BACKGROUND
The first document prepared by the GEPVP explained the background to compliance with the CPD1 and the
second explained the principles of evaluation of conformity2.
This document will explain the system of “Evaluation of Conformity” applicable for “laminated glass and laminated
safety glass” as laid down in EN 144493, the appropriate harmonised European Standard (hEN).
B
AUDIENCE
This part is applicable to any manufacturer of laminated glass and laminated safety glass.
C
SCOPE
This is taken from EN 14449.
“This European Standard covers the evaluation of conformity and the factory production control
of laminated glass and laminated safety glass for use in buildings.”
D
METHODOLOGY (see also summary figure 1)
This document follows the methodology given in the second document. It also follows the same referencing with
respect to “attachments”, etc.
4
This document includes explanatory information on Clause ZA.2.2 – EC Certificate and Declaration of Conformity
(see Attachment 6).
Annex ZA
As detailed in the second document the starting point for undertaking the evaluation of conformity is Table ZA.1.
This table is colour coded and each essential characteristic is numbered to line up with the corresponding table
in the second document.
The “Systems of Attestation of Conformity” for the claimed intended uses are given in Table ZA.2 of the hEN.
Details of the tasks relating to “Assignment of Evaluation of Conformity” are given in Tables ZA.3.1 to ZA.3.3 of
the hEN (see second document for explanation).
The relationship between the intended use, the applicable “Systems of Attestation of Conformity” and the roles of
the manufacturer and Notified Body(ies) is given in Figure 2. This figure is specific to conformity with EN 14449.
When a manufacturer has finalised the collection of all applicable information then he can proceed to CE Marking.
This is detailed in Clause ZA.2.2 (see Attachment 6). Based on the manufacturer’s Declaration of Conformity
is the CE Marking label. Examples of CE Marking labels for different laminated glass and laminated safety glass
products with different intended uses/characteristics and hence “Systems of Attestation of Conformity” are shown
in Figures 3, 4, 5 and 6.

Glass CANNOT be tested for resistance to fire
on its own. The tests have to be undertaken in a
glazed assembly.
The glazed assembly is regarded as a “virtual
assembly”10 and is detailed in the official
classification report.
The reaction to fire performance is influenced
by the amount of organic component, i.e. type
and thickness of interlayer, plastics glazing sheet
material.
Work is in progress on determining this
characteristic for these products on a “Classified
without further test” basis.
The present situation is that there are four
different test methods in ENV 1187. The
applicability of these tests to glass is not totally
clear.
However, before deciding to test it is paramount
that the manufacturer checks if a particular
glass product type is permitted, by national
regulations, in this application.
Laminated glass/laminated safety glass has to
be tested for this characteristic.
A product that can be classified should also be
capable of being classified as a laminated safety
glass.

This characteristic will be dependent on the
glass substrates, plastics glazing sheet materials,
interlayer types and degree of adhesion of the
interlayer(s) to the glass substrates and plastics
glazing sheet materials.
As long as on the concerned construction or
building site no part of the design standards
is applicable for the design then the current
method of determining mechanical resistance
in the country of destination shall be applied.
Note: prEN 13474 will give information on the
load carrying capacity of laminated/laminated
safety glass as well as a method for determining
the strength of laminated/laminated safety glass
constructions from first principles.
The manufactured or supplied thickness of
laminated glass or laminated safety glass
shall conform to the ordered thickness.
Supplying what was ordered, in terms of
thickness, will cover this characteristic.
prEN 13474: This standard is being drafted. It will consist of the following three parts:
- determination by calculation of the resistance to load of glass used in fenestration;
- determination by calculation of the resistance to load of glass used in common non-structural applications

EC Certificate and Declaration of Conformity
Depending upon the intended use of the product and hence the applicable “System of Attestation of
Conformity” will be the extent to which this clause applies.
1. Products with System of Attestation of Conformity – 1;
This System of Attestation of Conformity requires the involvement of a Notified Certification Body
(NCB). It is the responsibility of the NCB, when they are satisfied that compliance with the conditions
of the Annex ZA has been achieved, to produce a Certificate of Conformity (EC Certificate of
Conformity). This certificate allows the manufacturer to affix the CE Marking (see Figure 3). The detail of
what is to be included in the certificate is given in the hEN.
When the manufacturer has the Certificate of Conformity then a Declaration of Conformity
(EC Declaration of Conformity) has to be produced. The detail of what is to be included in the
declaration is given in the hEN.
2. Products with System of Attestation of Conformity – 3;
20
This System of Attestation of Conformity only requires the involvement of a Notified Body (NB) with the
Initial Type Testing of the product. When the manufacturer is satisfied that compliance with this Annex
has been achieved then a Declaration of Conformity (EC Declaration of Conformity) is prepared. This
declaration allows the manufacturer to affix the CE Marking (see Figure 5). The detail of what is to be
included in the declaration is given in the hEN.
3. Products with System of Attestation of Conformity – 4;
This System of Attestation of Conformity does not require the involvement of a Notified Body (NB).
Therefore when the manufacturer is satisfied that compliance with this Annex has been achieved
then a Declaration of Conformity (EC Declaration of Conformity) is prepared. This declaration allows
the manufacturer to affix the CE Marking (see Figure 6). The detail of what is to be included in the
declaration is given in the hEN.
Duplication of information between the certificate, where applicable, and the declaration should be
avoided. This can be done by cross-referencing between documents if one contains more information than
the other.
EC Declaration of Conformity and, if applicable, the EC Certificate of Conformity shall be presented in the
official language or languages of the Member State in which the product is to be used.

check the mechanical performance of the
laminated safety glass.
Therefore at least once per week a minimum
of 3 test specimens should be subjected to a
mechanical performance test.

Annex D (informative) – Criteria for deciding if a change within an assembly requires
a new initial type test
Clause No. Content
D.1
Explanation
General
5.2.3 discusses the requirement for initial type
testing the characteristics of the laminated
glass and laminated safety glass.
The general rules for initial type testing are
given in 5.2.112).
However, there will be circumstances when
due to changes in the material design, e.g.
change of components, changes in thickness,
alteration of the stacking order, etc., that
the “new” design is outside the product
description/product families and will require a
new initial type test. Table D.1 offers advice as
to those alterations that require consideration
of a new initial type test. The advice in
Table D.1 relates to specific intended uses/
characteristics.
Changes in the product may occur that
could result in it no longer complying with
the product description and/or specified
product family. In this case there may be
a requirement for the “new” product to be
subjected to the ITT. This need is specific to
the intended use of the product.

5.2.1 details the use of generally accepted values, calculated values etc., that should be considered before undertaking
any actual testing.
