1、Designation:D129601(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 revision.A
2、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 procedure forobserv
3、ing 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 is recomme
4、nded 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 thisstandard.1.
5、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 specific hazards
