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 −20 and +150°C. 1.2 This test method is applicable only to relatively pure compounds. Values obtained for grossly impure compounds can be low because of the freezing out of one component during the determination. 1.3 In order that the test method may be used on many materials, a choice of certain alternatives and a selection of apparatus are permitted. The report (Section 12) requires that the selected alternatives must be stated. Materials to which the test method is applicable in particular detail include phenol, naphthalene, phthalic anhydride, and maleic anhydride. 1.4 The following applies to all specified limits in this test method: for purposes of determining conformance with this test method, an observed value or a calculated value shall be rounded off “to the nearest unit” in the right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29. NOTE 1—A companion test method is Test Method D 852. 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 specific hazard statements, see Section 8.
