Main Technical Content: This document specifies the terms and definitions, classification, technical requirements, test methods, inspection rules, and marking, packaging, storage, and transportation for laboratory valves and switching panels. This document applies to laboratory valves and switching panels with a pressure range of -0.1 MPa to 30 MPa, a pipe diameter of less than 50 mm, and a medium of gas. T/SLEA 0071-2023, "Technical Specifications for Laboratory Gas Supply Valves and Accessories", provides basic technical requirements for laboratory gas supply valves and accessories. It consists of the following four parts: - Part 1: Terminology. The purpose is to define relevant terms for laboratory gas supply valves and accessories. - Part 2: Pipelines and fittings. The purpose is to standardize technical requirements, test methods, and other related requirements for laboratory gas supply pipelines and fittings. - Part 3: Valves and switching panels. The purpose is to standardize technical requirements, test methods, and other related requirements for laboratory gas supply valves and switching panels. - Part 4: Accessories. The purpose is to standardize technical requirements, test methods, and other related requirements for laboratory gas supply accessories. (Note: The CCS number in the standard is defined according to the "Chinese Standard Document Classification Number" used in the regulatory authority system. The classification number used in this platform's database is the 2017 edition of the National Economic Industry Classification Number. The classification numbers in the two systems are inconsistent. When uploading the standard text to this platform, the classification number is selected according to the platform's classification number, so after downloading the standard text, you will see that the CCS number is inconsistent with the classification number selected in this system.)
