Significance and Use
This test method provides a method of measurement of distillation range of volatile organic liquids. The relative volatility of organic liquids can be used with other tests for identification and measurement of quality. Therefore, this test method provides a test procedure for assessing compliance with a specification.
This test method also provides an empirical value of residue, solvent recovery capacity, and loss (or non-recovery) on heating. Organic liquids are used as solvents in many chemical processes. As the relative volatility, residual matter and recovery capability affect the efficiency of these processes, this test method is useful in manufacturing control.
1.1 This test method covers the determination of the distillation range of liquids boiling between 30 and 350°C, that are chemically stable during the distillation process, by manual or automatic distillation procedures.
1.2 This test method is applicable to organic liquids such as hydrocarbons, oxygenated compounds, chemical intermediates, and blends thereof.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) 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.
1.5 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
1.7 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. Specific hazard statements are given in Section 7.
