ASTM | 2008 | 4 |
This test method may be used for process control during the manufacture of organic chemicals described in Section 1, for setting specifications, for development and research work, and to determine if contamination was introduced during shipment.
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 and 41 Ā° C.
Note 1āOther test methods for determining freeze point and solidification point of aromatic hydrocarbons include Test Methods D 852, D 1015, D 1016, D 3799, D 4493, and D 6269.
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 ā to the nearest unit ā in the last right hand digit used in expressing the specification limit, in accordance with the ā rounding-off method ā of Practice E 29.
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 and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Section 8, Hazards.
