GEPVP CPD 6 (EN1863-2) EN.indd - Glass for Europe

Evaluation of conformity of“Heat strengthened soda lime silicate glass” to hE N 1863-24.3.2.6 Safety in use – Burglar resistance:Shatter properties and resistance toattack (6)Burglar resistance shall be determined andclassified in accordance with EN 356.4.3.2.7 Safety in use – Pendulum body impactresistance: Shatter properties (safebreakability) and resistance to impact (7)Pendulum body impact resistance shall bedetermined and classified in accordance withEN 12600.4.3.2.8 Safety in use – Mechanical resistance:Resistance against sudden temperaturechanges and temperature differentials (8)The resistance against sudden temperaturechanges and temperature differentials isa generally accepted value that is givenin EN 1863-1 and shall be ensured bycompliance with this standard.4.3.2.9 Safety in use – Mechanical resistance:Resistance against wind, snow,permanent load and/or imposed loads ofthe glass unit (9)The thickness of heat strengthened sodalime silicate glass is a characteristic valuethat is given in EN 1863-1 and is ensured bycompliance with this standard.As long as on the concerned constructionor building site no part of prEN 13474is applicable then the current method ofdetermining mechanical resistance in thecountry of destination shall be applied.The manufactured or supplied thickness ofheat strengthened glass shall conform to theordered thickness.Heat strengthened soda lime silicate glass wouldnot be expected to pass this test method.NPD is the appropriate information for theCE marking label/accompanying information.If a manufacturer wants to make a performanceclaim then the heat strengthened soda limesilicate glass shall be tested to EN 12600.Classification should be α(A)Φ, where α and Φare dependent upon product thickness/type.EN 1863-1: Clause 10.3 gives a generallyaccepted value of 100 K.EN 1863-1 gives values for the mechanicalstrength of heat strengthened soda lime silicateglass as follows:Float: clear )tinted ) -- 70 N/mm 2coated )Enamelled float -- 45 N/mm 2(based on enamelled surface in tension)Patterned glass andSheet glass -- 55 N/mm 2Note: The characteristic bending strength has tobe used in conjunction with the design methodgiven in prEN 13474 8 .Supplying what was ordered, in terms ofthickness, will cover this characteristic.138prEN 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 otherthan fenestration;- general basis of design.
