishes to combine the testing to this standard with type approval testing,
sequence A of Figure 1 can also be used in conjunction with IEC 61215 respectively IEC 61646
testing. Combined testing will increase the risk of failure in type approval testing, as the
transportation testing will pose additional stress to the samples. 4
Sequence B of Figure 1 could be extended with the UV preconditioning test and then also be
coordinated with IEC 61215 respectively IEC 61646.
The proposed test sequence in Figure 2 for CPV modules can also be adjusted to coordinate
with IEC 62108. The sequence shall be adjusted depending on whether receivers or modules
are tested. For receivers, instead of the pre-thermal cycling and humidity freeze test, the
thermal cycling test according to IEC 62108:2007, 10.8 may be performed.
Separate modules, that have not undergone any transportation testing, are also subjected to
the stress tests in sequences A and B. Failures induced by the transportation simulation and
potentially worsen defects due to the environmental stress tests shall be identified in
comparison to the modules tested without any transportation pre-damages. These modules
shall be used to identify if defects are caused by transportation test and subsequent
environmental test, or by environmental test only.

of the PV modules and document the influence of the stress tests. The initial, intermediate and
final measurements are:
• Visual inspection according to IEC 61215:2005, IEC 61646:2008, respectively

IEC 62108, 10.5 IEC 61730-2:2022 (MST 17)
• Optionally electroluminescence (only for PV modules) or infrared imaging can be used for
analysing modules for cracked or broken solar cells, etc.
• Electroluminescence images according to IEC TS 60904-13 or alternative methods, e.g.
dark I-V, may be used to detect cracks which are not visible at initial and intermediate status
(no pass/fail criteria are specified).
NOTE While the maximum power determination is only a relative reference measurement, some PV technologies
may require preconditioning need stabilization according to their respective type approval standard to arrive at
meaningful data.
6.3 Transportation testing
6.3.1 General
Performing tests of random vibration and various shock tests on the complete package system
of modules simulates road transportation and the related mechanical impacts on shipping units
and the (C) PV modules that are contained within.
The packaged-product shall be stored at laboratory ambient temperature and humidity for 12 h
prior to starting the tests.
NOTE Sequence B of Figure 1 can be extended by the UV preconditioning test to be able to coordinate with
IEC 61215 or IEC 61646 if desired.
While the (C) PV modules are carefully unpacked, the modules shall be marked: the original
packaging situation state and the module position, e.g. vertically or horizontally stacked within
the package shipping unit shall be adequately documented.
After the initial measurements described in 6.2, the modules shall be restored to their original
packaged condition in order to perform the tests described in 6.3.2 and 6.3.3.
6.3.2 Random vibration testing
6.3.2.1 Purpose
vibration test. Truck transportation is
Transportation simulation is achieved through a random
considered to be the most severe method of long distance transportation for shipping goods.
The truck transportation test therefore covers most other means of transportation.
– 14 – IEC 62759-1:2022 CMV © IEC 2022
6.3.2.2 Apparatus
Test equipment as described in ASTM D4728:2006, Clause 5 – Apparatus shall be used.
6.3.2.3 Procedure
The transportation simulation shall be performed in accordance with ASTM D4169-16 with one
complete stack of modules:
The applied test profile shall meet the following requirements:
a) A frequency range of within 5 from 1 Hz 7 to 200 Hz.
b) A test severity not below 0,49 0,54 g 8 as described in Annex A.
RMS
c) The test duration shall last at least 180 min.
d) Excitation axis: vertical.
Following the random vibration test, a series of shock tests shall be carried out on the shipping
unit.
6.3.3 Shock testing
6.3.3.1 Incline impact test
6.3.3.1.1 Purpose
The incline impact test shall be performed to simulate stress potentially caused by forklift
transportation.
6.3.3.1.2 Apparatus
Test equipment as described in ASTM D880-92 shall be used.
6.3.3.1.3 Procedure
The procedure as described in ISTA 3E Test Block 2 shall be followed.
6.3.3.2 Rotational edge drop test
6.3.3.2.1 Purpose
A rotational edge drop test shall be performed to test the integrity of the shipping supporting
units pallet.
6.3.3.2.2 Apparatus
Test equipment as described in ISTA 3E Test Block 3 shall be used.
6.3.3.2.3 Procedure
The procedure as described in ISTA 3E Test Block 3 shall be followed.
6.3.3.3 Vertical shock test
6.3.3.3.1 Purpose
A shock test according to IEC 60068-2-27 shall be performed. This test procedure simulates
stresses as may be caused by potholes or sidewalk edges which are not covered by the random
vibration test.
6.3.3.3.2 Apparatus
Test equipment as described in IEC 60068-2-27:2008, Clause 4 shall be used.
