ASTM D6897-16<\/h3>\n

Redline Standard: Standard Test Method for Vapor Pressure of Liquefied Petroleum Gases (LPG) (Expansion Method)<\/h4>\n
\n

ASTM D6897<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This test method covers the use of automatic vapor pressure instruments to determine the vapor pressure of liquefied petroleum gas products at a temperature of 37.8\u2009\u00b0C, vapor to liquid ratio of 0.5:1, and pressures from 200\u2009kPa to 1550\u2009kPa on a sample volume of 3.33\u2009mL.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> This test method is applicable to the determination of vapor pressures of liquefied petroleum gas products at temperatures from 37.8\u2009\u00b0C to 70\u2009\u00b0C, vapor to liquid ratios of 0.1:1 to 4:1, and pressures up to 3500\u2009kPa; however, the precision of the test method (see Section 15<\/span>) has only been determined for a vapor to liquid ratio of 0.5:1, at a temperature of 37.8\u2009\u00b0C, and a pressure range from 300\u2009kPa to 1500\u2009kPa.<\/p>\n

\n

Note 1:<\/span> This test method is not intended to determine the true vapor pressure of LPG samples, but rather determine and report the vapor pressure of LPG at the 37.8\u2009\u00b0C temperature and 0.5:1 vapor to liquid ratio as the Test Method D1267<\/span> method.<\/span><\/p>\n<\/p><\/div>\n

\n

Note 2:<\/span> This test method is not a true vapor pressure method and will not measure the full contribution from any dissolved gases such as nitrogen or helium if they are present. The contribution of light gases to the measured vapor pressure is highly dependent on the test temperature, type of gas, and V\/L ratio of the test.<\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n

1.3<\/span> The values stated in SI units are to be regarded as standard.<\/p>\n

\n

1.3.1<\/span> Exception\u2014<\/span>Non-SI units are included in parentheses for information only.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n

1.4<\/span> 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. For specific warning statements, see Appendix X2<\/span>.<\/span><\/i><\/p>\n<\/p><\/div>\n
