适用范围：This standard specifies mandatory and supplementary markings of control valves. Some mandatory markings may be inappropriate for some valves of very special design, and some supplementary markings may be appropriate only to specific types of control valves. It is recommended that the marking of all valves conform to this standard whenever possible unless otherwise agreed between manufacturer and purchaser.Mandatory markings shall be located in such a way that markings remain permanently. Mandatory markings shall be integral with the valve body or on a plate (distinct from an identification plate) securely fixed to the body.The location of supplementary markings is also specified. Usually these are on an identification plate.This Part 5 supersedes Clause 7 of IEC Publication 534-1: Industrial-process Control Valves, Part 1: General Considerations.
