ee1333 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.

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 concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity.

Formaldehyde is widely used in pressed wood products such as particle board, plywood, e133, glues, adhesives, which are found in flooring, furniture and other building materials. The general procedures are also intended for testing product combinations at product-loading ratios and at air-exchange rates typical of the indoor awtm 1.

This method employs a single set of environmental conditions but different product loading awtm to assess formaldehyde concentrations in air and emission rates from certain wood products.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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. 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.

ASTM does not give ast warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 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.

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

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

Care must be exercised in the extension ee1333 the results to formaldehyde concentrations in air and emission rates from products under different conditions of air change rate or loading ratio, or both.

Active view current version of standard. Conditions controlled in the procedure are as follows: Conditions controlled in the procedure are as follows:. Formaldehyde has been shown to present short- and long-term health risks.

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.

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

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.

DNPH is recognized as such a method. This is a test method that specifies testing at various loading ratios for different product types. Link to Active This link will always route to the current Active version of the standard. The products tested, the loading ratios and the air exchange rates employed are described in the test report. 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.

The concentration in air and emission rate is determined in a large chamber under specific test conditions of temperature and relative humidity. Note 1-The chromotropic acid analytical procedure described in this test method is applicable for testing urea-formaldehyde bonded wood products.

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 a result, agencies and programs, including the U. 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.

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. At the end of a specified time period in the test r1333, the air is sampled, and the concentration of formaldehyde in the air and emission rate are determined.

Manufacturers of finished products that contain composite wood materials can have testing conducted on raw materials e3133 even on finished products.
