|This practice measures the volatile organic compound (VOC)
content of solventborne and waterborne paints and related coatings
as determined from the quantity of material released from a sample
under specified bake conditions and subtracting exempt volatile
compounds and water if present.
NOTE 1-The regulatory definition, under the control of the U.S.
EPA, can change. To ensure currency, contact the local air
pollution control agency.
Certain organic compounds that may be released under the
specified bake conditions are not counted toward coating VOC
content because they do not participate appreciably in atmospheric
photochemical reactions. Such negligibly photochemically reactive
compounds are referred to, as exempt volatile compounds in this
NOTE 2-Information on the US EPAdefinition of VOC and a list of
the current US EPA approved exempt volatile compounds which have
been used in coatings, are provided in Appendix X3.
VOC content is calculated as a function of (1) the
volume of coating less water and exempt volatile compounds, and
(2) the volume of coating solids, and (3) the
weight of coating solids.
The values stated in SI units are to be regarded as
