This specification covers performance requirements for biodegradable hydraulic fluids with low aquatic toxicity used in industrial/mobile hydraulic applications. There are some cases where biodegradable fluids have been found to perform differently than traditional mineral oils, which makes separate performance requirements desirable.

Also included in this specification are requirements for environmental behavior and physical properties as well as compatibility of mixtures of hydraulic fluids.

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

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

1.3 This 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.
