T/GTES 14-2025 Polymer porous filter cartridge
Basic Information
Scope
Scope: This document specifies the terms and definitions of polymer porous filter elements, product models and their markings, requirements, test methods, inspection rules, packaging, transportation, and storage. This document applies to filter rods, filter sheets, or filter blocks with multiple-stage internal channels, which are characterized by liquid or gas transmission or filtration performance and are prepared from polymer fiber bundles or polymer resin powders. This document does not apply to porous materials composed of polymers and other non-polymeric materials, as well as filter core materials with porous structures obtained by traditional plastic foaming processing methods and non-woven fabric needle-punching processing methods.
