1.1This specification covers performance requirements for biodegradable hydraulic fluids with low aquatic toxicity used in industrial/mobile hydraulic applications.

1.2In some cases, biodegradable fluids have been found to perform differently than traditional mineral oils, thus separate performance requirements are desirable.

1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
