HB 5229-1983 (English Version) PDF

Scope: The standard stipulates the quality requirements for low compression permanent deformation fluororubber for aviation and can be used as the basis for inspection by production and use departments. The rubber compounds specified in this standard are mainly used for manufacturing movable and fixed seals working in air, petroleum-based lubricants, fuel and hydraulic oils, silicate and diester synthetic lubricants. In addition to good media resistance, this rubber also has the characteristics of low compression permanent deformation. The working temperature is generally -40~250℃. For some parts of use, the temperature can be lower than -40℃ or higher than 250℃.
