标准范围

ISO 3451的本部分规定了填充和未填充的聚对苯二甲酸乙二醇酯、聚对苯二甲酸丁二醇酯以及这两种共聚物灰分的测定方法。遵循ISO 3451-1中给出的一般程序。对于未填充材料，使用ISO 3451-1:1997中的方法A或方法C。对于填充材料和玻璃纤维增强材料，使用ISO 3451-1:1997的方法A。对于含有阻燃剂、三氧化二锑和/或其他挥发性添加剂（例如颜料硫化锌）的玻璃纤维填充材料，应进行改性，以将其作为挥发性溴成分去除。

This part of ISO 3451 specifies methods for determination of the ash of poly(ethylene terephthalate), poly(butylene terephthalate) and copolymers of the two, both filled and unfilled. The general procedures given in ISO 3451-1 are followed. For unfilled materials method A or method C of ISO 3451-1:1997 is used.For filled and glass-fibre reinforced materials method A of ISO 3451-1:1997 is used. For glass-fibre filled materials, containing flame retardant, antimony trioxide, and/or other, volatilize additives, for instance pigment zinc sulfide, a modification is incorporated to remove these as volatile bromine component(s).
