IEC 60534-4:2021 is available as IEC 60534-4:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the 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.
