39、rmitted tolerance for the characteristic 4 Requirements 4.1 Product description For conformity purposes the thermally toughened glass manufacturer is responsible for the preparation and maintenance of the product description. This description shall describe the product and/or product families. Discl
40、osure of the product description shall be at the discretion of the thermally toughened glass manufacturer or his agent except in the case of regulatory requirements. The description shall contain at least a normative part. The description may also contain an informative part, when the manufacturer f
41、oresees further development of the product. The normative part of the description shall contain the following minimum information: - a reference to EN 13024 parts 1 and 2 and all other standards with which the manufacturer claims compliance. - the radiometric properties and durability of coated glas
42、s, i.e. coated glass that conforms with EN 1096-1, EN 1096-2, EN 1096-3, when those properties are changed, intentionally or unintentionally, by the thermal toughening process. EN 13024-2:2004 (E) 7 The definition of product families shall be consistent with the normative part of the product descrip
43、tion. The substitution of materials shall maintain the conformity with the product description. The substituting material can be added to the product family and also the product description when compliance has been demonstrated. 4.2 Conformity with the definition of thermally toughened borosilicate
44、safety glass Products shall conform to the definition and fulfil the requirements of thermally toughened borosilicate safety glass as defined in EN 13024-1. 4.3 Determination of the characteristics performances 4.3.1 Characteristics of thermally toughened borosilicate safety glass 4.3.1.1 General Th
45、e characteristics of thermally toughened borosilicate safety glass are in general those of the glass substrate ( see 4.3.1.2). 4.3.1.2 Characteristics of the borosilicate glass panes used for the production of thermally toughened borosilicate safety glass Panes shall be made of borosilicate glass ac
46、cording to EN 1748-1-1. The panes may be coated according to EN 1096 1, EN 1096-2, EN 1096-3 and/or enamelled according to EN 13024-1. For the characteristics listed in Table 1, for the borosilicate glass panes, generally accepted values or calculated values may be used. Since the majority of the ch
47、aracteristics of Table 1 are not changed significantly by the thermal toughening process they shall be used for thermally toughened borosilicate safety glass. The exceptions shall be the characteristic bending strength (f g,k ) and the resistance against sudden temperature changes and temperature di
