1、Designation: D6046 02 (Reapproved 2012)D6046 17Standard 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

3、sification establishes categories 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 cla

4、ssification the aspects of environmental impact included are environmental persistence ofwhich biodegradability is one component and acute ecotoxicity. Although environmental persistence is discussed first, thisclassification does not imply that considerations of environmental persistence should tak

5、e precedence over concerns forecotoxicity.1.4 Another important aspect of environmental impact is bioaccumulation. 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 ad

6、dresses the fresh water and soil environmental compartments.At this time marine and anaerobicenvironmental compartments 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 compar

Theclassification is not intended to address environmental impact in situations of major, accidental release. Nothing in thisclassification should be taken to re

It is the responsibilityof the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.1.9 This international standard was developed in accordance wit

49、ndard Definitions,1990 or Terminology E943.4. Significance and Use4.1 This classification establishes categories of hydraulic fluids which are distinguished by their response to certain standardizedlaboratory procedures. These procedures indicate the possible response of some environmental compartments to the introductionof the hydraulic fluid. One set of procedures measures the aerobic aquatic biodegradability (environmental persistence) of the fluidsand another set of procedures estimates the acute ecotoxicity effects of the fluids.4.
