Evaluation of conformity of“Heat strengthened soda lime silicate glass” to hE N 1863-24.3.1.1 GeneralThe characteristics of heat strengthened sodalime silicate glass are in general those of theglass substrate (see 4.3.1.2).4.3.1.2 Characteristics of the soda lime silicateglass panes used for the production ofheat strengthened soda lime silicateglassCharacteristics, generally, those of the incomingraw material, i.e. basic soda lime silicate glassproduct or coated soda lime silicate glassproduct.Panes shall be made of soda lime silicateglass according to EN 572-1, EN 572-2,EN 572-4, EN 572-5. The panes may becoated according to EN 1096–1, EN 1096-2,EN 1096-3 and/or enamelled according toEN 1863-1.For the characteristics listed in Table 1, forthe soda lime silicate glass panes, generallyaccepted values or calculated values may beused.Since the majority of the characteristics ofTable 1 are not changed significantly by theheat strengthening process they shall be usedfor heat strengthened soda lime silicate glass.The exceptions shall be the characteristicbending strength (f g,k) and the resistanceagainst sudden temperature changes andtemperature differentials.The values given for resistance against suddentemperature change and characteristic bendingstrength (f g,k), see 4.3.2.8 and 4.3.2.9, areguaranteed by compliance with this standard.11Table 1: Information on thecharacteristics of soda lime silicate glasspanes, according to EN 572-1, used forthe production of heat strengthened sodalime silicate glassIf some coatings, i.e. coated glass conformingwith the EN 1096 series, when heat treatedchange their radiometric properties themanufacturer shall refer to the followingfor the determination of the appropriatecharacteristics, etc.:• 4.3.2.11 for the emissivity;• 4.3.2.12 for the light transmittance andreflectance;• 4.3.2.13 for the solar energytransmittance;• EN 1096-2 for the durability of A, B andS coatings;• EN 1096-3 for the durability of C andD coatings.If such changes occur then it is the responsibilityof the heat strengthened glass manufacturer todetermine the values to be quoted.However, the coated glass supplier may beable to give values for the heat treated producttogether with appropriate factory productioncontrol tests. Therefore the heat strengthenercan quote applicable values as well as ensuringthat the product values are maintained withoutthe need to undertake these determinations.

Construction Products Directive4.3.2 Determination of characteristics of heatstrengthened soda lime silicate glassproducts12If the heat strengthened glass manufacturerwishes to claim that any performancecharacteristic is independent of theproduction equipment used then the factoryproduction control system shall be inaccordance with this standard including hisspecific process control conditions4.3.2.1 Safety in the case of fire – Resistanceto fire (1)Fire resistance shall be determined andclassified in accordance with EN 13501-2.4.3.2.2 Safety in the case of fire – Reaction tofire (2)Reaction to fire shall be determined andclassified in accordance with EN 13501-1.4.3.2.3 Safety in the case of fire – External firebehaviour (3)Where the manufacturer wishes to declareexternal fire performance (e.g. when subjectto regulatory requirements), the product shallbe tested and classified in accordance withEN 13501-5.4.3.2.4 Safety in use – Bullet resistance: Shatterproperties and resistance to attack (4)Bullet resistance shall be determined andclassified in accordance with EN 1063.4.3.2.5 Safety in use – Explosion resistance:Impact behaviour and resistance toimpact (5)Explosion resistance shall be determined andclassified in accordance with EN 13541.Glass CANNOT be tested for resistance to fireon its own. The tests have to be undertaken ina glazed assembly.The glazed assembly is regarded as a “virtualassembly” 7 and is detailed in the officialclassification report.Heat strengthened soda lime silicate glassproducts are products/materials that do notrequire to be tested for reaction to fire (e.g.Products/materials of Classes A1* according toCommission Decision 96/603/EC, as amended2000/605/EC).The present situation is that there are fourdifferent test methods in ENV 1187. Theapplicability of these tests to glass is not totallyclear. However, before deciding to test it isparamount that the manufacturer checks if thisparticular glass product type is permitted, bynational regulations, in this application.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.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.7Sectorial Group 09 – Glass in building: Determination of the fire resistance performance of glazed assemblies (Virtualassemblies)

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.

