Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This standard replaces GB/T 14272-1993 "Down Garments". Compared with GB/T 14272-1993, this standard has the following major changes: ——Technical requirements related to the accessories and appearance quality requirements were added; ——Down quantity of finished product garment was improved from "not less than 45%" to "not less than 50%"; ——Allowable deviation of down-filling quantity of finished product garment was -5%; ——The inspection requirements for the microorganism state (mesophilic aerobic bacteria, streptococcus faecalis, sulfurous acid reduced clostridium and salmonella) of feather and down were added; ——"The color difference between top and trouser in a suit shall not be less than Grade 3~4" was added; ——Requirements for the colour fastness to washing, color fastness to wet friction and colour fastness to light were added; ——Formaldehyde content released from the finished product ≤300mg/kg was added; ——Requirements for the allowable degree of pH value of finished product 4.0 ~ 9.0 were added; ——Sample single piece judgment requirements were improved; ——Contents of down garments finished product defect judgment were supplemented and consummated; ——Appendix C "Testing method of down-filling quantity" was added. Appendix A "Test Methods for Slipping Degree of Seam" of this standard adopts by reference to the provisions in FZ/T20019-1999 "Test Method for Determining the Seam Slipping of Wool Woven Fabrics". Appendix A, Appendix B and Appendix C of this standard are normative. This standard was proposed by China National Textile and Apparel Council. This standard is under the jurisdiction of the National Technical Committee 219 on Garments of Standardization Administration of China. Shanghai Garment Research Institute, National Garments Quality Inspection and Supervision Center (Shanghai) are Professional Committee of China's Down Products are responsible for drafting this standard. Jiangsu Kangbo Group Co., Ltd. is participating in drafting this standard. Chief drafting staffs: Xu Jian, Xu Yunbao, Zhou Xipu, Chen Lu, Zheng Jinyang, Qin Wei, Gao Dekang. This standard was issued for the first time in 1993, and this was the first revision. Down Garments 1 Scope This standard specifies the requirements, inspection (testing) method, inspection classification rules as well as marking, packaging, transportation, storage and other technical features for the down garments. This standard is applicable to the mass-produced garments with textile fabrics as raw material and down as filler. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard.
