标准摘要
[中文适用范围]： ISO 16589 指定使用由基于热塑性材料（例如聚四氟乙烯 (PTFE)）的适当配方化合物制成的密封元件的密封件。 它们被认为适合在低压条件下使用。 ISO 16589 的这一部分对可能损害密封件功能的典型表面缺陷进行了定义和分类，旨在方便购买者和制造商讨论这些缺陷在不同应用中的重要性。 注 ISO 16589 是 ISO 6194 的补充，ISO 6194 涵盖采用弹性体密封元件的密封件。 [外文原描述]： ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low-pressure conditions. ISO 16589-5:2011 defines and classifies typical surface imperfections that could impair the function of the seals, and is intended as a convenience for purchasers and manufacturers in their discussions concerning the importance of these imperfections in different applications.
