T/CI 114-2022 Active

Scope: This document specifies the terms and definitions, models, materials, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of fluid connectors. This document is applicable to fluid connectors (hereinafter referred to as "connectors"). Main technical content: 5.1 Metal materials: Metal materials should be selected from aluminum alloys, stainless steel, brass, or titanium alloys, etc. 5.2 Sealing ring materials: Sealing ring materials should be selected from fluorosilicone rubber, EPDM rubber, or hydrogenated nitrile rubber, etc. The recommended transmission media for different sealing ring materials are specified in Table 2. When selecting other materials, all performance indicators should meet the requirements of material compatibility. 6. Technical requirements 6.1 Appearance: The surface of the connector should be clean, free from oil stains, and without mechanical damage, burrs, sharp edges, holes, or delamination. The surface of the plating should be firm and smooth, free from oxidation and rust. The rubber parts should be free from hardening, brittleness, or stickiness. 6.2 Pressure resistance: The connector assembly, plug, and socket should be able to withstand a liquid pressure of 2.25 MPa or a gas pressure of 1.75 MPa without permanent deformation or leakage. 6.3 Sealing performance: The connector assembly, plug, and socket should be able to withstand a gas pressure of 1.5 MPa without leakage, and the helium leakage rate should not exceed 1×10-6 Pa·m3/s.
