This standard is equivalent to the Japanese Industrial Standard JIST8116--1998 "Labor Health Protection Gloves" to revise the recommended chemical industry standard HG/T2584--1994 "Rubber Industry Gloves". The main technical differences between this standard and JIST8116-1996 are: the industrial gloves, including rubber gloves and plastic gloves, are mainly used for protection against handling harmful chemical materials, and are changed to natural latex as the main material, suitable for labor protection used in industry, agriculture, forestry, animal husbandry, fishery, etc. The pinhole test was changed from the method of inflating and immersing in alkali solution to the method of directly filling with water to detect pinholes. - The definition of palm width, the length measured from the base of the index finger to the base of the little finger, was changed to the horizontal width at the base of the thumb. The test method for puncture resistance was not adopted.
- The index of tensile load was changed from 80N/cm to 100N/cm. The main technical differences between this standard and HG/T25841991 are: - The specifications and sizes were changed from four specifications of extra large, large, medium and small, and there were index requirements for the length of the middle finger and the thickness of the single layer, to three models of large, medium and small, and no requirements were made for the length of the middle finger and the thickness of the single layer. Appendix B was added.
- The test method for permeation resistance is specified.
Appendix A and Appendix B of this standard are both appendices of the standard. This standard will replace HG/T2584-1994 from the date of implementation. This standard was proposed by the Policy and Regulations Department of the former State Bureau of Petroleum and Chemical Industry. This standard is under the jurisdiction of the Latex Products Sub-Technical Committee of the National Rubber Standardization Committee. The drafting unit of this standard: Zhuzhou Rubber and Plastics Industry Research and Design Institute of China Rubber Group. The main drafters of this standard: Tan Yunhua and Li Meihui. This standard was first issued in 1963 as the Ministry of Chemical Industry Standard HGB4075-1963, revised in 1982 as the Ministry of Chemical Industry Standard IIG41455-82, and revised in 1994 as the recommended chemical industry standard HG/T2584-1994. This is the third revision. 1

When testing the finished product, there shall be no significant expansion, contraction, hardening, etc., and it shall not hinder the movement of fingers. 5 Test method
5.1 Appearance inspection
Inflate the gloves and inspect visually without expanding them. 5.2 Size measurement
The total length of the gloves refers to the length from the tip of the middle finger to the edge of the sleeve in the hanging direction, and the palm width refers to the length measured horizontally at the base of the thumb. When measuring, flatten the product and measure it with a millimeter scale under the condition that the gloves are under pressure. 5.3 Tensile load
5.3.1 Use the I-type cutter specified in GB/T528 to cut the sample from the back, wrist and palm smooth surface of the glove along the immersion square. 5.3.2 The tensile load shall be measured according to the method specified in GB/T528 and calculated according to formula (1): above
where: L
-tensile load, N/cm;
maximum load, N;
B-the width of the working part of the sample, cm.
5.4 Pinhole test
