Some standard content:
FZ/T62007-2003
This standard is formulated according to the principles of standard formulation in the WTO/TBT agreement and the actual needs of product performance and application. This standard replaces FZ/T62007-1994 "Bed Sheets". The main changes of this standard compared with the original standard are as follows: the density index is cancelled and replaced by the unit area quality deviation rate index; the breaking strength is uniformly assessed regardless of the warp and weft directions; the washing size change rate is uniformly assessed regardless of the process, and the index has been improved; the pilling performance index of superior products is added; the color fastness is uniformly assessed regardless of dyes, and the light resistance and sweat resistance index are added; the fiber content deviation index is added;
a critical assessment sampling table is added.
The superior products of this standard are equivalent to the international advanced level, the first-class products are equivalent to the international general level, and the qualified products are equivalent to the domestic general level. Appendix A of this standard is an informative appendix.
This standard is proposed by the China National Textile and Apparel Council. This standard is under the jurisdiction of the China Home Textile Standardization Technical Management Unit. The drafting units of this standard are: Jiangsu Fiber Inspection Institute (Jiangsu Textile Product Quality Supervision and Inspection Center), Jiangsu Hongliu Sheet Group, Jiangsu Menglan Group Co., Ltd., and Jiangsu Tanghuang Group. The main drafters of this standard are: Xu Xiaofeng, Liu Peijuan, Qian Yuebao, Jing Yutang, and Li Hui. The previous versions of the standards replaced by this standard are: -ZBW57002—1986, FZ/T62007-—1994. I
