1、Designation:D641715Standard Test Method forEstimation of Engine Oil Volatility by Capillary GasChromatography1This standard is issued under the fixed designation D6417;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 test method covers an estimation of the amount ofengine oil volatilized at 371 C(700 F).1.1.1 This test method can also be
3、used to estimate theamount of oil volatilized at any temperature between 126 Cand 371 C,if so desired.1.2 This test method is limited to samples having an initialboiling point(IBP)greater than 126 C(259 F)or the firstcalibration point and to samples containing lubricant base oilswith end points less
4、 than 615 C(1139 F)or the lastn-paraffins in the calibration mixture.By using some instru-ments and columns,it is possible to extend the useful range ofthe test method.1.3 This test method uses the principles of simulated distil-lation methodology.1.4 This test method may be applied to both lubrican
5、t oilbase stocks and finished lubricants containing additive pack-ages.These additive packages generally contain high molecu-lar weight,nonvolatile components that do not elute from thechromatographic column under the test conditions.The calcu-lation procedure used in this test method assumes that a
6、ll of thesample elutes from the column and is detected with uniformresponse.This assumption is not true for samples with non-volatile additives,and application of this test method undersuch conditions will yield results higher than expected.For thisreason,results by this test method are reported as
7、area percentof oil.1.5 The values stated in SI units are to be regarded asstandard.The values stated in inch-pound units are providedfor information only.1.6 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
8、 standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D2887 Test Method for Boiling Range Distribution of Pe-troleum Fractions by Gas ChromatographyD4626 Practice for Calculati
