标准摘要
[中文适用范围]： 本部分 IEC 60534 规定了符合 IEC 60534 其他部分制造的控制阀的检查和例行测试要求。 本文件适用于压力等级不超过 Class 2500 的阀门。执行机构的要求仅适用于气动执行机构。 本文件不适用于放射性服务、消防安全测试或其他危险服务条件的控制阀类型。如果危险服务标准与本文件的要求冲突，应以危险服务标准为准。 注：本文件可通过买方和制造商之间的协议扩展到更高的压力等级。 [外文原描述]： IEC 60534-4:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60534-4:2021 specifies the requirements for the inspection and routine testing of control valves manufactured in conformity with the other parts of IEC 60534. This document is applicable to valves with pressure ratings not exceeding Class 2500. The requirements for actuators apply only to pneumatic actuators. This document does not apply to the types of control valves where radioactive service, fire safety testing, or other hazardous service conditions are encountered. If a standard for hazardous service conflicts with the requirements of this document, the standard for hazardous service should take precedence.
