1.1 This test method is for the determination of the weight percent of individual volatile organic compounds in low VOC content waterborne latex air-dry coatings. The method is intended primarily for analysis of waterborne coatings in which the material VOC content is below 5 weight percent. The method has been used successfully with higher VOC content waterborne coatings.
1.2 This method may also be used to measure the exempt volatile organic compound content (acetone, methyl acetate, and p-chlorobezotrifluoride) of waterborne coatings. The methodology is virtually identical to that used in Test Method D 6133 and similar to that used in Test Method D 6438
1.3 Volatile compounds that are present at the 0.05 weight percent level or greater can be determined. Solid phase microextraction will detect volatile compounds at lower levels.
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.
