标准范围

本国际标准规定了一种比色比较法，用于测定酚醛模塑件中的氨和铵化合物。注:本国际标准未提供氨含量的绝对测量值。当金属嵌件腐蚀或材料污染时，模制制品中的氨含量非常重要必须考虑与物品接触的食品。

This International Standard specifies a colorimetric comparison method for the determination of the amount ofammonia and ammonium compounds in phenol-formaldehyde mouldings.NOTE This International Standard does not provide an absolute measure of the amount of ammonia present.The amount of ammonia in a moulded article is of importance when corrosion of metal inserts or contamination offoodstuffs in contact with the article has to be considered.
