1、Designation: E 1333 96 (Reapproved 2002)Standard Test Method forDetermining Formaldehyde Concentrations in Air andEmission Rates from Wood Products Using a LargeChamber1This standard is issued under the fixed designation E 1333; the number immediately following the designation indicates the year ofo
2、riginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method measures the formaldehyde concentra-tion i
3、n air and emission rate from wood products containingformaldehyde under conditions designed to simulate productuse (see 11.5 and Note 7). The concentration in air andemission rate is determined in a large chamber under specifictest conditions of temperature and relative humidity. Thegeneral procedur
4、es are also intended for testing product com-binations at product-loading ratios and at air-exchange ratestypical of the indoor environment (1).2The products tested, theloading ratios and the air exchange rates employed are de-scribed in the test report.1.2 This test method determines the average fo
5、rmaldehydeconcentration in air and emission rate from a number of largesize samples. The average concentration and emission ratereported, thus, will not provide information on higher or loweremitting panels in the test lot.1.3 This method is primarily used for testing newly manu-factured panel produ
6、cts that are shipped for testing eitherseal-wrapped in polyethylene or with waster sheets, or withboth. When this test method is used for evaluating other thannewly manufactured panel products (after original application,installation or use), the method of packaging and shipping theproduct for testi
7、ng shall be described in the test report.1.4 The quantity of formaldehyde in the air sample takenfrom the chamber is determined by an adaptation of theNational Institute for Occupational Safety and Health (NIOSH)3500 chromotropic acid test procedure. If another analyticalprocedure is used to determi
8、ne the quantity of formaldehyde inthe air sample, that procedure shall give results of equivalent orgreater accuracy and precision than the adapted chromotropicacid procedure. Detailed procedures based on acetylacetone,pararosaniline (see Test Method D 5221), 2,4-dinitrophenylhydrazine (DNPH) (see T
9、est Method D 5197) and3-methyl-2-benzothiazoline (MBTH) (see Test MethodD 5014) have been found to give results equivalent or greaterin accuracy and precision than chromotropic acid. The testreport shall note the analytical procedure employed.NOTE 13The chromotropic acid analytical procedure describ
10、ed in thistest method is applicable for testing urea-formaldehyde bonded woodproducts. According to NIOSH (4th Edition, 8/15/94) the low end of theworking range for the chromotropic acid analytical procedure is 0.02 ppm.A more sensitive analytical procedure is recommended for testing woodpanel produ
11、cts where formaldehyde concentrations in air are anticipated tobe at or below this level. DNPH is recognized as such a method.1.5 This test method is used to determine compliance withrequirements such as those established for building materialsby the U.S. Department of Housing and Urban DevelopmentR
12、ules and Regulations 24 CFR 3280 for manufactured housingand by Minnesota Statutes Section 144.495. Measurementresults are also used for comparing concentrations in air andemission rates from different wood products (2) and fordetermining compliance with product standards.1.6 The values stated in SI
13、 units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.7 This test method is not designed for determining generalorganic emissions from all indoor materials and products.NOTE 2ASTM Committee D22 has developed Guide D 5116 whichdescribes small-scale enviro
14、nmental equipment and techniques suitablefor determining organic emissions and emission rates from materials andproducts used indoors.1.8 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to esta
