Summary of Practice4.1 This practice covers testing for physical properties ofcorrectable film ribbons, performance testing of correctablefilm ribbons under actual and simulated c

8、onditions on type-writers, and using the results to determine a comparative rating.All sample ribbons and supplies should be conditioned andtested under identical conditions in order to obtain comparativeresults.4.2 All sample ribbons may be tested and compared withknown control ribbons, a previous

9、set of data, or an establishedstandard.5. Significance and Use5.1 This practice should be used to evaluate performancequalities of correctable film ribbons on a comparative basisunder actual and simulated conditions.5.2 This practice is suitable for comparative service evalu-ation, research, and dev

10、elopment. It may also be used formanufacturing quality control.5.3 Users may choose any one test, a series of tests, or alltests, depending on their needs and interests in determining thedifferent characteristics of correctable film ribbons.6. General Considerations6.1 The following statements addre

11、ss some concerns aboutquality of the product. Although a complete list is not provided,the user must make the final determination of performancecriteria factors and level at which each factor impacts theparticular analysis.6.2 Visual InspectionInspect the ribbon for a smooth,uniform coating (on the

12、appropriate film base) free of folds,wrinkles, splices, blisters, uncoated areas, cracks, contamina-tion, and other detrimental defects that would make the ribbonunfit for its intended purpose. Examine for a smoothly slitstraight edge and proper winding without ragged and nickededges.1This practice
