Foreword
This Standard is drafted through the revision of the recommended chemical industry standard HG/T 3089-1987 Rubber Mixture of O-ring Seals for Fuel. The main differences between this Standard and HG/T 3089-1987(1997) are as follows.
?€? Remove "Manufactured by nitrile rubber" in the scope.
?€? For compressive set test method, adopt GB/T 7759-1996 Rubber, Vulcanized or thermoplastic-Determination of compression set at ambient elevated or low temperatures. And appropriately adjust the indicators.
This Standard shall replace HG/T 3089-1987 from the implementation date. This Standard was proposed by State Bureau of Petroleum and Chemical Industry. This Standard shall be under the jurisdiction of Technical Committee for Seal Products, National Technical Committee for the Standardization of Rubber and Rubber Products. Responsible drafting organizations of this Standard. Northwest Rubber and Plastics Institute, and Chongqing Changjiang Rubber Plant and Liaoning Tieling Research and Design Institute of Rubber Industry.
Main drafters of this Standard. Cao Yuanli, Cao Xiaofeng, and Dai Yanfen. This Standard was published for the first-time as the national standard GB 7527-1987 in 1987. In 1997, it was adjusted to be the recommended chemical industry standard and was renumbered as HG/T 3089-1987.
