Care must be exercised in the asfm 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. 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.

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. The test report shall astk the analytical procedure employed.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory astn prior to use. The average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot. Testing is conducted in environmental chambers operated at defined product loading, temperature and relative humidity.

Results obtained from this small-scale chamber test method are intended to e1333 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.

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. For specific hazard statements, see Section 7. Historical Version s – view previous versions of standard. The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity.

However, many manufacturers go beyond the record-keeping requirements and have axtm raw materials or finished products tested.

DNPH is recognized as such a method. 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. Products that contain these materials are required to keep records indicating that they use only third-party certified boards in their finished products. Active view current version of standard. As a result, agencies and programs, including the U.

A trusted resource for product emissions, UL has evaluated over 70, products for chemical emissions. For specific hazard statements, see Section 7. 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 average concentration and emission rate reported, thus, will not provide information on higher or lower emitting panels in the test lot. 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. Still, product inhomogeneities must be considered when selecting and preparing samples for small-scale chamber testing. 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.

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. When this test method is w1333 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.

Any values given in parentheses are for information only.

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

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. 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.

This abstract is a brief summary of the referenced standard. Measurement results are also used s1333 comparing concentrations in air and emission rates from different wood products 2 and for determining compliance with product standards.

Conditions controlled in asm procedure are as follows: 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.

Historical Version s – view previous versions of standard. However, the test results and test report must be properly qualified and must specify the make-up air e1333, sample surface area, and chamber volume. 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 risks.
