Some standard content:
GB/T 2662--1999
This standard is the first revision of GB/T 2662-1981. The name of this standard was changed during the revision. The original name of the standard did not match the definition of the scope of application. It is now changed to "Cotton Clothing" and the main contents such as reference standards, technical regulations for warp and weft yarns, physical and chemical performance requirements, and defect determination have been added. Other technical contents have also been greatly changed.
Appendix A of this standard partially adopts the provisions of GB/T8688-1988 "Test Method for Seam Detachment of Wool Woven Fabrics".
Appendix A of this standard is the appendix of the standard.
This standard shall be implemented from January 1, 2000. From the date of entry into force, this standard shall also replace GB/T2662-1981. This standard is proposed by the State Textile Industry Bureau. This standard is under the jurisdiction of the Secretariat of the National Technical Committee for Clothing Standardization. This standard was drafted by Shanghai Garment Research Institute, Jiangsu Garment Corporation, Jiangsu Meierzi Group Corporation, Shanghai Down Garment Factory, and Shanghai Feida Down Garment Factory. It was drafted in collaboration with the National Garment Quality Supervision and Inspection Center (Shanghai) and Shanghai Garment, Shoes and Hats Business Association.
The main drafters of this standard are Xu Yunbao, Xu Jian, Zhou Qihong, Xu Rongguang, Wu Lijia, and Zhou Pu. 231

Appendix A
(Appendix to the standard)
Test method for the degree of seam disengagement
Apply a certain load in the direction perpendicular to the fabric seam, the seam disengages, and measure the maximum distance of its disengagement. A2 Load applied
Fabric: 120N±5N; Lining: 70N±5N. A3 Equipment and materials
A3.1 For ordinary household and industrial sewing machines, the sewing needles should be of the type suitable for the fabric used. A3.2 Sewing threads should be of the quality suitable for the fabric used. A3.3 The distance between the upper and lower clamps of the fabric strength machine is 10.0cm, and the lower clamp descends at a speed of 5.0cm/min when there is no load. The pre-tension is determined according to the mass per unit area of the specimen, see Table A1. Table A1

A5.1 Finished product sampling size 5.0cm×20.0cm (including the clamping part), if cut from the fabric is 5.0cm×30.0cm, its edges should be parallel to the warp and weft threads.
A5.2 Number of samples Cut three pieces from the radial direction of the fabric or finished product. A5.3 Fold the cut sample in half and sew it with a sewing machine at a position parallel to the crease mark 1.3cm. And tie the suture firmly, and finally open the sample along the suture.
A6 Test steps
A6.1 Separate the two clamps of the strength machine to 10.0cm. The edges of the two clamps must be parallel to each other and perpendicular to the moving direction. A6.2 Fix the sample in the middle of the clamp (first hang a preload clamp suitable for the mass per unit area of the fabric on the lower end of the sample, and then tighten the lower clamp) so that the seam and the edge of the clamp are parallel to each other. A6.3 Gradually increase the load at a speed of 5.0cm/min to 120N±5N for the outer material and 70N±5N for the lining, stop the lower clamp from descending, and then measure the maximum distance of the seam separation vertically on the strength machine. See Figure A1.2.12
