United States15.2 The penalty points obtained in grading the same rolls or bolts of fabric may vary considerably when using each of the threeoptions listed herein. For this reason, the same point assignment option should be used

14、in cases of disagreement arising fromdifferences of values reported by the purchaser and the supplier.5.3 If there are differences of practical significance between reported test results for two laboratories (or more), comparative testshould be performed to determine if there is a statistical bias b

15、etween them, using competent statistical assistance. As a minimum,ensure the test samples to be used are as homogeneous as possible, are drawn from the material from which the disparate test resultsere obtained, and are randomly assigned in equal numbers to each laboratory for testing. The test resu

16、lts from the two laboratoriesshould be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias isfound, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of thekno

17、wn bias.6. Apparatus6.1 A suitable fabric inspection machine providing a flat viewing area and an interruptible speed controlled fabric rewind.Examination and grading are usually done with overhead direct lighting. The inspection machine may be equipped with the optionof back lighting (transmitted)

18、light providing the choice by prior agreement depending on the fabric end use. The overhead directlighting source shall be mounted parallel to the viewing surface so as to illuminate with direct perpendicular impinging light rays.The surface illumination level shall be a minimum of 1075 lux (100 foo

19、t candles).6.2 The lighting source should be cool white preheat rapid start fluorescent lamps having a correlated color temperature of 4100to 4500 K with white reflectors and without baffles or glues, or by agreement between the purchaser and supplier.7. Sampling7.1 With shipments which total 1000 m

20、 or yd or less, inspect and grade the total number of rolls or bolts.7.2 For shipments exceeding 1000 m or yd, select samples as agreed upon by the purchaser and supplier. In the absence of sucha specification, a reliable statistical sampling plan such as Practice D2903 or MIL-STD 105E may be used.8

21、. Conditioning8.1 No conditioning is required.9. Defects and Tolerances9.1 The purchaser and the supplier shall agree on a list of defects to be used in grading fabric. See 2.1 and 2.2 and Refs. 1-7for publications of various lists of fabric defects which may be used.9.1.1 The fabric defects listed

22、shall be classified as either a critical defect, major defect, or minor defect.9.2 Where applicable, the purchaser and the supplier may agree upon the location, maximum size of a fabric characteristic andfrequency of occurrence that shall not be counted as a defect.9.3 The point count permissible fr

23、equency of any defect type may be further qualified by agreement of the purchaser and thesupplier.9.4 Defects not visible on the face of the fabric shall not be counted unless agreement to the contrary has been made betweenthe purchaser and the supplier.9.5 Each individual roll or bolt in 7.1 or 7.2

24、 shall be rejected if inspection and grading results in a total number of defect pointsexceeding the maximum acceptable level mutually agreed upon by the purchaser and supplier.9.6 The total shipment shall be rejected if the sample inspected exceeds the maximum acceptable defect level mutually agree

Procedure10.1 Pass the fabric longitudinally through the inspection area at a visual inspection speed, agreed upon between the purchaserand supplier.10.2 Visually inspect and grade from a viewing distance of one metre or yard while the fabric is in motion. Fab

26、ric may bestopped to grade when necessary to affirm marginal defects and defects may be flagged.10.3 Inspect and grade the total length of each roll or bolt sampled.10.4 Detect and assign points to defects observed as agreed upon in 9.1-9.4 using options A (10.6), B (10.7), or C (10.8).10.5 Assign p
