Summary of Test Method4.1 This test method subjects a printed pattern to a con-trolled abrasive action similar to er

6、asing and provides acomparative measure of image removal.5. Significance and Use5.1 This test method is used to compare the relative eras-ability of similar ribbons having approximately the sameamount (degree) of ink (inking) transfer capability. It issuitable for compiling rankings for comparative

7、testing againsta control ribbon for service evaluation and quality control(research).6. Interferences6.1 The degree of image removal can and will vary due tothe differences and variations in paper, machines, inks, types ofink, and ribbon application.6.2 The use of (the) control ribbons is recommende

8、d (sinceit is impossible to match all possible causes of variation).7. Apparatus and Materials7.1 Typewriter, or other device for preparing a uniformprinted pattern. Special type for creating grid patterns isavailable from several typewriter manufacturers. Care must beexercised to assure the same ty

Refer to Practice F 497.7.2 Ribbon of known quality used as a control.7.3 Abrasion TesterThe Taber abraser Model 174, or itsequivalent shall be used.7.4 Abrasive WheelsThe grade of Calibrase wheels des-ignated as CS-10F shall be used.7.5 Auxiliary W

If it can not beidentified, use same s

Care should be takenthat an unused portion of the ribbon is tested.1This test method is under the jurisdiction of ASTM Committee F05 on Busi-ness Imaging Products and i

Calibration and Standardization9.1 Adjust the typewriter to produce a uniform patternsimilar in print darkness to typical printing. Maintain thisadjustment throughout th

15、e test series. See Practice F 497.9.2 Adjust the abrasion tester according to the instructionsfound in TAPPI Method T 476.10. Procedure10.1 Conduct the test in an environment with stable condi-tions of temperature and relative humidity. If available, stan-dard conditions 50.06 2.0 % relative humidit

16、y and 23.0 61.0C (73.4 6 3.6F) should be used.10.2 Create a uniform printed pattern approximately 0.6 by4.0 in. (15 by 102 mm) with each ribbon to be evaluated, andmount the patterns on the specimen mounting cards. Severalpatterns may be grouped together on one piece of paper andmounted on one card.

17、10.3 Subject each pattern to the abrasion test using thewheels with auxiliary 500-g weights. The duration of the testshould be the same for each pattern; 200 cycles has provedsatisfactory for fabric ribbons and bond paper.10.4 The number of cycles may be adjusted depending uponthe degree of abrasion

18、 required to make an effective evaluation.Once the number of cycles is established, all tests shall be runat that number.10.5 Run a sufficient number of replicate patterns from eachribbon to satisfy the precision requirements of the test. Forfabric ribbons printed on bond paper, a minimum of fiverep

19、licates is suggested.11. Results11.1 Visually examine and compare the abraded specimens.Establish a ranking order and compare to the control, that is“better than,” “equal to,” or “poorer than.”12. Report12.1 The report shall include the following:12.1.1 All test and instrument parameters (such as, t

20、ype ofpaper used number of abrasion cycles per test, temperature,relative humidity, etc.),12.2 Report a visual ranking order or comparison to thecontrol.13. Precision and Bias13.1 A repeatable ranking order can be established based onthe results of an evaluation performed by a single operator.Compar

21、ison of results with different operators may be effecteddue to judgment differences in evaluation of the images. Biasis unknown.14.
