Scope

Scope: This standard specifies the basic requirements, inspections, tests, test classification and grade identification for the detection and control of valve leakage, as well as the implementation of control measures, marking, valve qualification certificates, re-testing, and the use of the suction method for leakage measurement. This standard applies to valves with leakage requirements operating at temperatures between -29°C and 538°C, with nominal sizes ≤ DN600 and nominal pressures ≤ PN250 or CLASS 1500. Main technical content: I. The standard includes four parts: 1. Preface 2. Introduction 3. Standard text 4. Appendix II. The preface mainly includes the drafting basis, referenced standards, the unit proposing and coordinating the standard, the main drafting units and key drafters. III.
