In: Standard Practice Designation: D6670-01, American Society of Testing and Materials, Philadelphia, PA, July, 2001. 2001, 1-20. EPA/600/A-01/044. Zhang, J., Mason*, M., Nong, G., Zhu, J.J., Howard*, E.M., Shaw, C.Y., and Brown, S 11/30/2000 The Practice is intended for determining volatile organic compound (VOC) emissions from materials and products (building materials, material systems, furniture, consumer products, etc.) and equipment (printers, photocopiers, air cleaners, etc.) under environmental and product-usage conditions typical of those in office and residential buildings. It is for identifying VOCs emitted and determining their emission rates. It descibes the design, construction, peformance evaluation, and use of full-sclae chambers for VOC emission testing. While limited to measuring VOC emissions, many of its general principles and procedures (e.g., methods for evaluating the general performance of the chamber system) may also be useful for determining other chemical emissions (e.g., ozone, nitrogen dioxide),. Materials or products are placed in a full-scale test chemaber within which temperature, relative humidity, and air change are controlled. Air is sampled at the exhaust of or inside the chamber, and analyzed to identify the major emitted compounds and their concentrations. The measured concentrations are then used to determine the emission rates and/or the emission characteristics of the material or product. This information can be used to assess the contribution of the materials and products to the concentrations in the space of interest.
