GB 18173 Polymer water-proof materials is divided into 4 parts.
?€? Part 1. Water-proof sheet;
?€? Part 2. Waterstop;
?€? Part 3. Hydrophilic expansion rubber;
?€? Part 4. Rubber gasket for shield-driven tunnel.
This Part is Part 1 of GB 18173.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009. This Part replaces GB 18173.1-2006 Polymer water-proof materials - Part 1. Water-proof sheet.
The major differences between this Part and GB 18173.1-2006 are as follows. ?€? MODIFY and ADD some terms and definitions (SEE Sections 3.1, 3.3,
3.4, 3.5, 3.6 and 3.7 of this Part, Sections 3.1, 3.3 and 3.4 of 2006 edition); ?€? ADD the types, technical indicators and relevant detection methods of the water-proof sheets, such as self-adhesive sheets, special-shaped sheets, etc. (SEE Sections 5.3.3, 5.3.4, 6.3.2.2 and 6.3.13 of this Part);
?€? DELETE the reclaimed rubber (JL4) water-proof sheets in the
homogeneous sheets (SEE Section 4.1 of 2006 edition);
?€? ADJUST the physical property indicators of some homogeneous sheets
and composite sheets (SEE Sections 5.3.1 and 5.3.2 of this Part, Section 5.3.1 of 2006 edition);
?€? ADJUST the composite strength indicator and test method for the
surfaces and cores of Type FS2 composite sheets (SEE Section 5.3.2
and Annex E of this Part, Section 5.3.2 of 2006 edition).
This Part makes reference to JIS A 6008.2002 Roofing sheets of synthetic polymer and ASTM D6134.2007 Standard specification for vulcanized rubber sheets used in waterproofing systems, and also amends the original standard Polymer water-proof materials -
