Note: Compliance with this requirement is not possible until a version of prEN 13501-5 later than 2002 becomes available.

The manufactured or supplied thickness of coated glass shall conform to the ordered thickness. 4.3.2.10 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 may be used, as the coating process does not alter the values. 4.3.2.11 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 coating manufacturer. If the information is not available, the emissivity shall be determined in accordance with EN 12898.  nominal thickness of the glass panes 4.3.2.12 Energy conservation and heat retention - Radiation properties: Light transmittance and reflectance The light transmittance and reflectance shall be determined in accordance with EN 410. Subject to 5.2.1, the information supplied about the radiation properties of the incoming glass may be used if the coating process does not alter the values.

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;  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 document shall be as a result of Factory Production Control and Initial Type Testing in accordance with this document:

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. In addition, instead of performing any real 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 re-assessed providing they remain unchanged by the manufacturing process.  release of dangerous substances maybe assessed indirectly by controlling the amount 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. 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).

When assessment of factory production control fails to identify major non-conformances during four successive assessments the frequency can be reduced to once a year.
When a major non-conformance is recorded, the inspection shall be repeated within two months. The frequency of production surveillance shall return to, or remain at twice a year. When the repeated inspection also results in a major non-conformance, then the production shall be subject within two months to a repeated initial inspection of the factory and of the factory production control together with a surveillance inspection. When this repeated initial inspection and surveillance inspection also results in a major non-conformance, then the products are considered as no longer conforming to this document. 6 Marking and/or labelling 6.1 General All voluntary marking and/or labelling shall comply with Annex C.3.
Care shall be taken to ensure that any voluntary marking and/or labelling does not cause confusion with respect to the mandatory requirements. Note: All marking and/or labelling of product to demonstrate compliance with the regulatory requirement is detailed in Annex ZA. 6.2 Product marking There is no requirement to mark coated glass products. However, if they are processed, e.g. thermally toughened, heat strengthened etc, then they have to comply with the appropriate product standard, e.g. EN 12150, EN 1863. 6.3 Product characteristics
The manufacturer or his agent shall organise a system of references that allows for the following:  identification of exactly which characteristics have to be assessed (see Clause 4.3);  those characteristics that will be assessed;  values, classes, categories, etc. that have been determined for those characteristics.
This system shall be documented as part of the evaluation of conformity.

7.2 Measurement of photometric and energy characteristics When measuring in accordance with EN 410 and EN 12898, using an appropriate spectrophotometer, then three measurements per characteristic shall be made. The specimen shall be mounted in the spectrophotometer and a measurement made. Then the specimen shall be demounted, remounted and a further measurement made. This shall be repeated until the three measurements have been made. The average of the three measurements for each characteristic shall be used for the evaluation of the characteristic as required by Table 3. Note: These three measurements are made to remove any possible angular influence caused by the mounting of the measurement specimen.
