Historical Version s - view previous versions of standard. More D 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.

CARB Testing of Formaldehyde Emissions for Composite Wood Products
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. The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot. When this test method is used for evaluating other than newly manufactured panel products after original application, installation or use , the method of packaging and shipping the product for testing shall be described in the test report.
