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 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, 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;

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

5.2.1.2 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 thermally toughened soda lime silicate safety glass 5.2.2.1 General To establish if a product conforms to the definition of thermally toughened soda lime silicate safety glass, initial type testing shall consist of: a) mechanical strength measurement in accordance with EN 12150-1; b) fragmentation test in accordance with EN 12150-1 5.2.2.2 Test specimens The test specimens needed for the initial type test shall be processed from float glass according to EN 572-1 and EN 572-2 in accordance with this document.
The ‘simplest’ type of edge work specified in the manufacturers production control documentation shall be used. However, if an arrissed edge is used then all other types of edge working are deemed to satisfy. The number of test specimens is as follows: a) For mechanical strength measurement they are given in table 2a for float glass, table 2b for coated float glass and table 2c for enamelled float glass. b) For fragmentation 5 test specimens per thickness are required.

Note 1: This table 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, no measured value shall be below that given in Clause 9.4 of EN 12150-1:2000. 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 Clauses 8.5 and 8.7 of EN 12150-1:2000. 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 may perform the initial type test on specimens from one line. The outcome value of surface pre-stress measurement may then be used as reference for the other production lines and shall be confirmed by factory production control (FPC). This may also be applied to new production lines. 5.2.2.5 Thermally toughened patterned glass Initial type testing of thermally toughened patterned glass may not be undertaken as a result of the wide variety of patterned surfaces of patterned glass in accordance with EN 572-5. Compliance of thermally toughened patterned glass shall be ensured by the sampling during product control given Annex A – Table A.1 – 3.1.3 together with either 3.1.4.2 or 3.1.4.3. 5.2.3 Initial type testing of characteristic’s performances
All characteristics in 4.3.2 shall be subject to initial type testing in accordance with Clause 5.2.1. 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, the affected characteristic shall be subject to a further type test.

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 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. 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, 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).
