ISO 12540:2017涵盖了产品定义、产品特性（即公差、平整度、边缘加工等）、断裂特性（包括碎片）以及建筑用平板钢化钠钙硅酸盐安全玻璃的物理和机械特性。 根据ISO 11485，ISO 12540:2017不包括弯曲（弯曲）玻璃。 本文件中未规定的其他要求可适用于热钢化钠钙硅酸盐安全玻璃，该安全玻璃包含在组件中，例如夹层玻璃或中空玻璃单元，或经过额外处理，例如:。 g、 涂层。附加要求在相应的玻璃产品标准中规定。在这种情况下，热钢化钠钙硅酸盐安全玻璃不会失去其机械或热特性。

ISO 12540:2017 covers product definitions, product characteristics, i.e. tolerances, flatness, edgework, etc., fracture characteristics, including fragmentation, and the physical and mechanical characteristics of flat tempered soda lime silicate safety glass for use in buildings. ISO 12540:2017 does not cover curved (bent) glass according to ISO 11485. Other requirements, not specified in this document, can apply to thermally toughened soda lime silicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating glass units, or undergo an additional treatment, e.g. coating. The additional requirements are specified in the appropriate glass product standard. Thermally toughened soda lime silicate safety glass, in this case, does not lose its mechanical or thermal characteristics.
