This standard is drafted in accordance with the rules given in the GB/T 1.1-2009.
This standard is a revision to the GB/T 15107-2005 Athletic shoes. The main differences compared with GB/T 15107-2005 are:
--Revised application scope of standard;
--Revised product classification;
--Deleted main component’s suggestion thickness;
--Added, deleted and revised appearance quality test items;
--Revised peeling test methods;
--Revised adhesive performance test methods;
--Revised other physical and mechanical performance requirement;
--Added the requirements of critical substance;
--Revised product judgments.
--Inspection rules and marking, packaging, transportation, storage directly adopt QB/T 1187 Footwear—principle of inspection and marking, package, transportation, storage.
Attention is drawn to the possibility that some of the elements of this standard may be the subject of patent rights. The issuing body of this document shall not be held responsible for identifying any or all such patent rights.
This standard was proposed by China National Light Industry Council.
This standard was prepared by SAC/TC 305 (National Technical Committee 305 on Footwear of Standardization Administration of China).
The previous edition replaced by this standard is:
--GB/T 15107-2005；
--GB/T 15107-1994.
