scope:
This part of IEC 60534 specifies the requirements for the inspection and routine testing of control valves manufactured in conformity with the other parts of IEC 60534. When specified, the inspection and test requirements are taken from this part in conjunction with any additional information required by 4.1, or a code of practice stated by the purchaser.
This standard 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 standard, the standard for hazardous service shall take precedence.
This standard is applicable to valves with pressure ratings not exceeding PN 420 (Class 2500). The requirements for actuators apply only to pneumatic actuators.
