标准摘要
[中文适用范围]： 规定了未塑化醋酸纤维素灰分的测定方法，不含可能影响结果的添加剂、填料、染料或其他材料。 -点燃测试部分并在保持在 575°C 或 850°C（按约定）的马弗炉中煅烧。 较高的温度（例如 850°C）会将碳酸盐转化为氧化物，从而给出较低的值。 应遵循 ISO 3451/1 中的一般说明。 [外文原描述]： Specifies a method for the determination of the ash unplasticized cellulose acetate, free of additives, fillers, dyes or other materials, which may affect the result. -Ignition of a test portion and calcination in a muffle furnace maintained at 575 C or 850 C (as agreed). Higher temperatures such as 850 C will convert carbonates to the oxides and thus give lower values. The general instructions in ISO 3451/1 shall be followed.
