To improve the reliability and accuracy of tests used to measure emissions of volatile organic compounds (VOCs) from samples of interior building products, the National Institute of Standards and Technology (NIST) and Virginia Tech (VT) have created a program to develop reference materials for volatile organic compounds emissions testing. A diffusion-controlled reference material and associated mechanistic model for predicting the emission profiles under various testing conditions have been developed. The feasibility of the reference material has been extensively evaluated and its capability in assessing emission testing performance has been demonstrated in a series of inter-laboratories studies. Reference materials have the potential to build consensus and confidence in emissions testing as well as to "level the playing field" for product testing laboratories and manufacturers.
