Title = Overview of Source/Sink Characterization Methods 
Abstract = Methods for characterizing indoor sources and sinks are continuously being developed and improved. Test protocols (e.g., for chamber tests) are needed to specify equipment requirements, testing conditions, and data analysis methods. Protocols are being published by standards-setting organizations (e.g., ASTM), international groups (e.g., CEC), and individual countries (e.g., Denmark). Both empirical models and fundamental mass transfer models are being developed to predict the emission behavior of sources and sinks. These models can be validated using dynamic chamber data from properly executed experiments. Validated source emissions models can be used to evaluate options for material selection or labelling based on chemical emission characteristics and known human responses to these chemicals. Another approach involves measurement of human sensory response and animal irritation response to identify sources with potential problems. Chamber systems that combine chemical emissions determinations with sensory response have also been developed. Use of emissions testing to evaluate and select indoor materials and products is expected to increase as test methods become standardized and assessment techniques are agreed upon.
