本文件规定了建筑用平板热强化钠钙硅酸盐玻璃的产品定义、产品特性（即公差、平整度、边缘加工）、断裂特性（包括碎片）以及物理和机械特性。 本文件不包括热强化后的表面成品玻璃（例如喷砂、酸蚀）。 本文件不包括弯曲（弯曲）玻璃。 本文件中未规定的其他要求可适用于组合件（如夹层玻璃或中空玻璃单元）或经过额外处理（如涂层）的热强化钠钙硅酸盐玻璃。附加要求在相应的玻璃产品标准中规定。在这种情况下，热强化钠钙硅酸盐玻璃不会失去其机械或热特性。

This document specifies product definitions, product characteristics (i.e. tolerances, flatness, edgework), fracture characteristics, including fragmentation, and the physical and mechanical characteristics of flat heat strengthened soda lime silicate glass for use in buildings. This document does not cover surface finished glasses (e.g. sandblasted, acid etched) after heat strengthening. This document does not cover curved (bent) glass. Other requirements, not specified in this document, can apply to heat strengthened soda lime silicate glass which is incorporated into assemblies (e.g. laminated glass or insulating glass units), or undergoes an additional treatment (e.g. coating). The additional requirements are specified in the appropriate glass product standard. Heat strengthened soda lime silicate glass, in this case, does not lose its mechanical or thermal characteristics.
