Some standard content:
Record number: 10142-2002
HG/T 3096-2001
This standard is a revision of the recommended chemical industry standard HG/T3096-1989 "Water Gate Rubber Seals". The main technical differences between this standard and HG/T3096-1989 are: the addition of S7774 and SG6574 materials.
- The requirements for tensile stress, compression modulus and density are added to the physical properties. The appearance quality of the product is more detailed. Appendix A of this standard is the appendix of the standardwwW.bzxz.Net
This standard replaces HG/T3096-1989 from the date of implementation. This standard was proposed by the Policy and Regulations Department of the former State Administration of Petroleum and Chemical Industry. This standard is under the jurisdiction of the Sealing Products Sub-Technical Committee of the National Rubber and Rubber Products Standardization Technical Committee. The drafting units of this standard are: Northwest Rubber and Plastic Research and Design Institute, Nanjing Rubber Factory, Northeast Survey and Design Institute of the Ministry of Water Resources, and the main drafters of this standard are: Gao Jingru, Sheng Gou, Su Jialin. This standard was first issued as the national standard GB10706-1989 in 1989. In 1997, it was adjusted to an industry standard and renumbered as HG/T 3096—1989 (1997),
