EN 14179-2:2005 (E) 9 As long as on the concerned construction or building site no part of the design standards1 is applicable then the current method available in the country of destination shall be applied. The manufactured or supplied thickness of heat soaked thermally toughened soda lime silicate safety glass shall conform to the ordered thickness. 4.3.2.11 Protection against noise - Direct airborne sound reduction The sound reduction indexes shall be determined in accordance with EN 12758. However, the information supplied with the incoming glass can be used as the thermal toughening and heat soaking process does not alter the values. 4.3.2.12 Energy conservation and heat retention - Thermal properties The thermal transmittance value (U-value) shall be determined by calculation in accordance with
EN 673 with:  emissivity ε : the declared value of the glass manufacturer. If the information is not available, the emissivity shall be determined in accordance with EN 12898;  nominal thickness of the glass panes.

However, the information supplied about the radiation properties of the incoming glass can be used if the thermal toughening and heat soaking process does not alter the values. 4.3.2.14 Energy conservation and heat retention - Radiation properties: Solar energy characteristics The solar energy transmittance and reflectance shall be determined in accordance with EN 410. However, the information supplied about the radiation properties of the incoming glass can be used if the thermal toughening and heat soaking process does not alter the values. 4.4 Durability When products conform to the definition of heat soaked thermally toughened soda lime silicate glass as in 4.2, then the characteristics’ performances in 4.3.2 are ensured during an economically reasonable working life. The durability of glass products, including their characteristics, is ensured by the following:  compliance with this standard;  compliance with instructions from the glass product manufacturer or supplier.
1 prEN 13474 series is currently being prepared.



EN 14179-2:2005 (E) 10 The manufacturer shall supply specific installation instructions or make reference to appropriate technical specifications. NOTE Also 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;  the quality of installation of the glass product into or onto its support. 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. 5 Evaluation of conformity 5.1 General Evaluation of conformity in accordance with this standard shall be as a result of FPC and ITT in accordance with this European Standard: Factory production control; This shall include the following: a) Inspection of samples taken at the factory in accordance with a prescribed test plan; Initial inspection of the factory and of factory production control; 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).



EN 14179-2:2005 (E) 11 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 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 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 manufacturer2; 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 European Standard (same product, same characteristic(s), same or more onerous test method, sampling method and attestation of conformity) may be taken into account.

EN 14179-2:2005 (E) 12 5.2.2 Initial type testing of heat soaked thermally toughened soda lime silicate safety glass 5.2.2.1 General Initial type testing if a product conforms to the definition of heat soaked thermally toughened soda lime silicate safety glass, shall consist of: a) mechanical strength measurement in accordance with prEN 14179-1; b) fragmentation test in accordance with prEN 14179-1. 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 European Standard. 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 are 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.
