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 last 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 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 acid 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 noted.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 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 Method 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 results 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 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 standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.Forspecific hazard statements,see Section 6 and 8.2.5.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2E77 Test Method for Inspection and Verification of Ther-mometersE337 Test Method for Measuring Humidity with a Psy-chrometer(the Measurement of Wet-and Dry-Bulb Tem-peratures)E1333 Test Method for Determining Formaldehyde Concen-trations in Air and Emission Rates from Wood ProductsUsing a Large Chamber2.2 HUD Document:24 CFR 3280,Manufactured Home Construction and SafetyStandards,Federal Register,Vol 49,No.15532.3 NIOSH Document:Formaldehyde Method 3500,U.S.Department of Health,and Human Services32.4 Other Documents:Minnesota Statutes Section 144.495,325F.18,and 325F.181,Formaldehyde Gases in Building Materials4CaliforniaAir Resources Board(CARB),California Code ofRegulations Sections 93120-93120.12,Title 17 Airborne1This test method is under the jurisdiction of ASTM Committee D07 on Woodand is the direct responsibility of Subcommittee D07.03 on Panel Products.Current edition approved Aug.1,2022.Published September 2022.Originallyapproved in 1994.Last previous edition approved in 2014 as D5582 14.DOI:10.1520/D5582-22.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/www.dodssp.daps.mil.4Available from Print Communications,Dept.ofAdministration,117 UniversityAve.,St.Paul,MN 55155.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization establis
