Significance and Use3.1 This test method describes the analytical measurementof residual matter in so
8、lvents that are intended to be 100 %volatile at 105 6 5C. Volatile solvents are used in themanufacture of paint, varnish, lacquer, and other relatedproducts, and the presence of any residue may affect theproduct quality or efficiency of the process. This test method isuseful in manufacturing control
9、 and assessing compliance withspecifications.4. Apparatus4.1 Oven, thermostatically controlled at 105 6 5C.4.2 Dish, evaporating, platinum, 125-mL. A platinumevaporating dish is preferred. Alternatively, an aluminum orporcelain dish may be used (see Note 1).NOTE 1Precision data were determined utili

Hazards5.1 WarningCertain solvents and chemical intermedi-ates, particularly, but not only ethers and unsaturated com-pounds, may form peroxides during storage. These peroxidesmay present a viole
11、nt explosion hazard when the chemicals areevaporated. When peroxide formation is likely because ofchemical type or length of storage time, analyze the materialfor peroxides (see Test Method E 299). If they exist inhazardous concentrations, take appropriate precautions such asdestroying the peroxides

16、ath or a hot plate in a fumehood and evaporate. WarningSince aliphatic hydrocarbonshave low autoignition temperatures, only efficient hoodsshould be used.NOTE 2Precision data were obtained only with evaporation usingsteam bath.6.3 Return the dish and contents to the oven for 15 to 30min, cool, and r
17、eweigh. Repeat, if necessary, until the weight isconstant to within 0.1 mg of the previous weighing.7. Report7.1 Report as nonvolatile matter the residue obtained fromthe specimen as milligrams of nonvolatile residue/100 mL.8. Precision and Bias38.1 PrecisionThe precision statements are based upon a
18、ninterlaboratory study in which one operator in each of eightdifferent laboratories analyzed one sample of methyl ethylketone in duplicate on two different days. This sample wasprepared by adding 0.006 % of a nonvolatile resin to commer-cial methyl ethyl ketone. Platinum evaporating dishes wereused
19、in this study. The results were analyzed in accordancewith Practice E 180. The within-laboratory standard deviationwas found to be 0.26 mg/100 mL, and the between-laboratoriesstandard deviation 0.71 mg/100 mL. Based upon these standarddeviations, the following criteria should be used for judging the
20、acceptability of results at the 95 % confidence level:8.1.1 RepeatabilityTwo results, each the mean of dupli-cates, obtained by the same operator on different days shouldbe considered suspect if they differ by more than 0.9 mg/100mL.8.1.2 ReproducibilityTwo results, each the mean of dupli-cates, obt
21、ained by operators in different laboratories should beconsidered suspect if they differ by more than 2.4 mg/100 mL.8.2 BiasBias can not be determined because there is noavailable material having an accepted reference value.9.

22、GESCommittee D01.35 has identified the location of selected changes to this standard since the last issue(D 1353 - 02) that may impact the use of this standard.(1) Modified 6.2 to highlight alternate evaporating dishesallowed in 4.2, as well as to allow the use of a hot plate in afume hood in evapor
23、ating the solvent.(2) Added a new Note 2.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and th
