The test report shall note the analytical procedure employed.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Conditions controlled in the procedure are as follows:.

DNPH is recognized as such a method. The values given in parentheses are asm conversions to inch-pound units that are provided for information only and are not considered standard. Manufacturers of finished products that contain composite wood materials can e13333 testing conducted on raw materials or even on finished products.

The conditions controlled in the procedure are the conditioning of atsm 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. The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity. The values given 1e333 parentheses are for information only.

This test method is intended for use in conjunction with the test aastm referenced by HUD 24 for manufactured housing and by Minnesota Statutes for housing units and building materials. A more sensitive analytical procedure is recommended for testing wood panel products where formaldehyde concentrations in air are e13333 to be at or below this level.

Testing is conducted in environmental chambers operated at defined product loading, temperature and relative humidity. 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 test method provides a standard means of testing typical product sizes, such as 1. Link to Active This link will always route to the current Active version of the standard. 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 A trusted resource for product emissions, UL has evaluated over 70, products for chemical emissions.

Variations in product 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 astk 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.

Link to Active This link will always route to the current Active version of the standard. This is a test method that specifies testing at various loading ratios for different product types. As a result, agencies and programs, including the U. Historical Version s – view previous versions of 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.

For specific hazard statements, see Section 7. 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 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. The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot.

However, the test results and test report must be properly qualified and the analytical procedure employed must be accurately described. 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.

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. 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. 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.

Note 1-The chromotropic acid analytical procedure described in this test method is applicable for testing urea-formaldehyde bonded wood products. This test method provides a means of testing smaller samples and reduces the time required for testing.

Historical Version s – view previous versions of standard. 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.

Any values given in parentheses are for information only. However, many manufacturers go beyond the record-keeping requirements and have their raw materials or finished products tested. 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.

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. DNPH is recognized as such a method.

However, the test results and test report must be properly qualified and must specify the make-up air flow, sample r1333 area, and chamber volume. The products tested, the loading ratios and the air exchange rates employed are described in the test report.

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.
