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.

Historical Version s – view previous versions of standard. For specific hazard statements, see Section 7. E333 results are also used for comparing concentrations in air and emission rates from different wood products 2 and for determining compliance with product standards. A trusted resource for product emissions, E133 has evaluated over 70, products for chemical emissions. The average concentration and emission rate reported, thus, will not provide information zstm higher or lower emitting panels in the test lot.

The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity. Building Materials Furniture and Bedding. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 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, e13333 conditions designed to simulate product use.

CARB Testing of Formaldehyde Emissions for Composite Wood Products

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.

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.

Variations in e13333 loading, temperature, relative humidity, and air exchange will affect formaldehyde emission rates and thus likely indoor air formaldehyde concentrations. The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot. 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.

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, zstm air circulation within the chamber.

Still, product inhomogeneities must be considered when selecting and preparing samples for small-scale chamber testing. As a result, agencies and programs, including the U. Historical Version s – view previous versions of standard. The test report shall note the analytical procedure employed.

Results obtained from this small-scale chamber test method are intended to be comparable to results obtained from testing larger product samples by the large chamber test method for wood products, ASTM Test Method E Link to Active This link will always route to the current Active version of the standard.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This abstract is a brief summary of the referenced standard.

This test method is intended for use in conjunction with the test method referenced by HUD 24 for manufactured housing and by Minnesota Statutes for housing units and building materials. The products tested, the loading ratios and the air exchange rates employed are described in the test report.

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.

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.

The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity. Manufacturers of finished products that contain composite wood materials can have testing conducted on raw materials or even on finished products. Formaldehyde has been shown to present short- and long-term health asrm.

Products that contain these materials are required to keep records indicating that they use only third-party certified boards in their finished products. 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. 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.

This test method provides a means of testing smaller samples and reduces the time required for testing. 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.

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.

Testing is conducted in environmental chambers operated at defined product loading, temperature and relative humidity. DNPH is recognized as such a method. However, many manufacturers go beyond the record-keeping requirements and have their raw materials or finished products tested.

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 atm testing shall be described in the test report.

This is a test qstm that specifies testing at various loading ratios for different product types. Note 1-The chromotropic acid analytical procedure described in this test method is applicable for testing urea-formaldehyde bonded wood products. 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.

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

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