This test method measures the formaldehyde concentration in air and emission rate from wood products containing formaldehyde by the use of a large chamber under specific test conditions of temperature and relative humidity, or conditions designed to simulate product use. This method employs a single set of environmental conditions but different product loading ratios to assess formaldehyde concentrations in air and emission rates from certain wood products. The conditions controlled in the procedure are the conditioning of specimens prior to testing, exposed surface area of the specimens in the test chamber, test chamber temperature and relative humidity, number of air changes per hour, and air circulation within the chamber. At the end of a specified time period in the test chamber, the air is sampled, and the concentration of formaldehyde in the air and emission rate are determined.
