Description:
The report describes the development and evaluation of a large chamber test method for measuring emissions from dry-process photocopiers. The test method was developed in two phases. Phase 1 was a single-laboratory evaluation at Research Triangle Institute (RTI) using four, mid-range, dry-process photocopiers. Phase 1 results indicate that the test method provides acceptable performance for characterizing emissions, adequately identifies differences in emissions between machines both in compounds emitted and their emission rates, and is capable of measuring both intra- and inter-machine variability in emissions. Toners appear to be the primary source of organic emissions from photocopiers. To investigate whether all chambers produce similar results, a four-laboratory, round-robin evaluation of the test method was performed in Phase 2. A single, dry-process photocopier was shipped in turn to each of four laboratories along with supplies (i.e., toner and paper). Phase 2 results demonstrate that the test method was used successfully in the different chambers to measure emissions and that differences in chamber design and construction appear to have minimal effect.
