Designation:D236910(Reapproved 2015)1Standard Test Method forVolatile Content of Coatings1This standard is issued under the fixed designation D2369;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1NOTEParagraph 9.3.2 was editorially corrected in June 2015.1.Scope1.1 This test method describes a procedure for the determi-nation of the weight percent volatile content of solventborneand waterborne coatings.Test specimens are heated at 110 65C for 60 min.NOTE1The coatings used in these round-robin studies representedair-dried,air-dried oxidizing,heat-cured baking systems,and also in-cluded multicomponent paint systems.1.2 Sixty minutes at 110 6 5C is a general purpose testmethod based on the precision obtained with both solventborneand waterborne coatings(see Section 9).1.3 This test method is viable for coatings wherein one ormore parts may,at ambient conditions,contain liquid coreac-tants that are volatile until a chemical reaction has occurredwith another component of the multi-package system.NOTE2Committee D01 has run round-robin studies on volatiles ofmulticomponent paint systems.The only change in procedure is to premixthe weighed components in the correct proportions and allow thespecimens to stand at room temperature for 1 h prior to placing them intothe oven.1.4 Test Method D5095 for Determination of the Nonvola-tile Content in Silanes,Siloxanes and Silane-Siloxane BlendsUsed in Masonry Water Repellent Treatments is the standardmethod for nonvolatile content of these types of materials.1.5 Test Methods D5403 for Volatile Content of RadiationCurable Materials is the standard method for determiningnonvolatile content of radiation curable coatings,inks andadhesives.1.6 Test Method D6419 for Volatile Content of Sheet-Fedand Coldset Web Offset Printing Inks is the method of choicefor these types of printing inks.1.7 This test method may not be applicable to all types ofcoatings.Other procedures may be substituted with mutualagreement between the producer and the user.NOTE3If unusual decomposition or degradation of the specimenoccurs during heating,the actual time and temperature used to cure thecoating in practice may be substituted for the time and temperaturespecified in this test method,subject to mutual agreement between theproducer and the user.The U.S.EPA Reference Method 24 specifies 1106 5C for 1 h for coatings.NOTE4Practice D3960 for Determining Volatile Organic Compound(VOC)Content of Paints and Related Coatings describes procedures andcalculations and provides guidance on selecting test methods to determineVOC content of solventborne and waterborne coatings.1.8 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.9 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D1193 Specification for Reagent WaterD3925 Practice for Sampling Liquid Paints and RelatedPigmented CoatingsD3960 Practice for Determining Volatile Organic Compound(VOC)Content of Paints and Related CoatingsD5095 Test Method for Determination of the NonvolatileContent in Silanes,Siloxanes and Silane-Siloxane BlendsUsed in Masonry Water Repellent TreatmentsD5403 Test Methods for Volatile Content of Radiation Cur-able MaterialsD6419 Test Method for Volatile Content of Sheet-Fed andColdset Web Offset Printing Inks1This test method is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.21 on Chemical Analysis of Paints and Paint Materials.Current edition approved June 1,2015.Published June 2015.Originallyapproved in 1965.Last previous edition approved in 2010 as D2369 101.DOI:10.1520/D2369-10R15E01.2For 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 States1 E145 Specification for Gravity-Convection and Forced-Ventilation OvensE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE180 Practice for Determining the Precision of ASTMMethods for Analysis and Testing of Industrial and Spe-cialty Chemicals(Withdrawn 2009)3E691 Practice for Conducting an Interlaboratory Study toDetermine the Preci
