This standard layer This standard JISS500:-1992 is a non-equivalent standard for the revision of the recommended chemical industry standard HG/20201991 "Colored Shoes (temporary)". The main technical differences of this standard 115S5005-1992 are the deformation, cold resistance, addition and reduction (existence), fabric properties, dyeing rate and other performance indicators in the industrial standard. A detailed description of the appearance quality is given. The main technical differences of this standard HG/2020-1951 are ：- The tensile strength aging performance retention rate has been added as a type test item. The rubber (skin) and outer sole thickness requirements and water resistance test requirements have been added. For the external quality inspection, the use of (B26U& color change evaluation color sample card as the color difference evaluation period has been added. From the date of implementation, this standard will replace HG/T202).-1931 This standard was proposed by the former State Petroleum and Chemical Industry Bureau. This standard is issued The National Standardization Technical Committee for Rubber and School Products is under the jurisdiction of the Rubber Fusion Technical Committee. The parties involved in this standard are: the National Bureau of Exit and Entry Inspection and Quarantine of the People's Republic of China, Jiangsu Shuangshi Shoes Co., Ltd. The main drafters of this standard are: Fei Yue, Sun Changqing, Tu Wuxian, Lai Chong, Yang Laliang. This standard was first published in 1597.

6 Test method is suitable for
HG/T2020-2001
6.1 General requirements for the test method of vulcanized rubber cavity type resistance performance test method are in accordance with the requirements of TIG Ting 2198, and the finished product sample can be cut along the outer bottom.
6.2 Test conditions for rubber samples
The test objects of rubber samples shall be carried out in accordance with the provisions of CB/T2941, and the effective time of the sample before the test shall not be less than 6bh. 6.3 Determination of tensile properties of vulcanized rubber
The tensile properties of vulcanized rubber are determined in accordance with GB/T523. The outer and upper surfaces of the shoe are all tested using 6-gauge cutting tools. When the specimen thickness does not meet the requirements of the test method standard: the actual thickness of the test piece is tested. 6.4 Determination of the wear resistance of vulcanized rubber
The wear resistance of vulcanized rubber is determined in accordance with GB/T1689. When the test piece is not long enough, it can be overlapped in the outer direction. When the test strength does not meet the test evaluation standard, the actual thickness of the test piece is changed for testing. 6.5 Physical change test
The hardness test is carried out in accordance with R/T3. If the thickness of the test piece does not meet the requirements, it can be stacked until the test strength requirements are met.
6.6 Intermittent strength test
The adhesion strength test is carried out according to H/T538. Sample location: Take two pieces of shoes, and collect them in two directions. The width is 10mm, and the length is 100-200mm. Cut the test piece along the effective width of the sample to 40~b0mm (that is, the effective test length of the sample>). Then use a knife to cut the test piece (shoe) from the rubber along the effective width of the sample. 6.7 Transfer elongation test
6. 7. 1 Test piece
Cut a test piece with a length of 120~125mm and a width of (1C ± 0.2)mm, which is the thickness of the original finished product, and mark two marking lines with a distance of (100 ± (.5)Trum on the finished piece
6.7.2 Test steps
After adjusting the clamps of the tensile machine so that the distance between them is 100, the test piece is precisely controlled under the test conditions, and the lowering speed of the head holder is <10)-10)mm/min. When the test piece is stretched to 7 degrees and the first crack appears, it is tested. Make two tests for each pair (load) and take the average value.
6.7.3 The result shows that the film elongation rate is calculated in %) according to formula (1),
is the distance between the original marking lines of the film, m
where: 1.
When the first crack appears on the aging film, the distance between the marking lines is mm. 6.8 Aging test
Perform according to the provisions of GR/T5512. The aging test conditions are (7C+1)℃×72h. The aging time is 4-24b. The index strength after aging is measured and compared with the unaged test piece to calculate the aging performance retention rate P[must]: The tensile strength aging performance retention rate PI%1 is calculated according to formula (2): Px100
Wherein: A—tensile strength of the sample after aging, MPa1(); tensile strength before aging, MI\a,
Aging performance retention rate () value. Accurate to the desired digit. (2)
6.9 Determination of the degree of corrosion
6.9.1 Determination of external corrosion resistance
HG/T2020
Take the outer bottom of the sample, scratch the edge of the outer point, and separate it from the core to obtain the (sexual) base glue! , the thickness of the rubber surface is measured by the vernier scale, and the thickness of the most important point is taken as the thickness of the previous paragraph, followed by the recommended value, and the thickness of the most important point. The minimum value is taken and the decimal point is retained.
6.9.2 Determination of the thickness of the boot (carrier) surface
Cut the construction (station) surface from the test boot (frog), and obtain the (wang) Li rubber rise: Ⅱ Rubber thickness measurement wine Yue (Mu) surface thickness: take the minimum value, retain one decimal point. 6.10 Water resistance test
According to the provisions of HG/T3664:
6.11 Appearance quality
Appearance quality The color difference test method of the whole batch (carrying) of the net parts shall be carried out according to the provisions of G products: 7 Inspection rules, labels, packaging, transportation, storage inspection rules, labels, packaging, transportation, and other regulations of H/2-03 for rubber soles and rubber shoes. The outer sole thickness test shall be carried out according to 3.2.1.2 of TIG/T2403-792, and the aging test and water resistance test shall be carried out according to T1G/T2103--15923.9. Each pair of packaging shall have a standard number, 23
