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 17639-2008 "Geosynthetic filament spunbonded needle-punched nonwoven geotextiles", and GB/T 17639-
Compared with:2008, except for structural adjustment and editorial changes, the main technical changes are as follows:
a) The types of raw materials are specified in the scope (see Chapter 1, Chapter 1 of the:2008 edition);
b) Added a chapter on terms and definitions (see Chapter 3);
c) The product classification is divided into polyester and polypropylene according to the raw materials: The types of fibers such as nylon and polyethylene are deleted, and the words "will be divided according to the structure" are deleted:
Divided into common type and composite type" (see 4:1, 3:1 of the:2008 edition);
d) The recommended specifications for polyester products have been changed, and the recommended specifications for polypropylene products have been added (see 4:2, 3:2 of the:2008 edition);
e) Thickness is added to the product code (see 4:3, 3:3 of the:2008 edition);
f) For the basic technical requirements of polyester filament spunbonded needle-punched nonwoven geotextiles, "nominal breaking strength" is changed to "nominal strength", and
The index specification has been changed; "longitudinal and transverse fracture strength" has been changed to "longitudinal and transverse tensile strength", and the index requirements have been adjusted; "longitudinal and transverse
Elongation corresponding to quasi-strength" was changed to "elongation under maximum longitudinal and transverse loads", and the index requirements were adjusted; CBR bursting strength and
Minor adjustments have been made to the index requirements for longitudinal and transverse tear strength; the thickness index has been deleted; the thickness deviation rate and thickness variation have been added
Coefficient of 2 assessment indicators; increased dynamic perforation, longitudinal and transverse fracture strength (grab sample method), anti-ultraviolet performance (xenon arc lamp method), anti-corrosion
Four reference indexes of ultraviolet performance (fluorescent ultraviolet lamp method) (see Table 1, Table 1 of the:2008 edition);
g) Added the basic technical requirements for polypropylene filament spunbonded needle-punched nonwoven geotextiles (see Table 2);
h) The assessment of broken needle residues has been added to appearance defects (see Table 3, Table 2 of the:2008 edition);
i) The corresponding test methods have been adjusted according to the changes in the technical requirements for intrinsic quality and appearance quality (see Chapter 6, Section 5 of the:2008 edition
chapter);
j) Added factory inspection, type inspection and inspection items (see 7:1:1, 7:1:2 and 7:2):
