This standard replaces "Injection Molding Shoes" (HG/T 3084-1991).
The main technical changes in this standard over "Injection Molding Shoes" (HG/T
3084-1991) are as follows.
- Net items were added in product classification;
- The item “flexing resistance” of finished shoes was added;
- The item “discoloration resistance” was added;
- Items of tensile strength, elongation at break and hardness inspection were deleted;
- Parts of requirements on appearance quality were modified;
- The provision "Defects that may affect wearing shall not exist" was added in
appearance quality requirements;
- The name of “cold resistance” was changed into “cut increasing resistance”;
- Methods for cold resistance test were adjusted.
This standard was proposed by China Petroleum and Chemical Industry Association.
This standard shall be under the jurisdiction of the Subcommittee on Rubber Shoes the
National Technical Committee on Rubber & Products of Standardization Administration of
China (SAC/TC 35/SC9).
Drafting organizations of this standard. Fujian Footwear Products Quality Supervision and
Inspection Center, and Fujian Jinjiang Yuantong Shoe Co., Ltd.
Chief drafting staffs of this standard. You Yongyi, Xu Chunshu, Cai Hongshan, Li Jianjia, and
Li Huawei.
Previous editions of the standard replaced by this standard are.
- HG/T 3084-1989;
- HG/T 3084-1999.
Injection Molding Shoes
1 Scope
This standard specifies the classification, requirements, test methods, inspection rules and
marking, packing, transportation and storage of injection molding shoes.
This standard is applicable to common shoes made by injection molding process with
thermoplastic elastomer SBS, PVC and modified PVC as sole materials, and synthetic or
natural materials as upper materials.

3 Classification
Injection molding shoes are classified according to outsole materials.
a) Injection molding shoes with thermoplastic elastomer SBS soles;
b) Injection molding shoes with PVC soles;
c) Injection molding shoes with dense-type modified PVC soles;
d) Injection molding shoes with foamed modified PVC soles.
4 Requirements

Prepare 2 test blocks with the length of (40±3)mm, width of (10.0±0.2)mm and thickness of
(2.0±0.3)mm according to the methods in HG/T 2198-1991. Place them in a dryer with
calcium chloride or silica gel. Measure its mass 24h later. Then place the 2 test blocks in an
air thermotank at (100±2)°C and keep them for 6h. Transfer them into a dryer and keep for 1h.
Then measure the mass.
The heating loss H (%), expressed by mass fraction, shall be calculated according to Formula
(1). And the test result shall take the average value.
