Introduction of GB/T 18887-2023

Geosynthetics - Geocomposites made of woven/nonwoven geotextiles 1 Scope This document specifies the product classification, specification and code, technical requirements, inspection rules, packaging, storage, transportation and marking of geocomposites made of woven/nonwoven geotextiles, and describes the corresponding test methods. This document is applicable to geocomposite products of filament woven geotextiles or split film silk woven geotextiles (woven geotextiles) made of polymer (raw material) and staple fiber nonwoven geotextiles by needle punching process. It may be used as a reference for other similar products. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document.
