1、Designation: D6046 02 (Reapproved 2012)Standard 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
2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification covers all unused fully formulatedhydraulic fluids in their original form.1.2 This classification estab
3、lishes categories for the impactof 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 In the current version of this classification the as
4、pects ofenvironmental impact included are environmental persistenceof which biodegradability is one component and acute ecotox-icity.Although environmental persistence is discussed first, thisclassification does not imply that considerations of environ-mental persistence should take precedence over
5、concerns forecotoxicity.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 addresses the fresh wa
6、ter 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 not address
7、ed.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 user of ther

Significance and Use4.1 This classification establishes categories of hydraulicfluids which are distinguished by
46、their response to certainstandardized laboratory procedures. These procedures indicatethe possible response of some environmental compartments tothe introduction of the hydraulic fluid. One set of proceduresmeasures the aerobic aquatic biodegradability (environmentalpersistence) of the fluids and an
47、other set of procedures esti-mates the acute ecotoxicity effects of the fluids.4.1.1 Although this classification includes categories forboth persistence and ecotoxicity, there is no relationshipbetween the two categories. They may be used independentlyof each other, that is, a hydraulic fluid can b
48、e categorized withrespect to both sets of laboratory procedures, or to persistencebut not ecotoxicity, or to ecotoxicity but not persistence.4.1.2 There is no relationship between the categoriesachieved by a hydraulic fluid for persistence and for ecotoxic-ity. The placing of a hydraulic fluid with
49、regard to one set ofcategories has no predictive value as to its placement withregard to the other set of categories.4.2 The test procedures used to establish the categories ofhydraulic fluids are laboratory standard tests and are notintended to simulate the natural environment. Definitive fieldstudies capable of correlating test results with the actualenvironmental impact of hydraulic fluids are usually sitespecific and so are not directly applicable to this classification.Therefore, the categories established by this classification canserve
