Construction Products Directive 12 4.2.2.5 Safety in use – Explosion resistance: Impact behaviour and resistance to impact (5) Explosion resistance shall be determined and classified in accordance with EN 13541. 4.2.2.6 Safety in use – Burglar resistance: Shatter properties and resistance to attack (6) Burglar resistance shall be determined and classified in accordance with EN 356. 4.2.2.7 Safety in use – Pendulum body impact resistance: Shatter properties (safe breakability) and resistance to impact (7) Pendulum body impact resistance shall be determined and classified in accordance with EN 12600. 4.2.2.8 Safety in use – Mechanical resistance: Resistance against sudden temperature changes and temperature differentials (8) The resistance against sudden temperature changes and temperature differentials is a generally accepted value that is given in EN 572-1 and shall be ensured by compliance with this standard. 4.2.2.9 Safety in use – Mechanical resistance: Resistance against wind, snow, permanent load and/or imposed loads of the glass unit (9) The mechanical strength of basic soda lime silicate glass is a characteristic value that is given in EN 572-1 and is ensured by compliance with this standard. As long as on the concerned construction or building site no part of prEN 13474 is applicable then the current method of determining mechanical resistance in the country of destination shall be applied. The manufactured or supplied thickness of soda lime silicate glass shall conform to the ordered thickness. Basic soda lime silicate glass products would not be expected to pass this test method. NPD is the appropriate information for the CE marking label/accompanying information. Basic soda lime silicate glass products would not be expected to pass this test method. NPD is the appropriate information for the CE marking label/accompanying information. Basic soda lime silicate glass products would not be expected to pass this test method. The exceptions being special types of polished wired glass and wired patterned glass. EN 572-1 gives a generally accepted value of 40 K. Note 1: This value is influenced by edge quality and glass type. Note 2: This value may not be the design value adopted for use in, for example, thermal stress calculations. EN 572-1 gives a value for the characteristic bending strength ( f g,k ) of 45 x 10 6 Pa. Note: The characteristic bending strength has to be used in conjunction with the design method given in prEN 13474 1 . Supplying what was ordered, in terms of thickness, will cover this characteristic. 1 prEN 13474: This standard is being drafted. It will consist of the following three parts: - determination by calculation of the resistance to load of glass used in fenestration; - determination by calculation of the resistance to load of glass used in common non-structural applications other than fenestration; - general basis of design.
Evaluation of conformity of “Basic soda lime silicate glass products” to hE N 572-9 4.2.2.10 Protection against noise – Direct airborne sound reduction (10) The sound reduction indexes shall be determined in accordance with EN 12758. 4.2.2.11 Energy conservation and heat retention – Thermal properties (11) EN 12758 gives generally accepted values that can be used in the absence of measured data. Hence there is no reason to test this characteristic. The thermal transmittance value (U-value) shall be determined by calculation in accordance with EN 673 with: • emissivity ε using the value of emissivity as given in EN 572-1 • nominal thickness of the glass panes 4.2.2.12 Energy conservation and heat retention – Radiation properties: Light transmittance and reflectance (12) The light transmittance and reflectance shall be determined in accordance with EN 410. 4.2.2.13 Energy conservation and heat retention – Radiation properties: Solar energy characteristics (13) The solar energy transmittance and reflectance shall be determined in accordance with EN 410. EN 572-1 gives a value for the corrected emissivity of 0,837. Therefore no necessity to have this characteristic measured. These values need to be determined in accordance with the standard EN 410. The manufacturer is responsible for ensuring, via the factory production control (see Tables A1 to 6), that the product continues to have the same values. These values need to be determined in accordance with the standard EN 410. The manufacturer is responsible for ensuring, via the factory production control (see Tables A1 to 6), that the product continues to have the same values. 13 Attachment 2: hEN Clause 5 Evaluation of conformity 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 economised 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. The chemical composition and determination of whether or not the glass is clear need to be determined. Details of composition, method of determining whether glass is clear or tinted and acceptance levels are given in EN 572-1. Any glass called tinted, which could also include white (also known as low-iron glass), does not need to be checked to determine if it is clear. Thickness, including tolerances, is given in the relevant product standard, i.e. EN 572 Part 2 to 7.
