T/GDPIA 67-2024 Dual-layer self-curling protective sleeve for preventing collisions for new energy vehicles
Basic Information
Scope
Scope: This document specifies the terms and definitions, requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for impact-resistant double-layered self-winding protective sleeves for new energy vehicles. This document applies to the production and inspection of impact-resistant double-layered self-winding protective sleeves for new energy vehicles with a use temperature range of -40°C to +150°C. The sleeves are made from fabric obtained by interlacing two layers of yarns in a specific manner, with the warp yarns made of polyester filament yarns and the weft yarns and the hems made of polyester monofilament yarns.
