1、Designation: D6046 17D6046 18Standard 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.

2、A number 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 classification covers all unused fully formulated hydraulic fluids in their original form.1.2 This classification establishes c

3、ategories for the impact of hydraulic fluids on different environmental compartments asshown in Table 1. Fluids are assigned designations within these categories; for example PwL, Pwe, and so forth, based onperformance in specified tests.1.3 In the current version of this classification the This cla

4、ssification includes environmental persistence and acute ecotoxicityas aspects of environmental impact included are environmental persistence of which biodegradability is one component and acuteecotoxicity. impact. Although environmental persistence is discussed first, this classification does not i

5、mply that considerations ofenvironmental persistence should take precedence over concerns for ecotoxicity.1.3.1 Environmental persistence describes long term impact of hydraulic fluids to the environment. Environmental persistenceis preferably measured by ultimate biodegradation but can also be meas

6、ured by other means.1.3.2 Acute toxicity describes the immediate toxic impact of hydraulic fluids to the environment. Acute toxicity is preferablymeasured by the three trophic levels of aquatic organisms (Algae, Crustacea, and Fish).1.4 Another important aspect of environmental impact is bioaccumula

7、tion. This aspect is not addressed in the presentclassification because adequate test methods do not yet exist to measure bioaccumulation of hydraulic fluids.1.5 The present classification addresses the fresh water and soil environmental compartments.At this time marine and anaerobicenvironmental co

8、mpartments are not included, although they are pertinent for many uses of hydraulic fluids. Hydraulic fluids areexpected to have no significant impact on the atmosphere; therefore that compartment is not addressed.1.6 This classification addresses releases to the environment which are incidental to

9、the use of a hydraulic fluid. Theclassification is not intended to address environmental impact in situations of major, accidental release. Nothing in thisclassification should be taken to relieve the user of the responsibility to properly use and dispose of hydraulic fluids.1.7 This classification

10、does not cover any performance properties of a hydraulic fluid which relate to its performance in ahydraulic system.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate

11、 safety, health, and environmental practices and determine the applicability ofregulatory limitations prior to use.1.9 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of
