T/CCTAS 226-2025 Urban (suburban) rail transit SFC type fastening equipment
Basic Information
Scope
Main technical content: SFC-type fasteners are widely used in urban (suburban) railways in China, but there are currently no relevant specifications or general technical standards for SFC-type fasteners. In view of this situation, it is particularly important to formulate technical standards for SFC-type fasteners in urban (suburban) railways. This standard determines the direction of standard preparation by collecting existing engineering application experience, relevant research results, test and inspection results, and feedback information from users. This standard specifies the composition, technical requirements, test methods, inspection rules, marking, packaging, storage and transportation, laying and maintenance requirements of SFC-type fasteners for urban (suburban) railways. It is applicable to SFC-type fasteners used in urban (suburban) railway non-tracked track projects with a design speed of v≤160km/h.
