1、Designation: D1296 01 (Reapproved 2012)Standard Test Method forOdor of Volatile Solvents and Diluents1This standard is issued under the fixed designation D1296; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revis
2、ion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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 procedur
3、e 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 It
4、 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 thi
5、sstandard.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. For

Reference Standards2.1 Samples of the particular products being tested, havingodor characteristics satisfactory to purchaser and manufacturer,are required.3. Significan
7、ce 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 ma
8、nufacture 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 with
9、a specification.4. Hazards4.1 Many solvents and diluents are hazardous or toxic. 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 Provide a
10、dequate ventilation to maintain solvent ordiluent concentration below the personnel exposure limit valueestablished for the general work area as given in the MSDS.4.3 Other hazards may also be present. These may be, butare not limited to, flammable, combustible, corrosive, orexplosive hazards.5. Pro

Some analysts have littleolfactory sensitivity to some materials, while other analystshave extreme sensitivity to either the main or (if any) minorcomponent.

Consider-ation should be given to the qualifications of the panelists, suchas the following: familiarity with odor determinations, lengthof time exposed
21、 to either the main or suspected minorcomponent, and the environment in which the test is to beconducted.8.
