Significance and Use The effects of VOC sources on the indoor
air quality in buildings have not been well established. One
basic requirement that has emerged from indoor air quality
studies is the need for well-characterized test data on the
emission factors of VOCs from building materials. Standard test
method and procedure are a requirement for the comparison of
emission factor data from different products. This practice
describes a procedure for using a small environmental test
chamber to determine the emission factors of VOCs from wood-
based panels over a specified period of time. A pre-screening
analysis procedure is also provided to identify the VOCs emitted
from the products, to determine the appropriate GC/MS or GC/FID
analytical procedure, and to estimate required sampling volume
for the subsequent environmental chamber testing. Test results
obtained using this practice provide a basis for comparing the
VOC emission characteristics of different wood-based panel
products. The emission data can be used