The following deviation will be tolerated, if the applied variations are explained and clearly
documented in the report:
• Extension of the mounting table in order to fit larger package units in an appropriate way.
6.3.3.3.3 Procedure
100 half sinusoidal shocks with duration of 11 ms shall be applied vertically (z direction).
6.3.3.4 Horizontal impact test
6.3.3.4.1 Purpose
For testing the integrity of the shipping unit regarding internal displacements or displacements
of the shipping goods against the pallet, an incline impact test shall be performed in accordance
with ASTM D5277-92. This test simulates sudden deceleration and sideward acceleration in
curves during truck transportation.
6.3.3.4.2 Apparatus
Test equipment as described in ASTM D5277-92 shall be used.
6.3.3.4.3 Procedure
A test according to ASTM D5277-92 “test method for performing programmed horizontal impact
using an incline impact tester” shall be performed. The difference compared to the incline impact
test is that the shipping unit is decelerated on the transport sledge / transport vehicle.
The pallet has to be restrained, and the load on top of the pallet has to be unrestrained.
The characteristic of this impact shall be half sinusoidal shock like. The half sinus shock shall
have a deceleration of 1 g and a length of 350 ms and shall be applied on each horizontal side.
It is common to start with an initial value of 0,3 g and increase the deceleration stepwise until
the integrity of the shipping unit is damaged or the end value of 1 g is reached.
6.4 Environmental stress tests
6.4.1 PV modules
6.4.1 Path A
6.4.1.1 General
The transportation test is followed by a thermal cycling test in accordance with IEC 61215:2005
respectively IEC 61646:2008, 10.11 IEC 61215‑2:2021 MQT 11 for 200 cycles. During this
thermal cycle test no current flow is required unless this test protocol is combined with an
IEC 61215 respectively IEC 61646 type approval. Continuity of the circuit through the module
shall still be measured using a current flow of less than 0,5 % of short circuit current of the
module under test.
6.4.1.2 Sample allocation for path A
a) 1 x module (highest power loss relative to initial measurement after transport simulation);
b) 1 x module (lowest power loss relative to initial measurement after transport simulation);
c) 1 x module from separate shipping unit.
– 16 – IEC 62759-1:2022 CMV © IEC 2022
NOTE The thermal cycling test represents the worst case variability of temperature in temperate climates. In
general, PV modules are multilayer products. Each material (layer) has a different thermal expansion. This causes
stress between the layers while thermal cycling. The cells, the joints and cell/string connectors may be especially
prone to strains.
6.4.2 Path B
6.4.2.1 General
The transportation test is followed by a dynamic mechanical load test according to
IEC TS 62782 (1 000 cycles), a thermal cycling test according to IEC 61215 respectively
IEC 61646, 10.11 IEC 61215-2:2021 MQT 11 with 50 cycles and a humidity-freeze test
according to IEC 61215 respectively IEC 61646, 10.12 IEC 61215-2:2021 MQT 12 with 20
cycles. The sequence concludes with a mechanical load test according to IEC 61215
respectively IEC 61646, 10.16 MQT 16 of IEC 61215-2:2021 in upwards and downwards
direction.
The dynamic mechanical load test for photovoltaic modules is described in IEC TS 62782. The
module shall be installed according to the installation manual of the manufacturer. If different
mounting techniques are possible, the worst case mounting situation shall be applied.
6.4.2.2 Sample allocation for path B
a) 1 x module (second 9 highest power loss relative to initial measurement after transport
simulation);
b) 1 x module (second lowest power loss relative to initial measurement after transport
simulation);
c) 1 x module from separate shipping unit.
6.4.2 CPV modules and receivers
The transportation test is followed by a dynamic mechanical load test acc. to IEC 62782, a pre-
thermal cycle test and a humidity freeze test according to IEC 62108:2007, 10.8. The sequence
concludes with a mechanical load test according to IEC 62108:2007, 10.13.
The dynamic mechanical load test for photovoltaic modules is described in IEC 62782. The CPV
module shall be installed according to the installation manual of the manufacturer. If different
mounting techniques are possible, the worst case mounting situation shall be applied.
Sample allocation for CPV modules and receivers
a) 1 × module (highest power loss relative to initial measurement after transport simulation);
b) 1 × module (lowest power loss relative to initial measurement after transport simulation);
c) 1 × modules from separate shipping unit.
7 Pass criteria 10
A shipping unit design for PV modules shall be judged to have passed the qualification tests,
and therefore to be type approved, if each PV module test sample meets all the following
criteria:
a) After the complete test sequence (of path A and B), the maximum power output drop of each
module P shall be less than 5 %, referenced to the module’s initial measured power
max
output P (Lab, Initial). Each test sample shall meet the following criterion:

