5.1 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. 1.1 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°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. For a specific hazard statement, see Section 8, Hazards. 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.

This document describes factors that may influence the composition of pure gases and homogeneous gas mixtures used for calibration purposes. This document only applies to gases or gas mixtures that are within the “utilization period”. It provides the following guidelines for the handling and use of calibration gas mixtures: — storage of calibration gas cylinders; — calibration gas withdrawal from cylinders; — transfer of calibration gas from cylinders to the point of calibration. It also outlines a method of assessing the stability of a gas mixture, taking into account the gas composition uncertainty given on the certificate and the user’s measurement uncertainty.
