1、Designation:D802918Standard Specification forBiodegradable,Low Aquatic Toxicity Hydraulic Fluids1This standard is issued under the fixed designation D8029;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A nu
2、mber in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers performance requirements forbiodegradable hydraulic fluids with low aquatic toxicity usedin industrial/mobile hydr
3、aulic applications.1.2 In some cases,biodegradable fluids have been found toperform differently than traditional mineral oils,thus separateperformance requirements are desirable.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard
4、.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5
