Foreword
Section 5.3 of this Standard is compulsory; the rest are voluntary.
This Standard was drafted according to the rules specified in GB/T 1.1-2009.
This Standard replaces GB 12952-2003 "Polyvinyl Chloride Plastic Sheets for
Waterproofing". Compared with GB 12952-2003, the main technical changes in this
Standard are as follows.
- The product classification was modified (see Chapter 4 in this Standard;
Chapter 3 in Version 2003);
- The static load resistance, peeling off seam strength, tear resistance, water
absorption and wind uplift resistance were added; adhesion at shearing was
deleted (see Section 5.3 in this Standard; Section 4.3 in Version 2003);
- The classification of Type I and II was deleted; heat ageing and artificial
weathering test time were added (see Section 5.3 in this Standard; Section 4.3
in Version 2003);
- The test methods in GB/T 328 were adopted (see Chapter 6 in this Standard;
Chapter 5 in Version 2003);
- The wind uplift resistance test method was added (see Appendixes A and B).
This Standard is not equivalent to ASTM D4434. Appendix A of this Standard refers to
ANSI/FM 4474-2004 "Evaluating the Simulated Wind Uplift of Roof System with Static
Positive Pressure and/or Negative Pressure"; Appendix B of this Standard refers to
ETAG 006.2007 "Guideline for European Technical Approval of Systems of
Mechanically Fastened Flexible Roof Waterproofing Membranes".
This Standard was proposed by China Building Materials Federation.
This Standard shall be under the jurisdiction of Subcommittee on Building Waterproof
Materials of National Technical Committee on Light and Decorative Materials of
Standardization Administration of China (SAC/TC 195/SC 1).
Chief Drafting Organizations of this Standard. China Building Materials Academy
Suzhou Waterproof Research Institute, Technical Supervision & Research Center for
China Building Material Industry, China National Building Waterproof Association, and
Shanghai Research Institute of Building Sciences (SRIBS).

3 Terms and Definitions
For the purpose of this Standard, the terms and definitions given in GB/T 18378 AND
the following terms and definitions apply.
3.1
Homogeneous polyvinyl chloride plastic waterproofing sheets
Polyvinyl chloride plastic waterproofing sheets where no internally reinforcing
materials or backing materials are adopted.
3.2
Polyvinyl chloride plastic waterproofing sheets backed with fabric
Polyvinyl chloride plastic waterproofing sheets where fabrics, such as polyester
nonwoven fabrics, are compounded on the lower surface of plastic sheets.
3.3
Polyvinyl chloride plastic waterproofing sheets internally reinforced with fabric
Polyvinyl chloride plastic waterproofing sheets which are reinforced in the middle of
plastic sheets with polyester or fiberglass mesh fabric.
3.4
Polyvinyl chloride plastic waterproofing sheets internally reinforced with glass
fibers
