ISO 13897:2018规定了当混合牙科汞齐合金粉末和牙科汞以生产牙科汞齐时，用于含有牙科汞齐合金粉末和牙科汞的可重复使用混合胶囊的要求，以及用于确定符合这些要求的试验方法。 注:ISO 7488规定了混合机的要求。ISO 7488未涉及混合胶囊的要求，尽管混合胶囊是混合机的重要组成部分。

ISO 13897:2018 specifies the requirements for reusable mixing-capsules intended to contain dental amalgam alloy powder and dental mercury when these are mixed to produce dental amalgam, and the test methods used to determine conformity to these requirements. NOTE ISO 7488 specifies requirements for mixing machines. The requirements for mixing-capsule are not dealt with in ISO 7488, although the mixing-capsule is an essential part of the mixing machine.
