Designation:D258418Standard Test Method forIgnition Loss of Cured Reinforced Resins1This standard is issued under the fixed designation D2584;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.1.Scope1.1 This test method covers the determination of the ignitionloss of cured reinforced resins.This ignition loss shall beconsidered to be the resin content within the limitations of 4.2.1.2 The values stated in SI units are to be regarded as thestandard.1.3 This standard is used to measure and describe theresponse of composite material to heat under controlledconditions,but does not by itself incorporate all of the factorsrequired for fire hazard or fire assessments of the compositematerials under actual fire conditions.1.4 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.1.5 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.NOTE1There is no known ISO equivalent to this standard.1.6 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:2D618 Practice for Conditioning Plastics for TestingE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE2935 Practice for Conducting Equivalence Testing inLaboratory Applications3.Summary of Test Method3.1 The specimen contained in a crucible is ignited andallowed to burn until only ash and carbon remain.Thecarbonaceous residue is reduced to an ash by heating in amuffle furnace at 565C(1050F),cooled in a desiccator,andweighed.4.Significance and Use4.1 This test method is used to obtain the ignition loss of acured reinforced resin sample.NOTE2The basic concept of burning off of the organic matrix of areinforced polymer composite has also been shown to be a useful methodfor enabling a visual examination of the fiber architecture or laminatestructure of some reinforcements.4.2 If only glass fabric or filament is used as the reinforce-ment of an organic resin that is completely decomposed tovolatile materials under the conditions of this test and the smallamount of volatiles(water,residual solvent)that are potentiallypresent are ignored,the ignition loss shall be considered to bethe resin content of the sample.4.2.1 This test method does not provide a measure of resincontent for samples containing reinforcing materials that loseweight under the conditions of the test or containing resins orfillers that do not decompose to volatile materials released byignition.5.Apparatus5.1 Crucible,platinum or porcelain,approximately 30-mLcapacity.5.2 Electric Muffle Furnace,capable of maintaining a tem-perature of 565 6 28C(1050 6 50F).6.Test Specimen6.1 A minimum of three specimens shall be tested for eachsample.NOTE3It is often convenient to use samples obtained from specimensthat have been tested for mechanical properties such as flexural or tensile1This test method is under the jurisdiction of ASTM Committee D20 on Plasticsand is the direct responsibility of Subcommittee D20.18 on Reinforced Thermoset-ting Plastics.Current edition approved Sept.15,2018.Published October 2018.Originallyapproved in 1967.Last previous edition approved in 2011 as D2584-11.DOI:10.1520/D2584-18.2For 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.*A Summary of Changes section appears at the end of this standardCopyright 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 strength.Specimens obtained from these samples must be dry and thefractured areas removed,leaving square,unfrayed faces,before beingweighed and ignited.6.2 The specimen shall weigh approximately 5 g with amaximum size of 2.5 by 2.5 cm by thi
