This standard is developed in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by China Machinery Industry Federation. This standard is under the jurisdiction of National Technical Committee on Hydropneumatic of Standardization Administration of China (SAC/TC 3). Rotary shaft lip-type seals - Determination of friction torque 1 Scope This standard specifies the determination method of friction torque of rotary shaft lip-type seals. This standard is applicable to determining the friction torque of rotary shaft lip-type seals (hereinafter referred to as seals). 2 Normative references The following referenced documents are indispensable for the application of this standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
