1、Designation:D558222Standard Test Method forDetermining Formaldehyde Levels from Wood ProductsUsing a Desiccator1This standard is issued under the fixed designation D5582;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of las
2、t revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers a small scale procedure formeasuring formaldehyde emission potential from wood prod-ucts under defined
3、 test conditions.The formaldehyde level isdetermined by collecting air-borne formaldehyde in a smalldistilled water reservoir within a closed desiccator.The quan-tity of formaldehyde is determined by a modification of theNational Institute for Occupational Safety and Health(NIOSH)3500 chromotropic a
4、cid test procedure.Other analytical pro-cedures may be used to determine formaldehyde emissionpotential provided that such methods give similar results to thechromotropic acid procedure.However,the test results and testreport must be properly qualified and the analytical procedureemployed must be no
5、ted.Procedures based on acetylacetoneand pararosaniline have been found to give similar results tochromotropic acid in other test methods used in determiningformaldehyde emission potential from wood products(see TestMethod E1333).1.2 Wood products typically evaluated by this test methodare made with
6、 urea-formaldehyde adhesives and includeparticle-board,hardwood plywood,and medium-density fiber-board.This test method is used for product quality control andis a small bench test method that correlates with the large-scaleacceptance test for determining formaldehyde levels fromwood products,Test M
7、ethod E1333.Alternative conditioningintervals may give better correlation,such as seven dayconditioning that parallels Test Method E1333.The generaldesiccator testing procedure may be modified for differentconditioning times to accommodate its use in manufacturingquality control.However,the test res
8、ults must be properlyqualified and the conditioning time employed must be noted.NOTE1If modifications are made to the conditioning period forquality control purposes,it is important that the modification is consis-tently applied.Otherwise,the results may not be comparable.1.3 The values stated in SI
9、 units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.1.4 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 stan
