Standard Test Method for Determination of the Weight Percent Individual Volatile Organic Compounds in Waterborne Air-Dry Coatings by Gas Chromatography

Scope

This test method is for the determination of the weight percent of individual volatile organic compounds in waterborne air-dry coatings. This method can be used to determine the weight percent organic content of waterborne coatings in which the volatile organic compound weight percent is below 5 percent. The method has been used successfully with higher content waterborne coatings and with solventborne coatings. This method may also be used to measure the exempt volatile organic compound content (for example, acetone, methyl acetate, t-butyl acetate and p-chlorobezotrifluoride) of waterborne and solvent-borne coatings. The methodology is virtually identical to that used in Test Method D6133 which, as written, is specific for only exempt volatile compounds. Volatile compounds that are present at the 0.005 weight percent level (50 ppm) or greater can be determined. Volatile organic compound content of a coating can be calculated using data from Test Method D6886 but requires other data (see Appendix X2.).