Construction Products Directive4.3.2.10 Protection against noise – Direct airbornesound reduction (10)The sound reduction indexes shall bedetermined in accordance with EN 12758.However, the information supplied with theincoming glass may be used as the heatstrengthening process does not alter thevalues.4.3.2.11 Energy conservation and heat retention– Thermal properties (11)EN 12758 gives generally accepted valuesthat can be used in the absence of measureddata. Hence there is no reason to test thischaracteristic.14The thermal transmittance value (U-value)shall be determined by calculation inaccordance with EN 673 with:• emissivity ε: the declared value of the glassmanufacturer. If the information is notavailable, the emissivity shall be determinedin accordance with EN 12898;• nominal thickness of the glass panes.4.3.2.12 Energy conservation and heat retention –Radiation properties: Light transmittanceand reflectance (12)The light transmittance and reflectance shallbe determined in accordance with EN 410.4.3.2.13 Energy conservation and heat retention– Radiation properties: Solar energycharacteristics (13)The solar energy transmittance andreflectance shall be determined in accordancewith EN 410.The information supplied with the incomingmaterial can be used if the heat strengtheningprocess does not alter the values.If the heat strengthening process alters theemissivity then the value must be determined inaccordance with EN 12898. The determinationshould be obtained on a heat strengthenedsample.The information supplied with the incomingmaterial can be used if the heat strengtheningprocess does not alter the values.The information supplied with the incomingmaterial can be used if the heat strengtheningprocess does not alter the values.

Evaluation of conformity of“Heat strengthened soda lime silicate glass” to hE N 1863-2Attachment 2: hEN Clause 5 Evaluation of conformity5.2.2 Initial type testing of heat strengthenedsoda lime silicate glass5.2.2.1 GeneralTo establish if a product conforms to thedefinition of heat strengthened soda limesilicate glass, initial type testing shall consistof:a) mechanical strength measurement inaccordance with EN 1863-1;b) fragmentation test in accordance withEN 1863-1.5.2.2.2 Test specimensThe test specimens needed for the initialtype test shall be processed from float glassaccording to EN 572-1 and EN 572-2 inaccordance with this standard.The “simplest” type of edge work specifiedin the manufacturer’s production controldocumentation shall be used. However, if anarrissed edge is used then all other types ofedge working are deemed to satisfy.The number of test specimens is as follows:a) For mechanical strength measurementthey are given in Table 2a for float glass,Table 2b for coated float glass andTable 2c for enamelled float glass.b) For fragmentation 5 test specimens perthickness are required.5.2.2.3 Test resultsa) When the mechanical strength ismeasured, no measured value shall bebelow that given in clause 9 of EN 1863-1.However, if one value falls below then themanufacturer shall ensure that the resultsrelate to a 5 % probability of breakage atthe lower limit of the 95 % confidenceinterval.b) In the fragmentation test, no test specimenshall exhibit a fragmentation assessmentthat does not meet Clause 8.5 ofEN 1863-1.Mechanical strength shall meet the requirementin EN 1863-1 Clause 9 when determined inaccordance with Annex B.1.1 of EN 1863-2.Fragmentation test is detailed in EN 1863-1Clause 8.Initial type testing is undertaken on float glass,both coated and uncoated if appropriate.The tables detail the number of test specimensrequired for the 4-point mechanical strengthtest.[If a larger range of thicknesses is produced,than the table covers, then the manufacturermay wish to consider 2 specimens perthickness. This will give proof that all thicknessesmeet the strength requirement.]For all products/thicknesses fragmentation testsmust be undertaken.15

Construction Products Directive5.2.2.4 Measurement of surface pre-stressThe manufacturer may also use surfacepre-stress measurement as a means ofproduct control. If this is done then all testspecimens shall be measured prior to testing.This will show the relationship betweensurface pre-stress and mechanical strength/fragmentation.Manufacturers with more than one productionline may perform the initial type test onspecimens from one line. The outcome valueof surface pre-stress measurement may thenbe used as reference for the other productionlines and shall be confirmed by factoryproduction control (FPC). This may also beapplied to new production lines.5.2.2.5 Heat strengthened patterned glassMeasurement of surface pre-stress can beundertaken as a means of product control(see Annex A – Table A.1 – 3.1.3 of 1863-2).The test should be undertaken as detailed inAnnex B.1.2.16Initial type testing of heat strengthenedpatterned glass may not be undertaken asa result of the wide variety of patternedsurfaces of patterned glass in accordancewith EN 572-5.Compliance of heat strengthened patternedglass shall be ensured by the sampling duringproduct control given in Annex A – Table A1– 3.1.4 together with either 3.1.5 or 3.1.6.If a manufacturer only heat strengthens a smallnumber of pattern types/thicknesses then it maybe worthwhile to subject test specimens to themechanical strength and fragmentation tests,(see 5.2.2.1).However, a manufacturer can produce theseproducts as long as they ensure by the factoryproduction control, especially product control,that they meet the requirements.Attachment 3: hEN Clause 6 Marking and labelling6.2 Product markingThe heat strengthened soda lime silicateglass product shall be marked in accordancewith Clause 11 of EN 1863-1.The manufacturer shall permanently mark with:• name or trade mark• EN 1863Attachment 4: hEN Annex A Factory production controlAnnex ATable A.1Factory production control requirementsThis is covered in the GEPVP seconddocument “Evaluation of conformity”.Table A1 applies to all types of heatstrengthened soda lime silicate glass.The generalities are covered in the GEPVPsecond document “Evaluation of conformity”.These cover:• Incoming raw materials• Process control• Product control
