Pour point of petroleum products -
Test method
(Second revision)
1.1 This test method covers and is intended for use on any
petroleum product.2 A procedure suitable for black specimens,
cylinder stock, and nondistillate fuel oil is described in 8.8. The
cloud point procedure formerly part of this test method now
appears as Test Method D2500.
1.2 Currently there is no ASTM test method for automated
Test Method D97 pour point measurements.
1.3 Several ASTM test methods offering alternative procedures
for determining pour points using automatic apparatus
are available. None of them share the same designation number
as Test Method D97. When an automatic instrument is used,
the ASTM test method designation number specific to the
technique shall be reported with the results. A procedure for
testing the pour point of crude oils is described in Test Method
D5853.
1.4 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.5 WARNING—Mercury has been designated by many
regulatory agencies as a hazardous material that can cause
central nervous system, kidney and liver damage. Mercury, or
its vapor, may be hazardous to health and corrosive to
materials. Caution should be taken when handling mercury and
mercury containing products. See the applicable product Material
Safety Data Sheet (MSDS) for details and EPA’s
website—http://www.epa.gov/mercury/faq.htm—for additional
information. Users should be aware that selling mercury
and/or mercury containing products into your state or country
may be prohibited by law.
1.6 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability
of regulatory limitations prior to use.
1.7 This international standard was developed in accordance
with internationally recognized principles on standardization
established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations
issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
