[IG/T2019 —2001
This standard is not equivalent to the Japanese T industry standard JISS5005-1992 and the T/T2019—1991 (shoes). The main technical differences between this standard and J1555005-:992 are: the deformation, resistance, heating loss (%), acid cracking intensity, dyeing fastness and other performance measures in the Japanese wood industry standard are adopted.
Specific descriptions are made on the appearance.
The main technical differences between this standard and HG/2019—1991 are that the physical performance has added the frequency of pulling and the aging performance retention rate as the type inspection items, and the water performance test requirements for the upper leather and outer sole thickness of rubber boots (shoes) have been added. The external quality inspection standard is appropriately modified.
This standard replaces HG/19-1991 standard of the State Petroleum and Chemical Industry Administration from the date of implementation. This standard is under the jurisdiction of the National Rubber and Rubber Products Standardization Technical Committee Rubber Shoes Technical Committee. The responsible drafting unit of this standard: Jiangning Shenfu Rubber Factory The drafters of this standard are Hao Zengmao, Xie Hua, Chen Shi, Ding Yuchan. This standard was first issued in June 1991.

The value of aging energy retention rate (Xing) shall be accurate to 6.9 Determination of thickness
6.9.1 Determination of outer sole thickness
Retract the outer sole at the test point, cut off the outer sole edge, and leave the midsole and center core to obtain the boot sole. Determine along the center axis of the rubber sheet of the sole, use a vernier caliper to measure the thickness of the front palm force point, the back palm force point and the thickness of the bottom plate respectively, and take the maximum value of the obtained data, retaining one decimal place. 6.9.2 Determination of thickness
Cut the surface with the test piece, and separate it. When the film is obtained, use a rubber measuring device to measure the surface thickness, and take the minimum value, and retain one decimal place.
6.10 Test
The water resistance test shall be carried out in accordance with the provisions of HG/T3E64. 7 Inspection rules, marking, packaging, transportation and storage. Marking, packaging, transportation and storage shall be in accordance with the relevant provisions of HG/T2403 for the batch (shoes). The inspection of the outer thickness shall be in accordance with 3.2.1.2 of HG/T2403-7992. The aging test and micro-bearing test shall be in accordance with 3.3 of HG/T2403-1992. At the same time, the standard number 16 shall be marked on the packaging of each pair of (shoes).6 Adhesion strength test
Adhesion resistance strength test According to the environment of T532, take the test piece from the test rod: take two waists, about the longitudinal direction of the two sides, take a test rod, effective width is 1C, length 100--150mm, use a small sample to increase the effective width of the cloth and the opening, from the grid test support system vertically cut 40--50 length (that is, the effective length of the sample), 6.7 Continuous film elongation test
6.7. 1 Test piece
Cut a piece with a length of 120~125mm, a width of (10±0.2)mm, and the original thickness of the finished product, and mark the test piece with two marks with a spacing of (100-0.5)um.
6.7.2 Test step
After the whole test piece is stretched to the bottom of the holder, the test piece is accurately loaded under the holder at a speed of (100±i)mm/ia. When the test piece is stretched to the point where the paint film appears and the first bag appears, the test drill ends. 6.7.3 The result indicates that
the film length is calculated according to the sieve.
In the formula, the test piece is about the distance from the original mark line to the test piece. HG/T 2019 2001
I. When a crack appears on the film, the distance between the test piece cup lines is m: Two test pieces are made for each pair of shoes, and the average value is taken. 6.8 The overall chemical test is carried out according to B512. The aging test conditions are 70°C × 72°C. After aging, the sample is placed for 424 hours and then the tensile strength is measured. It is compared with the unaged test piece to calculate the tensile strength retention rate (%) of the tensile aging performance. The tensile strength retention rate (%) of the tensile aging performance is calculated according to (2): p
Where: A
Aging time of the sample, MPa; C Tensile amplitude of the sample before aging, MPa.
