Designation:D 777 97(Reapproved 2002)An American National StandardStandard Test Methods forFlammability of Treated Paper and Paperboard1This standard is issued under the fixed designation D 777;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This is a fire-test-response standard.1.2 These test methods cover the determination of flamma-bility of paper and paperboards of all types no more than116in.(1.6 mm)in thickness,that have been treated to retard thespread of flame when ignited.Such papers are commonlydesignated as flame-retardant-treated.1.3 These test methods may be used with,and may be usedto distinguish between,paper and paperboard materials havinga flame-retardant-treatment removed by leaching in water,andthose whose flame-retardant-treatment is not removed by waterleaching.1.4 These test methods appear as follows:SectionTest Method AFlammability of Treated Paper and Paperboard Af-ter Leaching for 4 h With 24C Reagent Water8.1Test Method BFlammability of Treated Paper and PaperboardWithout Leaching8.21.5 The primary intended use of Test Method A is withpaper or paperboard materials having a flame-retardant treat-ment that is not removed by water leaching,or to specify theproperties of such materials.1.6 The primary intended use of Test Method B is withpaper or paperboard materials having a flame-retardant treat-ment known to be removed under the leaching conditionsspecified in Test Method A,or where non-removal of theflame-retardant treatment by water leaching is not a desired orspecified property.1.7 This standard should be used to measure and describethe properties of materials,products,or assemblies in responseto heat and flame under controlled laboratory conditions andshould not be used to describe or appraise the fire hazard orfire risk of materials,products,or assemblies under actual fireconditions.However,results of this test may be used aselements of a fire risk assessment which takes into account allof the factors which are pertinent to an assessment of the firehazard of a particular end use.1.8 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:D 585 Practice for Sampling and Accepting a Single Lot ofPaper,Paperboard,Fiberboard,and Related Product2D 685 Practice for Conditioning Paper and Paper Productsfor Testing2D 1193 Specification for Reagent Water3D 1968 Terminology Relating to Paper and Paper Products2E 122 Practice for Calculating Sample Size to Estimate,with a Specified Tolerable Error,the Average for a Char-acteristic of a Lot or Process4E 176 Terminology of Fire Standards53.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 char length,nthe length of charred material inmillimetres(or inches)removed from the specimen under theconditions of these test methods.3.1.2 flaming time,nthe time in seconds a specimencontinues to burn under the conditions of these test methodsafter removal of the burner flame.3.1.3 glowing time,nthe time in seconds a specimencontinues to glow under the conditions of these test methodsafter it has ceased to flame.3.1.4 Type I flame retarded,apaper or paperboard havingflame-retardant treatment removed by leaching with waterunder the conditions described in these test methods.3.1.5 Type II flame retarded,apaper or paperboard havingflame-retardant treatment not removed by leaching with waterunder the conditions described in these test methods.3.2 For terms associated with fire issues use TerminologyE 176.1These test methods are under the jurisdiction of ASTM Committee D06 onPaper and Paper Products and are the direct responsibility of Subcommittee D06.92on Test Methods.Current edition approved May 10,1997.Published February 1998.Originallypublished as D 777 44T.Last previous edition D 777 93.Discontinued 1981 andreinstated 1993.2Annual Book of ASTM Standards,Vol 15.09.3Annual Book of ASTM Standards,Vol 11.01.4Annual Book of ASTM Standards,Vol 14.02.5Annual Book of ASTM Standards,Vol 04.07.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.3.3 For terms associated with paper issues use TerminologyD 1968.4.Significance and Use4.1 The utility of paper and paperboard for many functionaland decorative purposes requires resistance to the spread offlame.These test methods are useful in both qualitative andquantitative measurement of the flame retardant property ofpaper and paperboard.Certain uses may also require a knowl-edge of the durability of the flame-retardant treatments a
