Abstract

The National Institute of Standards and Technology (NIST) and Virginia Tech (VT) are developing a volatile organic compound (VOC) reference material to validate product emissions chamber testing. To verify the storage method of the material and determine its potential shelf-life, a series of tests was completed to measure the film’s emission rates after storage times of up to 6 months. The emission rate of toluene was measured from each film in a 50 L stainless steel chamber after storage times of 1 day, 13 days, 23 days, 41 days, 62 days, 104 days, 139 days, and 181 days. Although an inverse relationship between material sample age and toluene emission rate was observed at 2 h and 24 h, the difference in the amount of toluene emitted from each of the different aged samples becomes less evident and eventually statistically indistinguishable at 48 h and beyond.
