Foreword
On the basis of QB 1002-1997 "Vulcanized Leather Shoes", QB/T 1004-1990 "Sewing
Leather Shoes" and QB/T 1005-1990 "Mould Pressing Leather Shoes", this standard
integrates leather shoes manufactured with various processes into one standard.
Main revised contents of this standard include.
— Standard name;
— Extend application scope;
— Change the description method of technical requirements;
— Delete thickness recommended value of main components;
— Change the appearance quality to sensory quality. And carry out additions, deletions
and modifications to some inspection items;
— Carry out adjustment to indexes of physical and mechanical properties;
— Add requirements of low temperature flexing resistance of upper materials;
— Add provision “defects which may affect wearing shall not exist” in the technical
requirements;
— Change the description method of inspection rules.
Appendix A of this standard is informative.
This standard was proposed by the China National Light Industry Council.
This standard shall be under the jurisdiction of Nationwide Standardization Center of
Shoemaking.
Drafting organizations of this standard. China Leather and Footwear Industry Research
Institute, Jiangsu Senda Co., Ltd., Kangnai Group Co., Ltd., Shishi Fulin Shoe Industry Co.,
Ltd., Ligang Shoe Industry (Shenzhen) Co., Ltd., and Aokang Group Co., Ltd.
Chief drafting staffs of this standard. Yan Huaidao, Qi Xiaoxia, Zhu Xianggui, Zheng
Xiukang, Lin Heping, Sheng Baijiao, and Wang Zhenquan.
The previous editions of the standard replaced by this standard are.
— QB/T 1002-1990, QB 1002-1997;
— QB/T 1003-1990;
— QB/T 1004-1990;
— QB/T 1005-1990.
From the implementation date of this standard, it shall abolish the previous light industry
standard QB 1002-1997 "Glueing Leather Shoes" issue by China National Council of Light
Industry. And it shall replace light industry standards QB/T 1003-1990 "Vulcanized Leather
Shoes", QB/T 1004-1990 "Sewing Leather Shoes", and QB/T 1005-1990 "Mould Pressing
Leather Shoes" issued by former Ministry of Light Industry.
Introduction
It has been fourteen years since the issuance and implementation of standards QB/T
1003-1990 "Vulcanized Leather Shoes", QB/T 1004-1990 "Sewing Leather Shoes"
and QB/T 1005-1990 "Mould Pressing Leather Shoes". And it has been seven years
since the issuance and implementation of QB 1002-1997 "Glueing Leather Shoes".
Over the years, product styles of leather shoe have been updated continuously;
product quality has been continuously improved; and plenty of changes occur in raw
and auxiliary materials and manufacture process. Therefore, standard revision is
urgently needed in order to adapt to the industry development and product
requirements. This standard integrates leather shoes manufactured with various
processes into one standard, on the basis of QB 1002-1997 "Vulcanized Leather
Shoes", QB/T 1004-1990 "Sewing Leather Shoes" and QB/T 1005-1990 "Mould
Pressing Leather Shoes".
Leather Shoes
1 Scope
This standard specifies the requirements, test methods, inspection rules, marking, packing,
transport and storage of leather shoes manufactured with various processes.
This standard is applicable to ordinary wearing leather shoes (including boots) with upper
fabric made of natural leather, artificial material, etc.
This standard is not applicable to footwear of safety, protection and specific functions.

3 Classification
According to using objects, shoes are divided into shoes for men, women and children.
According to upper materials, shoes are divided into shoes with natural leather (top-layer
leather and second-layer leather of animals such as pig, cattle and sheep) and artificial
material upper.
According to manufacturing process, shoes are divided into the following categories. glueing,
sewing, mould pressing, vulcanized, injection molding, filling, etc.
