EPA Method 204D:
VOLATILE ORGANIC COMPOUNDS EMISSIONS IN UNCAPTURED STREAM FROM TEMPORARY TOTAL ENCLOSURE

Summary:
A gas sample is extracted from the uncaptured exhaust duct of a TTE through a heated sample line and, if necessary, a glass fiber filter to a flame ionization analyzer (FIA).

Scope:
This procedure is applicable for determining the uncaptured volatile organic compounds (VOC) emissions from a temporary total enclosure (TTE). It is intended to be used as a segment in the development of liquid/gas or gas/gas protocols for determining VOC capture efficiency (CE) for surface coating and printing operations.
