ASTM E1333-14

1.1 This test method measures the formaldehyde concentration in air and emission rate from wood products containing formaldehyde under conditions designed to simulate product use (see 11.5 and Note 9). The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity. The general procedures are also intended for testing product combinations at product-loading ratios and at air-exchange rates typical of the indoor environment (1).2 The products tested, the loading ratios and the air exchange rates employed are described in the test report.
