Description:
The article provides background information on indoor air emissions from office equipment, with emphasis on dry-process photocopy machines. The test method is described in detail along with results of a study to evaluate the test method using four dry-process photocopy machines. No standard test method exists to evaluate emissions from office equipment (e.g., ozone, volatile organic compounds, inorganic gases, and particulates), so it is difficult to compare data from different studies. As a result, the authors are developing a standardized guidance document for measuring indoor air emissions from office equipment and to develop lower emitting machines. Study results indicate that the test method provides acceptable performance for characterizing emissions, can adequately identify differences in emissions between machines both in compounds emitted and their emission rates, and can measure both intra- and inter-machine variability in emissions. Challenges and complications encountered in developing and implementing the test method include: heat generation, which can cause large increases in chamber temperature; Finite paper supplies for photocopy machines, which limit test duration; varying power requirements that may require changes in chamber electrical supply; and remote starting of the machines, which is necessary to maintain chamber integrity.
