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
9、end use fabrics may be inspected andgraded 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 fabri
10、c andfabric acceptance determination.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 o
11、f values reported by the purchaserand 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-tanc
12、e. As a minimum, ensure the test samples 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 usi

Apparatus6.1 A suitable fabric inspection machine providing a flatviewing area and an interruptible speed controlled fabricrewind. Examination and grading are
18、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.The overhead direct lighting source shall be mounted parallelto the viewing surface so as to
19、illuminate with direct perpen-dicular impinging light rays. The surface illumination levelshall be a minimum of 1075 lux (100 foot candles).6.2 The lighting source should be cool white preheat rapidstart fluorescent lamps with white reflectors and without bafflesor glues, or by agreement between the
20、 purchaser and supplier.7. 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 m or yd, select samplesas agreed upon by the purchaser and supplier. In the absence ofsuch a specification, a reliable statisti
21、cal sampling plan such asPractice D2903 or MIL-STD 105E may be used.8. Conditioning8.1 No conditioning is required.9. Defects and Tolerances9.1 The purchaser and the supplier 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
22、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 purchaser and the supplier mayagree upon the location, maximum size of a fabric character-istic and frequency of occurrence that
23、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 Defects not visible on the face of the fabric shall not becounted unless agreement to the contrary has been madebetween the purchaser
24、 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 acceptable level mutuallyagreed upon by the purchaser and supplier.9.6 The total shipment shall be rejected if the sampleinspect
25、ed exceeds the maximum acceptable defect level mutu-ally agreed upon by the purchaser and supplier.10. Procedure10.1 Pass the fabric longitudinally through the inspectionarea at a visual inspection speed, agreed upon between thepurchaser and supplier.10.2 Visually inspect and grade from a viewing di

Precision and Bias13.1 No justifiable statement can be made either on prec
42、i-sion or on the bias of Test Methods D5430 for visuallyinspecting and grading fabrics since the test results merelystates whether there is conformance to the criteria for successspecified in the procedure.13.2 BiasThe procedures of this test method produce atest value that can be defined only in te
43、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
