本欧洲标准规定了用于建筑物的单片平板热增韧碱土金属硅酸盐安全玻璃的公差，平整度，碎片，碎裂和物理和机械特性。 关于弯曲热增韧碱土硅酸盐安全玻璃的信息在附件A中给出，但本产品不构成本欧洲标准的一部分。 本欧洲标准未规定的其他要求可适用于加入到组件中的热增韧碱土金属硅酸盐安全玻璃。夹层玻璃或绝缘单元，或进行额外的处理，例如。涂层。附加要求在相应的产品标准中规定。在这种情况下，热增韧碱土硅酸盐安全玻璃不会失去其机械或热特性

This European Standard specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened alkaline earth silicate safety glass for use in buildings. Information on curved thermally toughened alkaline earth silicate safety glass is given in Annex A, but this product does not form part of this European Standard. Other requirements, not specified in this European Standard, can apply to thermally toughened alkaline earth silicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating units, or undergo an additional treatment, e.g. coating. The additional requirements are specified in the appropriate product standard. Thermally toughened alkaline earth silicate safety glass, in this case, does not lose its mechanical or thermal characteristics.
