31、 for Volatility Measurement1This standard is issued under the fixed designation D5842; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuper
32、script epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This practice covers procedures and equipment forobtaining, mixing, and handling representative samples ofvolatile fuels for the purpose of testing for compliance with thestandards set forth for volati
33、lity related measurements appli-cable to light fuels.1.2 The applicable dry vapor pressure equivalent range ofthis practice is 13 kPa to 110 kPa (2 psia to 16 psia).1.3 This practice is applicable to the sampling, mixing, andhandling of reformulated fuels including those containingoxygenates. This p
34、ractice is not applicable to crude oil. For thesampling of crude oil, refer to Practice D4057/API MPMSChapter 8.1, Practice D4177/API MPMS Chapter 8.2, andPractice D8009/API MPMS Chapter 8.5.1.4 The values stated in SI units are to be regarded as thestandard except in some cases where drawings may s

It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and
36、 deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-m
