Foreword
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents".
Drafting.
This document replaces GB/T 28408-2012 "Protective Clothing - Insect-Proof Clothing". Compared with GB/T 28408-2012, the main differences are in the structural design.
Aside from the integration and editorial changes, the main changes are as follows.
a) Terms and definitions have been changed (see Chapter 3, Chapter 3 of the.2012 edition);
b) The technical requirements for the style structure have been changed (see 4.1, 4.2.1 of the.2012 edition);
c) The technical requirements for the insect-repellent performance of the fabric have been changed (see 4.3.1.1, 4.1.2 in the.2012 edition);
d) Added technical indicators and tests for formaldehyde content, pH value, decomposable carcinogenic aromatic amine dyes, and odor in insect-repellent protective clothing fabrics.
Methods (see 4.3.1.2, 5.10~5.13);
e) The safety and hygiene requirements for fabrics have been removed (see 4.1.1 in the.2012 version);
f) The technical specifications for sewing finished garments have been changed (see 4.3.2.2, 4.2.4 in the.2012 edition);
g) The technical specifications for the dimensional change rate of finished garments after washing have been revised (see 4.3.2.3, 4.2.5 in the.2012 edition);
h) The requirements for formaldehyde content and pH value of finished garments have been removed (see 4.2.5 of the.2012 version);
i) The test method for the insect-repellent properties of fabrics has been changed (see 5.1, 5.1 and 5.2 in the.2012 edition);
j) Changes have been made to the labeling, information that manufacturers should provide, and packaging (see Chapter 6, Chapters 7 and 8 of the.2012 edition);
k) The detection rules have been removed (see Chapter 6 of the.2012 edition);
l) The washing method has been removed (see Appendix A of the.2012 edition).
