GB/T 26518-2011 in English

《GB/T 26518-2011高分子增强复合防水片材》由TC35（全国橡胶与橡胶制品标准化技术委员会）归口，TC35SC7（全国橡胶与橡胶制品标准化技术委员会橡胶杂品分会）执行，主管部门为中国石油和化学工业联合会。

1 Scope

This standard specifies the product classification and labeling, requirements, test methods, inspection rules as well as marking, packaging, transportation and storage of the reinforced and composite polymeric sheets for water proof (hereinafter referred to as "the sheets").

This standard is applicable to sheets made of polymer materials such as polyethylene and ethylene-vinyl acetate copolymer as the main materials and composite fabrics as the protection or reinforcement layer, and used for water proof and moisture proof of structures such as roof, indoor, wall, hydraulic and water conservancy facilities and underground engineering, as well as water proof of various green planting roof.

3 Product classification and labeling

3.1 Product classification

Sheets are classified into the following two categories according to the main materials:

a) polyethylene composite environment-friendly sheet with a type code of F-PE;

b) ethylene-vinyl acetate copolymer composite environment-friendly sheet with a type code of F-EVA.

3.2 Product marking

3.2.1 Labeling method

The product shall be labeled in the sequence below, and the labeling contents may be added as required:

Type code - specification (length × width × thickness) - standard No.

3.2.2 Labeling example
