Significance and Use
5.1 Evaporation residue is an empirical measure of nonvolatile impurities in naphthalene. This test method is suitable for setting specifications and for use as an internal quality control tool.
1.1 This test method covers the determination of the evaporation residue of naphthalene.
1.2 This test method has been found applicable to determining residue in the range of 0.3 and 1.5 wt %.
1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice .
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 specific hazard statements, see Section . and
