Scope

Scope: This standard specifies the basic requirements, inspections, tests, test classification and grade appraisal for the detection and control of valve leakage, the implementation of control measures, marking, valve qualification certificates, and re-testing, as well as the leakage measurement method using the suction method. This standard applies to valves with leakage requirements that operate at temperatures ranging from -29°C to 538°C, with nominal sizes ≤ DN600 and nominal pressures ≤ PN250 or CLASS 1500. Main technical content: I. The standard consists of 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 main drafters. III. The introduction section mainly explains the necessity of formulating this standard, and its significant practical and historical significance in adapting to international trends, improving valve product quality, and reducing environmental pollution. IV. The main content of the standard text includes basic requirements, inspections, tests, test classification and grade appraisal, implementation of control measures, marking, valve qualification certificates, and re-testing, as well as the leakage measurement method using the suction method. V. The appendix mainly introduces the principle, equipment, operation, judgment, and comprehensive requirements of the suction method measurement method.
