1、Designation: D 1296 01 (Reapproved 2007)Standard Test Method forOdor of Volatile Solvents and Diluents1This standard is issued under the fixed designation D 1296; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last rev
2、ision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This test method covers a comparative proce
3、dure forobserving the characteristic and residual odors of volatileorganic solvents and diluents to determine their odor accept-ability in a solvent system.1.2 It is not intended that this test method be employed todetermine subtle odor differences between materials or todetermine odor intensity.1.3
4、 It is recommended that this test method not be employedto determine the residual odor of a liquid if its time forevaporation to dryness at room temperature exceeds 30 min oras agreed upon.1.4 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in
5、thisstandard.1.5 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 standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use. F

Reference Standards2.1 Samples of the particular products being tested, havingodor characteristics satisfactory to purchaser and manufacturer,are required.3. Signifi
7、cance and Use3.1 The comparative odor characteristics can be used, com-bined with other tests, for product identification and assessingcompliance with a specification.3.2 The residual odor characteristics can be used to judgethe presence of relatively nonvolatile materials that may beassociated with
8、 manufacture or contamination during distribu-tion. Since volatile solvents and diluents are used in a widevariety of chemical processes and residual materials may affectthe efficiency of such processes, this test method provides acomparative test for manufacturing control and assessingcompliance wi

Takespecial precautions while determining the odor of all products.Make the tests only as frequently as is necessary for controland base the evaluations on short sniffs, inhaling as little vaporas possible.4.2 Provid

These may be, butare not limited to, flammable, combustible, corrosive, orexplosive hazards.5.
11、Procedures5.1 Characteristic OdorDip 25 by 75-mm strips of rapidqualititive paper, free of foreign odor, to a depth of 50 mm intothe specimen and the reference standard, each contained in abeaker or other suitable container. Make an immediate com-parison between the odor of the two materials on the
12、filterpapers.5.2 Residual OdorDip 25 by 75-mm strips of a rapidqualitative paper, free of foreign odor, to a depth of 50 mm intothe specimen under test and the reference sample, eachcontained in a beaker or other suitable container. Permit thepapers to dry in air at room temperature and examine them

Report the odor as “residual” if anodor persists on the sample paper after none is detectable onthe standard paper.7. Precision and Bias7.1 PrecisionS
18、ince the result of the test is merely asubjective judgment of whether there is comparative similaritywith the reference standard specified in the procedure, nostatement is made about the precision of assessing eithercharacteristic or residual odor.7.2 BiasNo statement is made about the bias of eithe

In either case, the accuracy of odor measurementsshould be considered suspect. In case of differing resu

Consider-ation should be given to the qualifications of the panelists, suchas the following: familiarity with odor determinations, lengthof time exposed to either the main or suspect
