Scope
Main technical content: This standard has the following main technical features compared with the existing domestic diaphragm inspection standards: 1. Added terms and definitions for diaphragms and skeleton fabrics. 2. Classified diaphragms according to the operating temperature requirements of membrane gas meters, and categorized them by their working temperature ranges. 3. Referencing the EN 549:1994 standard, it specifies the performance requirements for rubber materials used in diaphragms. 4. Specified more detailed performance requirements for diaphragm products, with different technical requirements for softness based on the thickness of the diaphragm. 5. Added technical requirements and test methods for skeleton fabrics.
