SIST EN IEC 61810-7-19:2026 is the Slovenian standard for Electrical relays - Tests and Measurements - Part 7-19: Electrical endurance, published by SIST and aligned with IEC 61810-7-19. It specifies how to test relay electrical endurance under normal, overload, inductive, lamp, cable, inrush, and special-load conditions, and how to evaluate the result. It is intended for relay manufacturers, test laboratories, quality teams, and anyone qualifying relays for switching applications.
What does SIST EN IEC 61810-7-19:2026 specify?
SIST EN IEC 61810-7-19:2026 gives guidance for testing relay performance under expected transportation, storage, and operational conditions, with the focus on electrical endurance. Clause 1 states that the document is used with appropriate severities and conditions to assess how specimens perform in service.
The document is organised into five main clauses and three annexes:
- Clause 1 Scope
- Clause 2 Normative references
- Clause 3 Terms and definitions
- Clause 4 Test procedure
- Clause 5 Evaluation
- Annex A Special loads
- Annex B Inductive contact loads
- Annex T Test report
The Slovenian standard is identical to prEN IEC 61810-7-19:2023.
| Annex | What it covers |
|---|---|
| Annex A | Special loads, including dedicated device applications, motor starting, lamp loads, cable loads, inrush current loads, electronic ballast loads, and solid-state relay tests |
| Annex B | Inductive contact loads, with utilization categories and test values corresponding to IEC 60947-5-1 |
| Annex T | The test report content needed to document the test |
What are the key requirements of SIST EN IEC 61810-7-19:2026?
The core of SIST EN IEC 61810-7-19:2026 is the test procedure in Clause 4, which tells you how to set up the relay, load it, run the endurance sequence, and judge the result. In practice, this is the part that determines whether a relay design can survive the expected switching duty.
Test setup and sampling
Clause 4.2 says the test is carried out on each contact load and each contact material specified by the manufacturer. Table 1 gives the number of samples and mounting conditions for type test and sampling test. That matters because the same relay can behave differently depending on how it is mounted and which contact system is being assessed.
The preferred mounting is group mounting for the endurance sequence, unless the manufacturer specifies otherwise. For PCB relays, a PCB may be used for wiring if minimum mounting distances are maintained. The document also says the load circuit shall follow the annexed test circuit unless the manufacturer explicitly specifies a different one.
Severity levels and operating duty
Clause 4.2 defines three severity levels. Severity A treats the first malfunction as a failure, Severity B allows more malfunctions before failure is declared, and Severity C follows the manufacturer’s declared level. This gives the test user a way to match the test to the intended application risk.
Unless the manufacturer states otherwise, the endurance test is done at the upper limit of the ambient temperature range, with the relay coil energized at rated voltage or another value within the rated coil voltage or operative range. If no other value is specified, the operating rate is 360 operations per hour with duty type S6 50% and 6000 operations total. The test frequency must stay below the relay’s maximum frequency of operation from IEC 61810-7-45.
Monitoring and functional checks
Clause 4 requires the contacts to be monitored for failure to make, failure to break, and unintended bridging. For relays with a manual actuating member, the document adds a manual-operation check at least 100 times, using the maximum rated switching current at the related voltage unless the manufacturer specifies otherwise. That is important for products that may be operated both automatically and by hand.
Clause 4.3 lists the conditions that have to be stated for the test, including relay type, contact material, severity level, ambient conditions, mounting method, energization value, switching current, power factor or time constant, duty factor, protective devices, and final measurements. The final measurements may include the dielectric strength test from IEC 61810-7-4 and any other checks specified by the manufacturer.
Overload testing
Clause 4 includes an overload test for fault conditions when the manufacturer declares limiting making or breaking capacity above the rated switching current. The test uses 50 cycles for AC and DC loads unless otherwise specified, and the relay must show no malfunction. After overload testing, the same samples are used for endurance testing under the same conditions.
