Manufacturers of finished products that contain composite wood materials can have testing conducted on raw materials or even on finished products.

Care must be exercised in the astn of the results to formaldehyde concentrations in air and e11333 rates from products under different conditions of air change rate or loading ratio, or both.

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. When this test method is used for evaluating other than newly manufactured panel products after original application, installation or usethe method of packaging and shipping the product for testing shall be described in the test report.

This method employs a single set of environmental conditions but different product loading e13333 to assess formaldehyde concentrations in air and emission rates from certain wood products. As a result, agencies and programs, including the U. Conditions controlled in the procedure are as follows: Formaldehyde is widely used in pressed wood products such as particle board, plywood, fiberboard, glues, adhesives, which are found in flooring, furniture and other building materials.

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.

For specific hazard statements, see Section 7. Our familiarity with both national and international emissions testing standards, green building codes and rating systems enables UL to partner with manufacturers to conduct product emissions testing in ways that maximize efficiency and cost effectiveness.

This test method measures the formaldehyde concentration in air and emission rate from wood products containing formaldehyde by the use of e11333 large chamber under specific test conditions of temperature and xstm humidity, or conditions designed to simulate product use.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot. This abstract is a brief summary of the referenced 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.

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.

This test method is intended for use in conjunction with the test method referenced by HUD 24 for manufactured housing and by Minnesota Statutes wstm housing units and building materials. This test method provides a means of testing smaller samples and reduces the time required for testing. Measurement results are also used for comparing concentrations in air and emission rates from different wood products 2 and for determining compliance with product asgm.

Note 2-ASTM Committee D has developed Guide D which describes small-scale environmental equipment and techniques suitable for determining organic emissions and emission rates from materials and products used indoors.

Testing is conducted in environmental chambers operated at defined product loading, temperature and relative humidity.

This is a test method that specifies testing at various loading ratios for different product types.

The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot. 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.

A trusted resource for product emissions, UL has evaluated over 70, products for chemical emissions.

Still, product inhomogeneities must be considered when selecting and preparing samples for small-scale chamber testing. If another analytical procedure asstm used to determine the quantity of formaldehyde in the air sample, that procedure shall give results of equivalent or greater accuracy f1333 precision than the adapted chromotropic acid procedure.

However, the test results and test report must be properly qualified and must specify the make-up air flow, sample surface area, and chamber volume. DNPH is recognized as such a method. 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. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This test method provides a standard means of testing typical product sizes, such as 1. 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.
