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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. This test method provides a standard means of testing typical product sizes, such as 1.

This test 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. Conditions controlled in the procedure are as follows:. 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.

If another analytical procedure is used to determine the quantity of formaldehyde in the air sample, that procedure shall give results of equivalent or greater accuracy and precision than the adapted chromotropic acid procedure. The test report shall note the analytical procedure employed. A more sensitive analytical procedure is recommended for testing wood panel products where formaldehyde concentrations in air are anticipated to be at or below this level.

DNPH is recognized as such a method. Measurement results are also used for comparing concentrations in air and emission rates from different wood products 2 and for determining compliance with product standards. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