For DC loads, the contacts should switch at least twice their maximum rated current at maximum rated voltage unless otherwise specified. For AC loads, the contacts should switch at least twice their maximum rated current at rated voltage. The clause also notes that special loads are treated in Annex A and inductive loads in Annex B.
Evaluation after testing
Clause 5 says the relay fails if the applicable failure criterion is not met. After the electrical endurance procedure, the dielectric strength test is performed again, and contact-circuit resistance and functional tests are measured when applicable. A final visual inspection is also required to verify electrical integrity.
What terms does SIST EN IEC 61810-7-19:2026 define?
Making and breaking capacities - the greatest current a relay output circuit can make and break under specified conditions such as voltage, number of operations, power factor, and time constant.
Overload - operating conditions in an electrically undamaged circuit that cause an overcurrent. In practice, this is the fault-duty condition used to stress the relay beyond normal operation.
Utilization category - a combination of requirements that represents a characteristic group of practical applications. In this document, it helps relate relay tests to real switching duties.
Severity level - the failure criterion used in the endurance test. Severity A fails on the first malfunction, Severity B on the sixth detected malfunction or two consecutive malfunctions, and Severity C is manufacturer-defined.
Contact-circuit resistance - the resistance of the contact circuit measured after testing where applicable. It shows whether the contact path has degraded.
Who uses SIST EN IEC 61810-7-19:2026?
SIST EN IEC 61810-7-19:2026 is used by relay manufacturers, test laboratories, certification and conformity assessment bodies, and quality assurance teams. It is also relevant to buyers and engineers who need to specify endurance testing for relays used in control circuits, motor starting, lamp switching, telecom and signalling applications, and other switching duties.
The document is especially useful when relays are intended for special loads, inductive loads, inrush current loads, or high-capacity applications. It also supports users who need to document test conditions and results in a reproducible way.
What changed in SIST EN IEC 61810-7-19:2026 from the previous edition?
This document supersedes 94/851/CD and 94/913/CC. The source states that it is still under study and subject to change at the draft stage.
Which standards are used with SIST EN IEC 61810-7-19:2026?
SIST EN IEC 61810-7-19:2026 is to be used with IEC 61810-1:2015. That relationship matters because the endurance part relies on the general relay requirements in the base standard.
The normative references and companion parts named in the document are:
- IEC 60669-1:2017 - provides household and similar fixed-electrical installation requirements used in some load and application cases.
- IEC 60947-5-1:2016 - provides utilization categories and test values referenced in Annex B.
- IEC 61810-7-0:202X - provides the general testing and guidance framework used throughout the document.
- IEC 61810-7-4:202X - provides the dielectric strength test used after endurance testing.
- IEC 61810-7-6:202X - provides contact-circuit resistance or voltage drop measurement.
- IEC 61810-7-7:202X - provides functional tests used in evaluation.
- IEC 61810-7-45:202X - provides the maximum frequency of operation.
- IEC 61810-10:2019 - provides additional functional aspects and safety requirements for high-capacity relays.
- IEC 62246-1:2015 - provides the generic specification for reed switches.
What does the SIST EN IEC 61810-7-19:2026 document contain?
The document contains the test procedures, test circuits, and reporting structure needed to assess relay electrical endurance. Table 1 sets sample numbers and mounting conditions, Table 2 sets the test procedure flow, and Table 3 gives schematics for contact loading. Those tables are the practical core for planning a lab test or writing a specification.
Annex A adds detailed procedures and figures for special loads such as motor starting, resistance loads, lamp loads, cable loads, electronic ballast loads, and solid-state relay testing. It includes multiple test values tables and circuit figures so that the test lab can build the correct load and verify inrush and endurance behaviour.
Annex B provides the inductive-load test matrix, including normal and abnormal conditions, endurance testing, and contact rating equivalencies to utilization categories. Annex T defines what the test report has to record so that the test can be reproduced and reviewed later.

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.
