Standard Test Method for Freezing Points of High-Purity Hydrocarbons (Withdrawn 2019)
SIGNIFICANCE AND USE
4.1 The freezing point measured by this test method, when used in conjunction with the physical constants for the hydrocarbons listed in Test Method D1016, allows the determination of the purity of the material under test. A knowledge of the purity of these hydrocarbons is often needed to help control their manufacture and to determine their suitability for use as reagent chemicals or for conversion to other chemical intermediates or finished products.
SCOPE
1.1 This test method covers a procedure for the precise measurement of the freezing points of high-purity hydrocarbons.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.3 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 hazard statements, see 5.1, 6.1 and 6.2.
Note 1: For the calculation of the molal purity of essentially pure compounds from measured freezing points and for procedures to be used for the sampling and determination of purity of certain specific compounds, see Test Method D1016.
WITHDRAWN RATIONALE
This test method covers a procedure for the precise measurement of the freezing points of high-purity hydrocarbons.
Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in December 2019 for the following reasons: (1) D1015 was developed, along with D1016, in the 1940s for the purpose of determination of purity of hydrocarbons using freezing point measurements. This method of testing hydrocarbon purity has been replaced by more precise instrument techniques such as gas chromatography in the industry. (2) The precision statements (repeatability and reproducibility) do not conform to current ASTM requirements and the precision of the method was not obtained in accordance with RR: D02-1007 or ASTM D6300. This standard, together with its companion method D1015, are being withdrawn with no replacement because it is no longer relevant as it is not used by the industry.
