Standard Classification of
1
Hydraulic Fluids for Environmental Impact
This standard is issued under the fixed designation D6046; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision.Anumber in parentheses indicates the year of last reapproval.A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

bility of regulatory limitations prior to use.

hydraulic fluids in their original form.
