Scope1.1 These test methods describe a procedure to establish anumerical designation for grading of fabrics from a visualinspection.1.2

3、 These test methods may be used for the delivery andacceptance of fabrics with requirements mutually agreed uponby the purchaser and the supplier.1.3 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 stan

Summary of Test Method4.1 Rolls or bolts of fabric are visually inspected andindividually graded at an examination station using an agreedupon point system.4.2 Fabric is normally inspected and graded on one sideonly. Certain types of end use fabrics may be inspected a

8、ndgraded on both sides as agreed upon between the purchaser andsupplier.5. Significance and Use5.1 Test Method D5430 is considered satisfactory for ac-ceptance testing a commercial shipments since the method hasbeen used extensively in the trade for grading of fabric andfabric acceptance determinati

9、on.5.2 The penalty points obtained in grading the same rolls orbolts of fabric may vary considerably when using each of thethree options listed herein. For this reason, the same pointassignment option should be used in cases of disagreementarising from differences of values reported by the purchaser

10、and the supplier.5.3 If there are differences of practical significance betweenreported test results for two laboratories (or more), compara-tive test should be performed to determine if there is astatistical bias between them, using competent statistical assis-tance. As a minimum, ensure the test s

11、amples to be used are ashomogeneous as possible, are drawn from the material fromwhich the disparate test results ere obtained, and are randomlyassigned in equal numbers to each laboratory for testing. Thetest results from the two laboratories should be compared usinga statistical test for unpaired

12、data, at a probability level chosenprior to the testing series. If a bias is found, either its causemust be found and corrected, or future test results for thatmaterial must be adjusted in consideration of the known bias.6. Apparatus6.1 A suitable fabric inspection machine providing a flatviewing ar

13、ea and an interruptible speed controlled fabricrewind. Examination and grading are usually done with over-head direct lighting. The inspection machine may be equippedwith the option of back lighting (transmitted) light providingthe choice by prior agreement depending on the fabric end use.1These tes
