Foreword
This Standard was prepared according to the rules specified in GB/T 1.1-2009.
This Standard replaces GB/T 19250-2003 Polyurethane waterproofing coating. Compared
with GB/T 19250-2003, in additoin to edition changes, main changes of this Standard are
as follows.
— MODIFY the product classification. COMBINE the Category I and Category II in
previous version into Type I. ADD new Type II and Type III. Type II products refer
to the requirements of waterproofer cable duct of high-speed railway bridges. Type
III prodcts refer to the requirements of high strength type in JIS A6021 (see Clause
3 and Clause 3 in 2003 edition);
— MODIFY the technical requirements. DIVIDE the performances into basic
performances and optional performances. For basic performance, CANCEL the
adhesion strength items of humid base level in previous version. ADD inspection
items such as levelling performance, adhesion strength, water absorption, and
combustion performance, changed technical indicators (see table 1 and table 2,
table 1 and table 2 in 2003);
— MODIFY the time of artificial weathering aging time. EXTEND the 720h in previous
version to 1000h (see Table 1 in this Standard, and Table 1 in 2003);
— ADD the harmful substance limits (see 5.3);
— MODIFY and ADD test methods (see clause 6 and clause 6 in 2003);
— ADD the informative annex releated to the application fields of products (see
Annex A).
This Standard was proposed by China Building Materials Federation.
This Standard shall be under the jurisdiction of Building Waterproof Material
Subcommittee of National Technical Committee 195 on Constructional Materials and
Decorative Materials of Standardization Administration of China (SAC/TC 195/SC 1).
