Designation:F 509 86(Reapproved 2000)e1Standard Practice for TestingOne-Time Carbonizing Tissue for Pinholes1This standard is issued under the fixed designation F 509;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.e1NOTEKeywords were added in February 2000.1.Scope1.1 This practice covers the determination of the existenceof pinholes in one-time carbonizing tissues.1.2 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of whoever uses this standard to consult andestablish appropriate safety and health practices and deter-mine the applicability 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 Products2F 221 Terminology Relating to Carbon Paper and InkedRibbon Products and Images Made Therefrom23.Terminology3.1 DefinitionsFor other definitions relating to carbonpaper and inked ribbon products,see Terminology F 221.3.2 Definitions of Terms Specific to This Standard:3.2.1 carbonizing bonda white opaque paper that is usedfor one-time carbon ink coatings.3.2.2control one-time carbon tissuea tissue that is ofknown quality and performance for one-time carbon inkcoatings.3.2.3 one-time carbonizing tissuea tissue that is used forone-time carbon ink coatings.3.2.4 pinholean opening in the carbon tissue that permitsthe coating to penetrate through to the uncoated side.4.Summary of Practice4.1 Across-the-web samples are taken from the outsidewraps of a roll of tissue and 4.25 by 11.00-in.(107.9 by279.4-mm)test specimens are cut from these samples so thattheir length is parallel to the cross direction.The specimens areidentified and checked for ink penetration using special testink,a draw-down rod instrument and special receptor paper onwhich a lined rectangular pattern is drawn.The same check isrepeated with an acceptable control tissue and the test resultsfrom the specimens and the control are compared visually,using the rectangular area.5.Significance and Use5.1 This practice is to be used to provide a visual means ofdetermining the existence of pinholes by penetration of a dyesolution through the pinhole into a white receptor paper.5.2 The practice is suitable for manufacturing control andwill give close correlation with the end product.5.3 This practice is suitable for comparative service evalu-ation and development.5.4 The initial appearance will change with time due tocontinued migration of dye solution into the receptor paper andthe size of the colored areas will not represent the actual sizeof the pinholes through which the solution was exuded.6.Apparatus6.1 Weight,2-lb(907-g).6.2 Draw-Down Rod Instrument(see Fig.1).6.3 Paper Cutter,18 by 18-in.(457.2 by 457.2-mm),thathas an attachment for ensuring parallelism of opposite edges.7.Reagents and Materials7.1 Test InkThe test ink is a solution of 33%methylvioletbase“B”in Oleic Acid.37.2 PadA minimum of ten sheets of white forms bondpaper.7.3 Control Carbon Tissue(3.2),4.25 by 11.00-in.(107.9by 279.4-mm)sheets,of the same type,grade,and basis weightas the test specimens.7.4 Special Receptor Paper4(3.1),8.5 by 11.0-in.(215.9 by279.4-mm),12 lb(17 x 22 500 or 45.1 g/m2)white,coated,pigmented carbonizing bond for receiving dye solution trans-ferred through tissue.Arectangular-lined area 2.5 by 8 in.(63.5by 203.2 mm)is ruled in the center of the sheet.7.5 Tissue Specimens(See 7.3),4.25 by 11-in.(107.9 by279.4-mm).1This practice is under the jurisdiction of ASTM Committee F-5 on BusinessCopy Products and is the direct responsibility of Subcommittee F05.02 on CarbonPaper and Inked Ribbons.Current edition approved April 25,1986.Published June 1986.Originallypublished as F 509 77.Last previous edition F 509 77(1982).2Annual Book of ASTM Standards,Vol 15.09.3Methylviolet Oleate,DS No.1289,may be obtained from Dye Spec.Inc;ormake from Methylviolet Base“B”and oleic acid.4Adrol,12 lb(17 x 22 500 or 45.1 g/m2),available from Kimberly Clark,orsimilar quality 12 lb(17 x 22 500 or 45.1 g/m2)carbonizing bond paper has beenfound satisfactory for this purpose.1Copyright ASTM,100 Barr Harbor Drive,West Conshohocken,PA 19428-2959,United States.NOTE1The overall weight of the instrument should be 4.00 6 0.25 lb(1.81 6 0.11 kg),and the hook bolt should be long enough to adjust the handlelevel with the surface.1)Sheet Metal PlateBrass,3.0 by 6.5 by 3.2 in.(76.2 by 165.1 by 3.2 mm)2)Weight3-lb(1.36-kg)steel block,2.75 by 4.00 by 0.88 in.(69.9 by 101.6 by 22.2 mm),drilled and tapped to accommodate socket-head and round-head ma-chine screws.3)Right-Angle Bracket,3.0 by 0.5 in.(76.2 by 6.4 mm)wide.4)Round-Heat Machine Screws,25)Round-Head Wood Screws,4.6)Wood
