— assessments previously performed with the previous version of prEN 14179-2 remains valid;
— where components are used whose characteristics have already been determined by the
component manufacturer on the basis of conformity with other product standards, these
characteristics need not be re-assessed providing they remain unchanged by the manufacturing
process (see the paragraph after NOTE 1);
— durability/conformity may be assessed indirectly by controlling the production processes
according to this document.
NOTE 1 AVCP systems were called Attestation of Conformity (AoC) systems under the EU Construction
Products Directive (89/106/EEC).
Products CE marked in accordance with appropriate harmonized European specifications may be
presumed to have the performances stated with the CE marking.
NOTE 2 The assignment of tasks to the notified body(ies) and the manufacturer is shown in Tables ZA.3.1 to
ZA.3.3.
When actual testing is required then the type testing (TT) shall be undertaken on a sample
representative of the product taken from direct production or a prototype, any plant and/ or line.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for those same characteristics for all products within that same family.
Products may be grouped in different families for different characteristics.
Whenever a change occurs in the raw material or production process (subject to the definition of a
family), which would change significantly one or more of the characteristics, the type tests shall be
repeated for the appropriate characteristic(s).
5.2.2 Type testing of characteristic’s performances
All characteristics in 4.2.2 that are declared shall be subject to type tests in accordance with 5.2.1.
5.2.3 Test reports
The results of the determination of the product type shall be documented in test reports. All test reports
shall be retained by the manufacturer for at least 10 years after the last date of production of the heat
soaked thermally toughened soda lime silicate safety glass to which they relate.
5.2.4 Multiple lines/sites
If a manufacturer operates more than one line and/or site, the following can reduce the requirement for
multiple type testing (TT):
a) the manufacturer's technical file for a product shall specifically cover all applicable sites and/or
lines of the same manufacturer,
b) the manufacturer shall establish a direct relationship between production control, type testing and
on-going internal audit testing,
c) the manufacturer shall have a responsible individual designated to ensure product compliance
based on:
1) the operation of a consistent factory production control system on all applicable sites and/or
lines,

prEN 14179-2:2017 (E)
2) the manufacturer having obtained evidence that shows the product to be consistent, with
respect to both product characteristics and intended use characteristics,
3) the manufacturer has in place an internal auditing scheme, including product consistency.
5.3 Factory production control (FPC)
5.3.1 General
The manufacturer shall establish, document and maintain an FPC system to ensure that the products
placed on the market comply with the declared performance of the essential characteristics.
The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the
use of the results to control raw and other incoming materials or components, equipment, the
production process and the product.
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 factory production control system documentation shall ensure a common understanding of the
evaluation of the constancy of performance and enable the achievement of the required product
performances and the effective operation of the production control system to be checked.
5.3.2 Inspection of samples in accordance with a prescribed test plan (see 5.1, List Entry 2) a))
Factory production control shall be according to Annex A of this document.
NOTE 1 A factory production control system similar to EN ISO 9001 [7] made product specific to this document
is deemed to satisfy the requirements of this clause.
NOTE 2 The assignment of tasks to the notified body(ies) and the manufacturer is shown in Table ZA.3.1 to
ZA.3.3.
Annex A of this document also summarizes the tests that shall 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.
5.4 Initial inspection of factory and of factory production control (see 5.1, List
Entry 2) b))
Initial inspection of factory and of FPC shall be carried out when the production process has been
finalized and in operation. The factory and FPC documentation shall be assessed to verify that the
requirements of Annex A are fulfilled.
During the inspection it shall be verified:
a) that all resources necessary for the achievement of the product characteristics included in this
European Standard are in place and correctly implemented an
