1. Scope | ||||||||||||||||||||||||||
1.1?This test method covers a general procedure for determining the solidification point of most organic chemicals having appreciable heats of fusion and solidification points between 4 ?C and 41 ?C. Note 1:?Other test methods for determining freeze point and
solidification point of aromatic hydrocarbons include Test Methods
D852, D1015, D1016, D3799, D4493, and D6269.
1.2?This test method is applicable to relatively pure compounds only. Solidification point depression is dependent on impurity concentrations. 1.3?The following applies to all specified limits in this test method: for purposes of determining conformance with applicable specifications using this test method, an observed value or a calculated value shall be rounded off to the nearest unit in the last right hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29. 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?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6?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. |
