The previous released edition substituted by this Part is as follows. — GB/T 18173.3-2002. Polymer water-proof materials - Part 3. Hydrophilic expansion rubber1 ScopeThis Part of GB/T 18173 specifies the terms and definitions, classification and product markings, requirements, test methods, inspection rules, symbols, packaging, transportation and storage for the hydrophilic expansion rubber of polymer water-proof materials. This Part is applicable to the hydrophilic expansion water-proof rubber made of absorbent materials, such as water-soluble polyurethane prepolymer, sodium acrylate polymer absorbent resin, etc., and natural or chloroprene rubber. This kind of rubber is mainly applied to the seams and water-proof sealing of the underground and foundation works, such as tunnels, pipe jacking, civil air defense, etc., and the water-proof sealing of the industrial equipment, such as vessels, locomotives, etc.2 Normative referencesThe following documents are essential to the application of this document.
