Designation:F 597 83(Reapproved 2003)Standard Practice forEvaluation of One-Time Carbon Paper in Carbon-InterleavedBusiness Forms by Use of an Electric Typewriter1This standard is issued under the fixed designation F 597;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 practice covers a standardized procedure using anelectric typewriter to determine the image quality of one-timecarbon paper for use in carbon-interleaved business forms.1.2 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 Product2F 221 Terminology Relating to Carbon Paper and InkedRibbon Products and Images Made Therefrom2F 497 Practice for Use of the Electric and Electronic Type-writer as a Test Instrument23.Terminology Definitions3.1 Refer to Terminology F 221.4.Summary of Practice4.1 This practice consists of a comparison test under actualuse conditions whereby a sample of one-time carbon paper isinterleaved side by side with a control carbon of known imagequality into a business form(or with forms bond paper tosimulate a business form)and imaged on an electric typewriterat a designated setting and pressure.A visual comparison ismade of the typed images from both sample and controlcarbon.4.2 This practice is used primarily to determine whether ornot a one-time carbon will produce a satisfactory image in abusiness form of predetermined composition with a qualitysimilar to that of the control carbon.5.Significance and Use5.1 This practice is used primarily to evaluate the imagequality of a one-time carbon paper by comparison with acontrol carbon of known performance in a business form ofpredetermined composition on an electric typewriter.5.2 This practice can also be used for the selection of aone-time carbon for a particular business form where a controlcarbon does not exist.5.3 This practice can be used for production,quality control,and research and development.6.Interferences6.1 Different pressures and settings on the same typewritercan affect the carbon-image quality.6.2 Platens of different durometer in the same typewritercan affect the carbon-image quality.6.3 Different typewriters can affect the carbon-image qual-ity.6.4 The length of time,the pressure,and the temperatureduring which the carbons are interleaved in the form can affectthe carbon-image quality.6.5 The length of time that the carbon paper was originallycoated and the storage conditions during that period can affectthe image quality.6.6 Weight,thickness,and finish of form bond paper canaffect image quality.6.7 Basis Weight of carbon substrate and carbon ink hard-ness,coat weight or thickness,can affect image quality.6.8 Typewriter platen misalignment could produce lighterimages on the left of the form than on the right or reverse.6.8.1 To check the platen make write with control carbons,remove carbons,cut vertically,replace in form in the sameorder,but reverse the left and right positions of each carbonsheet.Repeat exactly the same write and examine carbon copyfor evidence of variation.7.Apparatus7.1 Commercial Electric Typewriter,see Practice F 497.1This practice is under the jurisdiction of ASTM Committee F05 on BusinessImaging Products,and is the direct responsibility of Subcommittee F05.02 onInked-Transfer Imaging Products.Current edition approved Oct.28,1983.Published December 1983.Originallypublished as F 597 78.Last previous edition F 597 78.2Annual Book of ASTM Standards,Vol 15.09.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.8.Material8.1 Carbon-Interleaved Business Forms.8.2 One-Time Carbon,for control.8.3 Forms Bond Paper.9.Sampling9.1 Sample the roll carbon or carbon sheets in accordancewith Practice D 585.10.Test Specimen and Sample Preparation10.1 Comparison with Carbon-Interleaved in a FormCutthe test specimens to the same length and half the width of thecarbon interleaved in the form,and in the same machine andcross-direction dimensions as the interleaved carbon.Thenumber of specimens will be one less than the number of partsin the form.10.2 Comparison with Control Carbon in a Form of Speci-fied Dimensions,Without Interleaved CarbonCut the sampleand control specimens to half the width and the same length asthe form,the length being in the machine direction of thecarbon paper.The number of specimens will be one less thanthe number of parts specified for the form.10.3 Form Dimens
