ASTM D1217 – Standard Test Method for Density and Relative Density (Specific Gravity) of Liquids by Bingham Pycnometer
Description:
Significance and Use
5.1 Density is a fundamental physical property which can be used in conjunction with other properties to characterize pure hydrocarbons and their mixtures.
5.2 This test method was originally developed for the determination of the density of the ASTM Knock Test Reference Fuels n-heptane and isooctane, with an accuracy of 0.00003 g/mL. Although it is no longer employed extensively for this purpose, this test method is useful whenever accurate densities of pure hydrocarbons or petroleum fractions with boiling points between 90 °C and 110 °C are required.
Scope
1.1 This test method covers the measurement of the density of pure hydrocarbons or petroleum distillates boiling between 90 °C and 110 °C that can be handled in a normal fashion as a liquid at the specified test temperatures of 20 °C and 25 °C.
1.2 This test method provides a calculation procedure for the conversion of density to relative density (specific gravity).
1.3 WARNING—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use Caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
