Причина отмены This specification covered performance classifications for biodegradable fire-resistant hydraulic fluids that are used in the industrial/mobile and mining industries.

Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this specification was withdrawn in January 2024 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Реферат

This specification presents the performance classifications for biodegradable fire-resistant hydraulic fluids that are used in the industrial/mobile and mining industries. Covered here are seven material classes, as follows: HFA are fire resistant hydraulic fluids that may be further classified as HFAE, which are oil-in-water emulsions, and HFAS, which are chemical solutions not containing any emulsions; HFB, which are water-in-oil emulsions; HFC, which are aqueous monomer and polymer polyglycol solutions; HFD, which are phosphate ester or polyolester-based, water-insoluble fire-resistant fluids; HFDR, which are phosphate ester-based fluids; HFDU, which arewater-free fluids based on chemical compounds other than phosphate esters and chlorinated hydrocarbons; and HEPG, which are anhydrous "environmentally friendly" polyalkylene glycol-derived hydraulic fluids that may be water soluble or insoluble.