Test profiles
A.1 Overview
For informative purposes, the following PSD test profiles are shown and analyzed according to
the criteria defined in Clause 6.The main reference for transport testing is the PSD profile out
of the standard ASTM D4169. Other PSD profiles also fulfill the transportation testing
requirements. The relevant frequency range for examination is between 5 1 Hz and 200 Hz.
The result of the analysis is shown in Table A.1. The listed test profiles fulfill the requirements
which are defined in Clause 6. The result of the analysis is shown in Table A.1. The listed test
profiles pass the requirements defined in Clause 6.

The resonance of PV modules depends on the construction, including mass, size and stiffness.
Tests have shown that the slowest fundamental resonance of a PV module is ~ 5 Hz. Most
transportation test profiles have the majority of the energy between the frequencies of 5 1 Hz
and 200 Hz. A reasonable benchmark for different transportation test profiles for PV modules
should therefore only include vibrations between 5 1 Hz and 200 Hz.

B.1 Overview of transportation tests after modification
If PV modules have been modified in their design, as the transportation tests listed in Table B.1,
the transportation tests shall be performed.
For any change of packaging material, profile, dimensions or assembly, a complete retest has
to be evaluated. 12
No test repetition is required for thin-film specific design modifications:
– Modification to cell technology.
– Modification to interconnect material or technique.
– Modification to front contact.
– Modification to cell layout.
– Modification to back contact.
– Modification to edge deletion.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

4 Sampling
As test samples for the basic transportation and shock test methods, a shipping unit of PV
modules, shall be taken at random from a production batch or batches. When the test samples
are prototypes of a new design and not from production, this fact shall be noted in the test
report. The shipping unit shall contain the usual number of PV modules.
Further three PV modules are to be taken from a separate shipping unit not undergoing any
transportation simulation.
Use the regular shipment packaging materials with the modules, as marketed and designed by
the manufacturer.
The modules shall have been manufactured from specified materials and components in
accordance with the relevant drawings and process sheets and shall have been subjected to
the manufacturer's normal inspection, quality control and production acceptance procedures.
The modules shall be complete in every detail, including a type label and shall be accompanied
by the manufacturer's handling, mounting, shipping/packaging and installation instructions,
including the information of the maximum permissible system voltage.
The test specimen of shipping unit shall be packed in accordance with the standard procedures
used to ship modules to customers.
5 Handling
The test samples shall be handled with suitable care prior to the application of the tests
described in this document. It should be ensured that the test samples are not exposed to
additional mechanical impacts in form of shocks, rough handling, dropping, etc.
For the transportation from the manufacturer to the test laboratory special care should be taken
to avoid any kind of damage. A special packaging concept, e.g. an additional packaging, special
transportation method, etc., may be considered for this particular shipping route (manufacturer
– test site). Testing shall be carried out without additional packaging.
6 Testing procedures
6.1 General
Performance measurements, visual inspection, insulation and wet leakage current testing shall
be performed in accordance with IEC 61215-2:2021, MQT 01, MQT 02, and in accordance with
IEC 61730-2:2022, MST 16 and MST 17 as reference initial and control measurements.
Electroluminescence images according to IEC TS 60904-13 may be used to detect cracks which
are not visible at initial and intermediate status (no pass/fail criteria are specified).
The actual transportation test is shown in Figure 1. The sequences of combined transportation
stress testing and the possible effects of these impacts on the PV modules shall detect early
failures in regards to future life time stresses.
Separate modules, that have not undergone any transportation testing, are also subjected to
the stress tests in sequences A and B. These modules shall be used to identify if defects are
caused by transportation test and subsequent environmental test, or by environmental test only.

