Note 1-The chromotropic acid analytical procedure described in this test method is applicable for asym urea-formaldehyde bonded wood products. Variations in product loading, temperature, relative humidity, and air exchange will affect formaldehyde emission rates and thus likely indoor air formaldehyde concentrations.

Formaldehyde is widely used in pressed wood products such as particle board, plywood, fiberboard, glues, adhesives, which are found in flooring, ast, and other building materials. Active view current version of standard. Historical Version s – view previous versions of standard. As a result, agencies and programs, including the U.

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 asym 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 asstm for testing shall be described in the test report.

Any values given in parentheses are for information only. The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity. 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.

Still, product inhomogeneities must be considered when selecting and preparing samples for small-scale chamber testing.

Measurement results are also used e133 comparing concentrations in air and emission rates from different wood products 2 and for determining compliance with product standards. For specific hazard statements, see Section 7. A trusted resource for product emissions, UL has evaluated over 70, products for chemical emissions.

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

DNPH is recognized as such a method. 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.

As with ASTM Test Method Eother analytical procedures may be used to determine the quantity of formaldehyde in the air sample provided that such methods give results comparable to those obtained by using the chromotropic acid procedure. The values given in parentheses are for information only.

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.

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. DNPH is recognized as such a method. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

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.

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. Conditions controlled in the e333 are as follows:. However, the test results and test report must be awtm qualified and must specify the make-up air flow, sample surface area, and chamber volume.

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. For specific hazard statements, see Section 7.

Formaldehyde has been aetm to present short- and long-term health risks. 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.

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 means of testing smaller samples and reduces the time required for testing. Link to Active This link will always route to the current Active version of the standard. Testing is conducted in environmental chambers operated at defined product loading, temperature and relative humidity.

The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity. The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot. The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot.

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 This is a test method that specifies testing at various loading ratios for different product types. However, many manufacturers go beyond the record-keeping requirements and have their raw materials or finished products tested.
