: GB/T3917 textile fabric tearing performance, including the following five parts: -- part 1: shock pendulum method determination of tear strength; - part 2: breeches sample (single slit) determination of the tear strength; - part 3: the trapezoid tearing strength determination; - part 4: tongue shape sample (double slit) determination of the tear strength; - part 5: wing sample (single slit) determination of the tear strength. This part is divided into GB/T3917 part 2. This part use translation method of equivalent USES ISO13937 then the textile fabric tearing performance Part 2: breeches sample (single slit) to tear The determination of bursting strength "(English version). This part equivalent USES ISO13937 "04, and ISO13937 compared" 04: there are differences - delete the introduction of international standards; - delete the note in chapter 1; --, normative reference files by alternative in China standard The corresponding international standards; - increases the figure 1 and figure b. c. 1 of the figure. This section instead of GB/T3917.2-1997 textile fabric tearing performance Part 2: tongue sample single tongue method of determination of tear strength. This section with the method of GB/T3917.2-1997 single tongue main differences To: --, increased the inapplicable scope; --, normative reference file to increase the standard of the equipment debugging; - increased by 3.2, added effective clamping line test; - increased by 3.3 note; - increased by 3.4 note, explain the method of choosing effective peak; - increased by 6. 1 general provisions
of the specific standard of instrument debugging; - the width of the clamp by at least 50 mm changed to more suitable to use 75 mm; - increases the width is 200 mm wide specimen and its operation method; - increased by 9.4 recording paper paper feed rate and instrument of stretching rate ratio is 2:1; -- -- -- To edit 10.1.1 modify and delete the note 2; - increased 10.1.5 each sample of the six largest peak average calculation; --, appendix C increased peak selecting method of approximate calculation. The appendix D for normative appendix of this section. Appendix A, appendix B, appendix C for informative appendices . This part put forward by China textile industry association. This part of the national textile standardization technology committee basic standards branch (SAC/TC209 / SC1) under centralized. This section main drafting unit: suzhou fiber inspection, ZhongFang standard inspection certification center (Beijing) co., LTD. This part of the main draftsmen: HangZhiWei , wang ning, would, hai-juan wang, ChuJing. This section instead of the standard all previous releases as: --, GB 3917-1983 tearing strength of fabrics by the tongue(single rip)method
, GB/T 3917.2-1997 Textiles--Tear properties of fabrics--Part 2:Determination of tear force of tongue shaped test specimens
Description:Gb/t 3917 the provisions of this section of the single slit breeches sample method was developed for the determination of fabric tear strength. On the direction of the tear strength measuring fabric from the initial single slit incision tear force to the specified length needed.
this part is mainly suitable for woven fabric, also can be applied to other technical methods of fabric, such as non-woven cloth, etc.
this section does not apply to knitted fabric, woven elastic fabric and likely tear transfer sparse weave And has high anisotropic fabric.
the provisions of this section using uniform elongation tester (cre).
