7、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 andgraded on both sides as agreed

8、 upon between the purchaser andsupplier.5. Significance and Use5.1 Test Method D 5430 is considered satisfactory foracceptance testing a commercial shipments since the methodhas been used extensively in the trade for grading of fabric andfabric acceptance determination.5.2 The penalty points obtaine

9、d 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 purchaserand the supplier.5.3 If there are

10、 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 samples to be used are ashomogeneo

11、us 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 data, at a probability level chos

12、enprior 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.

Sampling7.1 With shipments which total 1000 m or yd or less, inspectand grade the total number of rolls or bolts.7.2 For shipments exceeding 1000

19、m or yd, select samplesas agreed upon by the purchaser and supplier. In the absence ofsuch a specification, a reliable statistical sampling plan such asPractice D 2903 or MIL-STD 105E may be used.8. Conditioning8.1 No conditioning is required.9. Defects and Tolerances9.1 The purchaser and the suppli

20、er shall agree on a list ofdefects to be used in grading fabric. See 2.1 and 2.2 and Refs.1-7 for publications of various lists of fabric defects which maybe used.9.1.1 The fabric defects listed shall be classified as either acritical defect, major defect, or minor defect.9.2 Where applicable, the p

21、urchaser and the supplier mayagree upon the location, maximum size of a fabric character-istic and frequency of occurrence that shall not be counted asa defect.9.3 The point count permissible frequency of any defecttype may be further qualified by agreement of the purchaserand the supplier.9.4 Defec

22、ts not visible on the face of the fabric shall not becounted unless agreement to the contrary has been madebetween the purchaser and the supplier.9.5 Each individual roll or bolt in 7.1 or 7.2 shall be rejectedif inspection and grading results in a total number of defectpoints exceeding the maximum

23、acceptable level mutuallyagreed upon by the purchaser and supplier.9.6 The total shipment shall be rejected if the sampleinspected exceeds the maximum acceptable defect level mutu-ally agreed upon by the purchaser and supplier.10. Procedure10.1 Pass the fabric longitudinally through the inspectionar

Precision and Bias13.1 No justifiable statement can be made either on preci-

41、sion or on the bias of Test Methods D 5430 for visuallyinspecting and grading fabrics since the test results merelystates whether there is conformance to the criteria for successspecified in the procedure.13.2 Bias The procedures of this test method produce atest value that can be defined only in te

42、rms of a test method.There is no indepedent, referee method by which bias may bedetermined. This test method has no known bias.REFERENCES(1) Apparel Quality Committee Report, “Guidelines for Purchasing bySpecifications,” 1978, Publication 660-43.(2) Technical Advisory Committee Report, “Piece Goods