* See 6.2 for details on measurements.
Figure 1 – Test sequences for PV modules
6.2 Measurements
Each initial, intermediate and final measurement shall characterize the electrical performance
of the PV modules and document the influence of the stress tests. The initial, intermediate and
final measurements are:
• Visual inspection according to IEC 61215-2:2021 (MQT 01)
• Stabilization (optional for intermediate measurements) according to IEC 61215-2:2021
(MQT 19)
• Maximum power determination according to IEC 61215-2:2021 (MQT 02)
• Insulation test according to IEC 61730-2:2022 (MST 16)
• Continuity test of equipotential bonding according to IEC 61730-2:2021 (MST 13)
• Wet leakage current test according to IEC 61730-2:2022 (MST 17)
• Electroluminescence images according to IEC TS 60904-13 or alternative methods, e.g.
dark I-V, may be used to detect cracks which are not visible at initial and intermediate status
(no pass/fail criteria are specified).
NOTE While the maximum power determination is only a reference measurement, some PV technologies may need
stabilization according to their respective type approval standard to arrive at meaningful data.
6.3 Transportation testing
6.3.1 General
Performing tests of random vibration and various shock tests on the complete package system
of modules simulates road transportation and the related mechanical impacts on shipping units
and the PV modules that are contained within.
The packaged-product shall be stored at laboratory ambient temperature and humidity for 12 h
prior to starting the tests.
NOTE Sequence B of Figure 1 can be extended by the UV preconditioning test to be able to coordinate with
IEC 61215 if desired.
While the PV modules are carefully unpacked, the modules shall be marked: the original
packaging state and the module position, e.g. vertically or horizontally stacked within the
shipping unit shall be adequately documented.
After the initial measurements described in 6.2, the modules shall be restored to their original
packaged condition in order to perform the tests described in 6.3.2 and 6.3.3.
6.3.2 Random vibration testing
6.3.2.1 Purpose
Transportation simulation is achieved through a random vibration test. Truck transportation is
considered to be the most severe method of long distance transportation for shipping goods.
The truck transportation test therefore covers most other means of transportation.
6.3.2.2 Apparatus
Test equipment as described in ASTM D4728:2006, Clause 5 – Apparatus shall be used.
6.3.2.3 Procedure
The transportation simulation shall be performed in accordance with ASTM D4169-16 with one
complete stack of modules:
The applied test profile shall meet the following requirements:
a) A frequency range from 1 Hz to 200 Hz.
as described in Annex A.
b) A test severity not below 0,54 g
RMS
c) The test duration shall last at least 180 min.
d) Excitation axis: vertical.
Following the random vibration test, a series of shock tests shall be carried out on the shipping
unit.
– 10 – IEC 62759-1:2022 © IEC 2022
6.3.3 Shock testing
6.3.3.1 Incline impact test
6.3.3.1.1 Purpose
The incline impact test shall be performed to simulate stress potentially caused by forklift
transportation.
6.3.3.1.2 Apparatus
Test equipment as described in ASTM D880-92 shall be used.
6.3.3.1.3 Procedure
The procedure as described in ISTA 3E Test Block 2 shall be followed.
6.3.3.2 Rotational edge drop test
6.3.3.2.1 Purpose
A rotational edge drop test shall be performed to test the integrity of the shipping supporting
units pallet.
6.3.3.2.2 Apparatus
Test equipment as described in ISTA 3E Test Block 3 shall be used.
6.3.3.2.3 Procedure
The procedure as described in ISTA 3E Test Block 3 shall be followed.
6.3.3.3 Vertical shock test
6.3.3.3.1 Purpose
A shock test according to IEC 60068-2-27 shall be performed. This test procedure simulates
stresses as may be caused by potholes or sidewalk edges which are not covered by the random
vibration test.
6.3.3.3.2 Apparatus
Test equipment as described in IEC 60068-2-27:2008, Clause 4 shall be used.
The following deviation will be tolerated, if the applied variations are explained and clearly
documented in the report:
• Extension of the mounting table in order to fit larger package units in an appropriate way.
6.3.3.3.3 Procedure
100 half sinusoidal shocks with duration of 11 ms shall be applied vertically (z direction).
6.3.3.4 Horizontal impact test
6.3.3.4.1 Purpose
For testing the integrity of the shipping unit regarding internal displacements or displacements
of the shipping goods against the pallet, an incline impact test shall be performed in accordance
with ASTM D5277-92. This test simulates sudden deceleration and sideward acceleration in
curves during truck transportation.
6.3.3.4.2 Apparatus
Test equipment as described in ASTM D5277-92 shall be used.
6.3.3.4.3 Procedure
A test according to ASTM D5277-92 “test method for performing programmed horizontal impact
using an incline impact tester” shall be performed. The difference compared to the incline impact
test is that the shipping unit is decelerated on the transport sledge / transport vehicle.
The pallet has to be restrained, and the load on top of the pallet has to be unrestrained.
The characteristic of this impact shall be half sinusoidal shock like. The half sinus shock shall
have a deceleration of 1 g and a length of 350 ms and shall be applied on each horizontal side.
It is common to start with an initial value of 0,3 g and increase the deceleration stepwise until
the integrity of the shipping unit is damaged or the end value of 1 g is reached.
6.4 Environmental stress tests
6.4.1 Path A
6.4.1.1 General
The transportation test is followed by a thermal cycling test in accordance with
IEC 61215‑2:2021 MQT 11 for 200 cycles.
6.4.1.2 Sample allocation for path A
a) 1 x module (highest power loss relative to initial measurement after transport simulation);
b) 1 x module (lowest power loss relative to initial measurement after transport simulation);
c) 1 x module from separate shipping unit.
NOTE The thermal cycling test represents the worst case variability of temperature in temperate climates. In
general, PV modules are multilayer products. Each material (layer) has a different thermal expansion. This causes
stress between the layers while thermal cycling. The cells, the joints and cell/string connectors may be especially
prone to strains.
6.4.2 Path B
6.4.2.1 General
The transportation test is followed by a dynamic mechanical load test according to
IEC TS 62782 (1 000 cycles), a thermal cycling test according to IEC 61215-2:2021 MQT 11
with 50 cycles and a humidity-freeze test according to IEC 61215-2:2021 MQT 12 with 20
cycles. The sequence concludes with a mechanical load test according to MQT 16 of
IEC 61215-2:2021 in upwards and downwards direction.
The dynamic mechanical load test for photovoltaic modules is described in IEC TS 62782. The
module shall be installed according to the installation manual of the manufacturer. If different
mounting techniques are possible, the worst case mounting situation shall be applied.
6.4.2.2 Sample allocation for path B
a) 1 x module (second highest power loss relative to initial measurement after transport
simulation);
b) 1 x module (second lowest power loss relative to initial measurement after transport
simulation);
c) 1 x module from separate shipping unit.

