foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules for Standardization Documents"
drafting.
This document replaces GB/T 32120-2015 "Steel Structure Oxidative Polymerization Coating Anticorrosion Technology", and is consistent with GB/T 32120-2015
In addition to structural adjustments and editorial changes, the main technical changes are as follows.
a) Deleted the term "anti-corrosion mortar" (see 3.4 of the.2015 edition);
b) Delete the anti-corrosion mortar (see 5.2 of the.2015 edition);
c) Change "tensile strength" to "breaking strength" and change the corresponding requirements (see Table 2, Table 3 of the.2015 edition);
d) Added requirements and testing methods for "combustion performance" (see Table 2);
e) Delete the "ignition point" requirements and detection methods (see Table 4 of the.2015 edition);
f) Added steel structure surface treatment (see 6.2.1.2);
g) The filling of anti-corrosion mortar has been deleted (see 6.2.3 of the.2015 edition);
h) The total thickness of anti-corrosion paste and anti-corrosion tape has been changed (see 6.2.3.5, 6.2.4.5 of the.2015 edition);
i) The total thickness of the anti-corrosion layer has been changed (see 7.3.3, 7.3.3 of the.2015 edition);
j) The method of electric spark leak detection has been changed (see 7.4, 7.4 of the.2015 edition).
