Some standard content:
GB/T26642001
This standard is a revision of GB/T2664-1993 "Men's suits and coats". In the revision of this standard, the Japanese Industrial Standard JISI.4208-1992 "Finished Men's Suits" was adopted by reference. This revision will expand the scope of application to woolen clothing such as men's suits and coats, cancel the 5.3 series and other contents, add the main contents such as the limit of formaldehyde content, color fastness regulations, pilling regulations, composition and content regulations, and supplement the contents of defect determination. Major changes have also been made in other technical contents. Appendix A of this standard, the test method for the degree of seam disengagement, partially adopts the provisions of FZ/T20019-1999 "Test method for the degree of seam disengagement of wool woven fabrics".
Appendix A of this standard is the appendix of the standard.
This standard shall be implemented from February 1, 2002. From the date of implementation, this standard will also replace GB/T2664-1993. This standard was proposed by the former State Textile Industry Bureau. This standard is under the jurisdiction of the National Technical Committee for Clothing Standardization. This standard was drafted by the Shanghai Garment Research Institute, the National Garment Quality Supervision and Inspection Center (Shanghai), and Beijing Garment Quality Supervision and Inspection Station 1. Shanshan Co., Ltd., Baoxiniao Group Co., Ltd., Fapai Fashion Design Institute, Ningbo Romon Group, Zhuangji Group Co., Ltd., Jiangsu Dacang Group and other units participated in the drafting. The main drafters of this standard are: Xu Jian, Xu Yunbao, Hu Liling, Jiang Yanxiang, Lin Yuemei, Ye Qinglai, Dai Zenghui, and Lu Huiping. 244

The quality grade of finished products is based on the existence and severity of defects. The individual products in the sampled samples are graded according to the number of defects and their severity, and the batch grade is divided according to the number of individual products in the sampled samples. 5.2.1 Defects
A single product that does not meet the technical requirements specified in this standard constitutes a defect. According to the degree of non-compliance of the product with the standard and the impact on the performance and appearance of the product, defects are divided into three categories; a) Serious defects
Defects that seriously reduce the performance of the product and seriously affect the appearance of the product are called serious defects. h) Serious defects
Do not seriously reduce the performance of the product or seriously affect the appearance of the product. However, the defects that are more serious and do not meet the requirements of the standard are called major defects.
