The manufacturer shall supply specific installation instructions or make reference to appropriate technical specifications. Note 1: The durability of glass products depends on:

 building and construction movements due to various actions;  building and construction vibrations due to various actions;  deflection and racking of the glass support due to various actions;  glass support design (e.g. drainage of infiltrated water in the rebate, prevention of direct contact between glass support members and glass);  accuracy of glass support and glass support member dimensions;  quality of the assembling of glass support members up to a glass support;  quality of installation of the glass support into or onto the buildings or constructions;  glass support expansion due to adsorbed moisture from the air or other sources; – quality of installation of the glass product into or onto its support. 4.4 Characteristics other than those listed in 4.2 Optical and visual characteristics shall comply with EN 572 Parts 2 to 8 Dimensional tolerances: shall comply with EN 572 Parts 2 to 8 4.5 Dangerous substances Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination.

EN 572-9:2004 (E) 10 5 Evaluation of conformity 5.1 General Evaluation of conformity in accordance with this document shall be as a result of Factory Production Control and Initial Type Testing 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 1b, 1c, 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 All the product’s characteristics shall be initial type tested to verify they are in conformity with the requirements of this document. Instead of performing any actual testing, initial type testing may make use of: – generally accepted and/or conventional and/or standardised values, in the Clause 2 referenced standards, or in publications that are referred to in these standards; – standardised calculation methods and recognised calculation methods in

Clause 2 referenced standards, or in publications that are referred to in these standards; – test report(s) on the basis of 5.2.1.2 when made available except for the characteristics listed in 5.2.2. – 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 reassessed providing they remain unchanged by the manufacturing process; – release of dangerous substances may be assessed indirectly by controlling the content of the substance concerned; – durability may be assessed indirectly by controlling the production processes according to this document; Note 1: Products CE marked in accordance with appropriate harmonised European specifications may be presumed to have the performances stated with the CE marking.

Note 2: 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 Initial Type Testing (ITT) shall be undertaken on a sample representative of the product taken from direct production or a prototype, any plant and/ or line.

EN 572-9:2004 (E) 11 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). 5.2.1.1 Multiple lines/sites If a manufacturer operates more than one line and/or site, the following can reduce the requirement for multiple Initial Type Testing (ITT): i) The manufacturers’ technical file for a product shall specifically covers all sites and/or lines of the same manufacturer1, ii) The manufacturer shall establish a direct relationship between production control, initial type testing and on-going internal audit testing, iii) The manufacturer shall have 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 if the product belongs to the group soda lime silicate glass, clear or tinted Initial type testing to establish if a product conforms to the definition of soda lime silicate glass, shall be economized as much as possible. For that purpose appropriate available test reports are equivalent to actual testing and may be used instead of actual testing. The initial type testing

concerns the product aspects as listed in Table 2.

1 The terms ‘manufacturer’ and ‘producer’ are understood as being synonyms (see CPD working document NB-CPD/02/019-issued 24 April 2002 – page1)

5.2.3 Initial type testing of characteristic’s performances

All characteristics in 4.2.2 shall be subject to initial type tests in accordance with Clause 5.2.1. 5.3 Factory production control and inspection of samples in accordance with a prescribed test plan (see 5.1, 1a and b) 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. Factory production control shall be according to Annex A of this document. 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 this clause. Note 2: There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA). Annex A of this document also summarises 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, 1c) The initial inspection of the factory and of the factory production control shall be limited to the parameters listed in Table 3 in conjunction with Annex A.

Note: There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA).
