Designation:D158298(Reapproved 2017)Standard Test Method forNonvolatile Content of Liquid Phenol,Resorcinol,andMelamine Adhesives1This standard is issued under the fixed designation D1582;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 the determination of nonvolatilecontent or total solids of liquid phenol,resorcinol,andmelamine adhesives with or without hardener(Note 1)addedand containing high-boiling and low-boiling volatile organicsolvents or water,or both.NOTE1Some low molecular weight materials in the adhesive may belost if hardener is not used.When a hardener is used,it must be mixed inaccordance with the manufacturers instructions.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 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.For specific precautions,see 5.2.1.4 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:2D907 Terminology of Adhesives3.Terminology3.1 DefinitionsMany of the terms in this test method aredefined in Terminology D907.4.Summary of Test Method4.1 Without HardenerA weighed amount of adhesive andquartz sand are oven-dried,cooled in a desiccator,andweighed.The percent nonvolatile content is calculated basedon the amount remaining.4.2 With HardenerA weighed amount of mixed adhesiveis oven dried,cooled in a desiccator,and weighed.The percentnonvolatile content is calculated based on the amount remain-ing.5.Apparatus5.1 Petri Dish,00 by 22 mm or its equivalent.5.2 Circulating-Air Oven,capable of maintaining tempera-tures of 70 6 1C,105 6 1C,and 150 6 1C.(Warning Asafety(explosion-proof)oven should be used when volatilematerials are likely to burn or explode.)5.3 Desiccator,with drying agent and tray.5.4 Analytical Balance,accurate to 1 mg.6.Sampling6.1 Except in special cases,take a composite sample fromthree or more separate containers chosen at random.Also,takesamples from containers which appear to be nonrepresentativeand test such samples separately.Place the samples immedi-ately in airtight containers,filled to prevent excessive air spaceabove the adhesive,and take precautions to reduce evaporationor drying to a minimum.Mix the adhesive in the containerthoroughly if there is a tendency for the materials to separate.6.2 Test three specimens of each sample.7.Procedure7.1 70C Drying Temperature Without Hardener:7.1.1 Place approximately 20 g of the adhesive in a coveredweighing bottle.7.1.2 Place approximately 10 g of fine,oven-dried quartzsand in an open Petri dish,together with a small glass stirringrod,and weigh the dish,rod,and contents to the nearest 1 mgon the analytical balance.Weigh out to the nearest 1 mgapproximately 2 g of the adhesive by difference from theweighing bottle,keeping the bottle covered as much as1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.30 on WoodAdhesives.Current edition approved Aug.1,2017.Published August 2017.Originallyapproved in 1958.Last previous edition approved in 2011 as D1582 98(2011).DOI:10.1520/D1582-98R17.2For 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.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 established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 possible.Mix the adhesive and quartz sand intimately bymeans of the stirring rod and distribute uniformly over thebottom of the dish in as thin a layer as possible.Condition thespecimen at 23 6 1C for at least 16 h.7.1.3 Place the dish with the rod and contents in the oven at70 6 1C until a constant weight is reached.7.1.4 Place the warm dish immediately in the desiccator andallow to cool to room temperature before weighing