(informative)
Test profiles
A.1 Overview
For informative purposes, the following PSD test profiles are shown and analyzed according to
the criteria defined in Clause 6.The main reference for transport testing is the PSD profile out
of the standard ASTM D4169. Other PSD profiles also fulfill the transportation testing
requirements. The relevant frequency range for examination is between 1 Hz and 200 Hz. The
result of the analysis is shown in Table A.1. The listed test profiles fulfill the requirements which
are defined in Clause 6. The result of the analysis is shown in Table A.1. The listed test profiles
pass the requirements defined in Clause 6.
Table A.1 – Severity of common transport test profiles:

Main reference: ASTM D4169 (truck medium) 0,520
ISTA 3 E 0,540
MIL STD 810G / IEC 60068-2-64 1,040
ISO 13355 0,590
The resonance of PV modules depends on the construction, including mass, size and stiffness.
Tests have shown that the slowest fundamental resonance of a PV module is ~ 5 Hz. Most
transportation test profiles have the majority of the energy between the frequencies of 1 Hz and
200 Hz. A reasonable benchmark for different transportation test profiles for PV modules should
therefore only include vibrations between 1 Hz and 200 Hz.
A.2 Data points of appropriate PSD test profiles
The following profile has been chosen for the testing of PV shipping units. Table A.2 identifies
the profile boundaries of the PSD excitation profiles analysed and shown in Table A.1 and
Figure A.1.
