1、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

2、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

3、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

5、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 pap

6、er 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 controlcarbo

7、n.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 imagequali

8、ty 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.

9、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 Dif

10、ferent 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 t

11、hat 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

12、 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 variati
