Member State of destination.
5 Evaluation of conformity
5.1 General
Evaluation of conformity in accordance with this European Standard shall be as a result of FPC and ITT in
accordance with this document:
1) Factory production control;
This shall include the following:
a) inspection of samples taken at the factory in accordance with a prescribed test plan;
b) initial inspection of the factory and of factory production control;
c) continuous surveillance and assessment of the factory production control.
2) Initial type testing of the product.
NOTE There may be a need to involve a third party, with 1) b), 1) c), and/or 2), for the purpose of regulatory marking
(see Annex ZA).
5.2 Initial type testing of the product (see 5.1, 2))
5.2.1 General
The product’s characteristics shall be initial type tested to verify they are in conformity with the requirements.
Instead of performing any actual testing, initial type testing may make use of
 generally accepted and/or conventional and/or standardised values, mentioned in the relevant standards,
or in publications that are referred to in the relevant standards,
 standardised calculation methods and recognised calculation methods mentioned in the relevant
standards, or in publications that are referred to in the relevant standards,
 test report(s) when made available except for the characteristics listed in 5.2.2.
NOTE There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA).
When actual testing is required then the ITT-initial type testing shall be undertaken on a sample representative
of the product taken from direct production or a prototype, any plant and/or line.
Whenever a change occurs in the raw material or the production process (subject to the definition of the
family), which would change significantly one or more of the characteristics, the type tests shall be repeated
for the appropriate characteristics.
5.2.1.1 Multiple lines/sites
If a manufacturer operates one and/or more lines and/or sites, the following can reduce the requirement for
multiple Initial Type Testing (ITT):
a) the manufacturers’ technical file for a product shall specifically covers all sites and/or lines of the same
1)
manufacturer ;
b) the manufacturer shall establish a direct relationship between production control, initial type testing and
on-going internal audit testing;
c) the manufacturer has a responsible individual designated to ensure product compliance based on:
 the operation of a consistent Factory Production Control system on all applicable sites and/or lines;
 the manufacturer having obtained evidence that shows the product to be consistent, with respect to
both product characteristics and intended use characteristics;
 the manufacturer has in place an internal auditing scheme, including product consistency.
5.2.1.2 Historic data
Tests previously performed in accordance with the provisions of this document (same product, same
characteristic(s), same or more onerous test method, sampling method and attestation of conformity) may be
taken into account.
5.2.2 Initial type testing of heat soaked thermally toughened alkaline earth silicate safety glass
5.2.2.1 General
Initial type testing if a product conforms to the definition of heat soaked thermally toughened alkaline earth
silicate safety glass, shall consist of
a) mechanical strength measurement in accordance with prEN 15682-1,
b) fragmentation test in accordance with prEN 15682-1.
5.2.2.2 Test specimens
The test specimens needed for the initial type test shall be processed from float glass according to
prEN 15682-1 in accordance with this document.
The ‘simplest’ type of edge work specified in the manufacturer's production control documentation shall be
used. However, if an arrissed edge is used then all other types of edge working are deemed to satisfy.

1) The terms ‘manufacturer’ and ‘producer’ are understood as being synonyms (see CPD working document
NB-CPD/02/019 issued 24 April 2002 – page 1).
The number of test specimens is as follows:
a) for mechanical strength measurement, they are given in Table 2 for alkaline earth silicate float glass, in
Table 3 for coated alkaline earth silicate float glass and in Table 4 for enamelled alkaline earth silicate
float glass;
b) for fragmentation, 5 test specimens per thickness are required.

NOTE 1 Table 4 covers all enamelled designs and all produced thicknesses.
NOTE 2 Mechanical test undertaken with enamelled surface in tension.
NOTE Strength measurement outcomes are expressed in force per unit of area and are therefore independent of the
thickness. Hence, strength measurements may be performed on a collection of test specimens with different thicknesses.
5.2.2.3 Test results
a) When the mechanical strength is measured then no measured value shall be below that given in
prEN 15682-1:2012, 11.4. However, if one value falls below then the manufacturer shall ensure that the
results relate to a 5 % probability of breakage at the lower limit of the 95 % confidence interval.
b) In the fragmentation test, no test specimen shall exhibit a fragmentation assessment that does not meet
prEN 15682-1:2012, Clause 10.
5.2.2.4 Measurement of surface pre-stress
The manufacturer may also use surface pre-stress measurement as a means of product control. If this is done
then all test specimens shall be measured prior to testing. This will show the relationship between surface pre-
stress and mechanical strength/fragmentation.
Manufacturers with more than one production line can perform the initial type test on specimens from one line.
The outcome value of surface pre-stress measurement can then be used as reference for the other production
lines and shall be confirmed by factory production control (FPC). This may also be applicable for new
production lines.
5.2.3 Initial type testing of characteristic’s performances
For initial type testing, (see 5.2.1), of the characteristics refer to 4.3.2.
Optimising thermal toughening settings specifically for one characteristic may affect negatively the optimised
settings for a different characteristic. When performance of both characteristics will be declared, new type
testing of the affected characteristic is needed.
5.3 Factory production control and inspection of samples in accordance with a prescribed
test plan (see 5.1, 1) a))
Factory production control means the permanent internal control of production exercised by the manufacturer.
All elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic
manner in the form of written policies and procedures. This production control system documentation shall
ensure a common understanding of quality assurance and enable the achievement of the required product
characteristics and the effective operation of the production control system to be checked.
A factory production control according to Annex A satisfies to this definition.
NOTE 1 A factory production control system similar to EN ISO 9001 made product specific to this document is deemed
to satisfy the requirements of 5.3.
NOTE 2 There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA).
Annex A also summarizes the tests to be carried out by the manufacturer as part of the production control in
the factory, and as further testing of samples taken at the factory in accordance with a prescribed test plan.
If the factory production control includes the optical pre-stress measurement for control purposes, the method
shall be correlated. Therefore, prior to any initial type test on mechanical strength/fragmentation according to
5.2.2.1, all test specimens shall be measured to determine their optical pre-stress. Outcomes shall be used as
reference values during factory production control.
5.4 Initial inspection of factory and of factory production control (see 5.1, 1) b))
The initial inspection of the factory and of the factory production control shall cover the parameters listed in
Table 5.
NOTE There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA).

5.5 Continuous surveillance and assessment of the factory production control
(see 5.1, 1) c))
The continuous surveillance, assessment and approval of the factory production control shall cover the
parameters listed in Table 5.
NOTE There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA).
The frequency of production surveillance shall be twice per year for new production facilities or for facilities
that do not already have an established factory production control system in accordance with this document.
When assessment of FPC fails to identify major non-conformances during four successive assessments, the
frequency can be reduced to once a year.
When a negative result is recorded, the inspection shall be repeated within two months. The frequency of
