中文名称:塑料.灰份的测定.第3部分:未增塑的醋酸纤维素
英文名称:Plastics — Determination of ash — Part 3: Unplasticized cellulose acetate
发布日期:1984-05
标准范围
规定了测定灰分的方法,未增塑醋酸纤维素,不含添加剂、填料、染料或其他可能影响结果的材料-点火试验部分,并在马弗炉中煅烧,温度保持在575摄氏度或850摄氏度(按约定)。更高的温度(比如850摄氏度)会将碳酸盐转化为氧化物,从而给出更低的值。应遵循ISO 3451/1中的一般说明。
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.
