1、Designation:D604618Standard Classification ofHydraulic Fluids for Environmental Impact1This standard is issued under the fixed designation D6046;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in pa
2、rentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This classification covers all unused fully formulatedhydraulic fluids in their original form.1.2 This classification establishes categories for the i
3、mpactof hydraulic fluids on different environmental compartments asshown in Table 1.Fluids are assigned designations within thesecategories;for example PwL,Pwe,and so forth,based onperformance in specified tests.1.3 This classification includes environmental persistenceand acute ecotoxicity as aspec
4、ts of environmental impact.Although environmental persistence is discussed first,thisclassification does not imply that considerations of environ-mental persistence should take precedence over concerns forecotoxicity.1.3.1 Environmental persistence describes long term impactof hydraulic fluids to th
5、e environment.Environmental persis-tence is preferably measured by ultimate biodegradation butcan also be measured by other means.1.3.2 Acute toxicity describes the immediate toxic impact ofhydraulic fluids to the environment.Acute toxicity is prefer-ably measured by the three trophic levels of aqua
6、tic organisms(Algae,Crustacea,and Fish).1.4 Another important aspect of environmental impact isbioaccumulation.This aspect is not addressed in the presentclassification because adequate test methods do not yet exist tomeasure bioaccumulation of hydraulic fluids.1.5 The present classification address
7、es the fresh water andsoil environmental compartments.At this time marine andanaerobic environmental compartments are not included,al-though they are pertinent for many uses of hydraulic fluids.Hydraulic fluids are expected to have no significant impact onthe atmosphere;therefore that compartment is
8、 not addressed.1.6 This classification addresses releases to the environmentwhich are incidental to the use of a hydraulic fluid.Theclassification is not intended to address environmental impactin situations of major,accidental release.Nothing in thisclassification should be taken to relieve the use
9、r of theresponsibility to properly use and dispose of hydraulic fluids.1.7 This classification does not cover any performanceproperties of a hydraulic fluid which relate to its performancein a hydraulic system.1.8 This standard does not purport to address all of thesafety concerns,if any,associated
10、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.1.9 This international standard was developed in accor-dance with internationally recognized p
