Scope
Scope: This standard specifies the terms and definitions of high-density polyethylene geomembranes, the requirements for base resins, product classification, designations and naming, technical requirements, test methods, inspection rules, marking, packaging, storage, and transportation. This standard applies to geomembrane products manufactured using medium-density polyethylene resin (PE-MD) or high-density polyethylene resin (PE-HD) as the main raw materials, combined with various additives, and used in environmental protection and anti-seepage projects. Main technical content: 1. Scope: Defines the terms and definitions of high-density polyethylene geomembranes, base resin requirements, product classification, designations and naming, technical requirements, test methods, inspection rules, packaging, storage, and marking. 2. Normative references: Determines the relevant testing method standards based on the actual quality assessment requirements of the product. 3. Terms and definitions: Clarifies the definitions of high-density polyethylene geomembranes, smooth-surfaced geomembranes, and rough-surfaced geomembranes based on the product composition and classification. 4. Base resin requirements: Specifies the density requirements of resins used in high-density polyethylene geomembranes, as well as the requirements for the use of recycled materials and fillers. 5. Product classification, designations, and naming 5.1 Product classification and designations: Refers to Article 5.1 of GB/T 17643-2011 "Geosynthetic Materials - Polyethylene Geomembranes". The products are divided into smooth-surfaced high-density polyethylene geomembranes and rough-surfaced high-density polyethylene geomembranes. Rough-surfaced high-density polyethylene geomembranes are further divided into single-rough and double-rough surfaces. The designation of smooth-surfaced high-density polyethylene geomembranes is GH-2S, the designation of single-rough high-density polyethylene g
