HG/T 3089-2001Rubber mixture of O-ring seals for fuel (English PDF)

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 & Plastics Institute,

and Chongqing Changjiang Rubber Plant and Liaoning Tieling Research & 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.

labeling, packaging, and storage of O-ring rubber seal materials for petroleum-based fuel

system.

This Standard applies to O-ring rubber seal materials used for petroleum-based fuel

system under -40~100°C.
