GB/T 17641-2017Geosynthetics—Slit and split film yarn woven geotextiles (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

The standard instead of GB/T 17641-1998 "geosynthetics split film woven geotextile", this standard and GB/T 17641-1998, the main technical changes are as follows.

--- Added GB/T 19978, removed GB/T 4668, GB/T 13760 and GB/T 17633, respectively ISO 4892.2.1994 and GB/T 4667 are replaced by GB/T 31899 and GB/T 4666 (see Chapter 2, Chapter 2 of the 1998 edition);

--- The specification of the product specification is changed from "warp rupture strength" to "nominal breaking strength", the mass per unit area is deleted, the width is removed Recommended series (see 3.2, 1998 edition 3.2);

--- the product code in the "lowest to the strong" and "weft to the lowest strength" replaced by "nominal breaking strength", the deletion of the quality per unit area And the production sector number (see 3.3, 1998 version 3.3);

--- adjust the contents of the "Quality Assessment" in Chapter 4 of the 1998 edition to 6.3 "Rules of Decision" and modify some of the contents (See chapter 3, chapter 4 of the 1998 edition);

--- Table 1 specifications from the "11 files" to "9 files" (see Table 1, 1998 version of Table 1);

In Table 1, the "deviation rate per unit area", "thickness deviation rate", "acid and alkali resistance" and "antioxidant performance" Project, the deletion of the "unit area quality" 1 assessment items, "warp rupture strength" and "zonal strength" replaced by "latitude and longitude To the rupture strength ", adjusted warp and weft fracture strength, bursting strength, width deviation rate, warp and weft tear strength and anti-ultraviolet Can be 5 indicators (see Table 1, 1998 version of Table 1);

- Removed 4.3.5 of the 1998 edition (see 4.3.5 of 1998);

- modified the contents of Chapter 6 "Inspection Rules" (see Chapter 6, Chapter 6 of the 1998 edition);

- modified the contents of Chapter 7, "Packaging, Storage and Labeling" (see Chapter 7, Chapter 7 of the 1998 edition).
