本文件已被宣布为“稳定”，不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。本规范涵盖了挤出管材、绳索、胶带和型材形式的聚氯乙烯（PVC）塑料。这些产品通常用作电线上的套管或母线绝缘，尤其是在要求套管透明的情况下，工作温度高达120摄氏度（248华氏度），但使用不限于此类应用。每个申请都应单独考虑。

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This specification covers a polyvinyl chloride (PVC) plastic in the form of extruded tubing, cord, tape, and shapes.These products have been used typically as sleeving on wire or as bus bar insulation, particularly where transparency of the sleeve is desired, for operating temperatures up to 120 degrees C (248 degrees F), but usage is not limited to such applications. Each application should be considered individually.
