ASTM D7245-09(2014) PDF

Scope: 1.1 This test method is designed to measure total water which includes cure water resulting from the heat induced condensation reaction of coatings. Cure water cannot be measured directly by Test Method D4017. This task is accomplished by measuring water content in the vapors evolved during heating. This test method will yield total water content. This test method also permits for the simultaneous determination of total volatile content. The results of this test method may be used to calculate VOC content. Although this test method was designed for phenolic coatings, it can be used with other types of coatings. 1.2 Materials used for method development and evaluation had total water values from 20 to 37 %. Use of this test method on coatings outside these values will need to be validated by the user. 1.3 Sample heating is accomplished with a Brinkmann Instruments Model 832 drying oven,2 or other mutually agreed upon alternative, passing all of the evolved vapors into a Karl Fischer titration vessel. 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 to determine the applicability of regulatory limitations prior to use.
