QB/T 2216—1996
This standard is formulated for the first time based on JISA6921--1979 "Wallpaper", with reference to its technical requirements, combined with the characteristics of needle-punched tapestries and national fire safety requirements.
The drafting and expression of this standard document is based on the requirements of GB/T1.1-1993 "Guidelines for Standardization Work Unit 1: Rules for Drafting and Expression of Standards Part 1: Basic Regulations for Standard Writing". Needle-punched tapestries are a new series of needle-punched carpets, used for indoor wall decoration, and have obvious differences in texture and decorative style from wallpaper. Therefore, in order to ensure the quality of tapestries and meet the needs of the rapid development of the modern interior decoration art market, this standard is specially formulated. This standard adopts the color fastness, breaking strength and other items in the JISA6921 standard. In order to make the product have good covering uniformity, the coefficient of variation of unit area quality is added; in order to ensure that the product has safe fire resistance, the combustion resistance item is added. Appendix A of this standard is the appendix of the standard.
This standard is proposed by the Quality Standards Department of China Light Industry Association. This standard is under the jurisdiction of the National Carpet Standardization Center. The drafting units of this standard are: Tianjin Carpet Research Institute, Tianjin Huaxin Carpet Co., Ltd., Shandong Rushan Maosheng Carpet Co., Ltd., Shandong Wendeng Decorative Fabric Factory.
The main drafters of this standard are: Zhang Yufen, Xia Jiadie, Li Xiaowen, Wang Rizhu, Guo Jinfa, Li Shuguo. 126

7 Inspection rules
Product inspection is divided into factory inspection and type inspection. 7.1 Factory inspection
7.1.1 Appearance quality should be fully inspected. 7.1.2 Intrinsic quality should be sampled for major items, coefficient of variation of mass per unit area and 45° burning performance by batch. 7.2 Type inspection
7.2.1 Type inspection should be carried out in the following cases. a) After formal production, if there are major changes in product structure, raw materials, and process conditions that may affect product performance; b) During normal production, products should be inspected periodically (generally not more than one year) after a certain amount of production has been accumulated; c) When the national quality supervision agency puts forward the requirement for type inspection. 7.2.2 Type inspection The quality of the product is sampled and inspected in batches.

7.3.1 The internal quality and appearance quality of needle punched tapestries are divided into three grades: superior, first-class and qualified. Anything below qualified is considered unqualified. 7.3.2 The intrinsic quality is graded on a batch basis (the same color, raw materials, variety and process parameters are considered a batch); the appearance quality is graded on a roll basis; the intrinsic quality and appearance quality grades are evaluated according to Table 1 and Table 2, and then comprehensively evaluated according to Table 4.

7.3.3 The quality grade of the product is determined comprehensively by its intrinsic quality and appearance quality, and the lowest grade of the intrinsic quality and appearance quality is used to determine the quality grade of the batch of products.
7.4 Judgment rules
7.4.1 In the appearance quality inspection items, if only one item is unqualified, it is allowed to double sample and re-test all items from the batch of products. If the re-test is qualified or better than qualified, the appearance quality of the batch of products is judged to be qualified; if there is still one roll unqualified, the batch of products shall be re-classified according to Table 2. 7.4.2 In the internal quality test items, if only one item is unqualified, it is allowed to double sample and re-test the unqualified item of the product. If the re-test is qualified or better than qualified, the internal quality of the product is judged to be qualified; if it is still unqualified, the batch of products shall be judged as unqualified products. 8 Marking, packaging, transportation, storage
