1、Designation: D6828 02 (Reapproved 2015)Standard Test Method forStiffness of Fabric by Blade/Slot Procedure1This standard is issued under the fixed designation D6828; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of the stiff-ness of fabrics by measuring the force required to push aspecimen in
3、to a slot of predetermined width with a metal bladeworking at a predetermined capacity.NOTE 1For other methods for testing stiffness, refer to Test MethodsD1388, D4032, and D5732.1.2 This test method is applicable to fabrics of any fibercontent whose stiffness does not exceed the capacity of thePene
4、trator Beam apparatus. Specimens can be taken fromfabrics, rolls, or end products.1.3 The values stated in SI units are to be considered asstandard; the values inch-pound units are included for infor-mation only.1.4 This standard does not purport to address all of thesafety concerns, if any, associa
5、ted with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

8、terms used in this methodrefer to Terminology D4850. For other terms used in thismethod, refer to Terminology D123.4. Summary of Test Method4.1 A swatch of fabric rests on two flat plate supportsseparated by a fixed distance. A force is applied to the fabricswatch midway between the supports by mean
9、s of a bladeattached to a motor driven beam. The maximum force neededto push the fabric through the supports is measured as aresistance to bending of the fabric.5. Significance and Use5.1 This test method is considered satisfactory for qualitycontrol testing.5.2 If there are differences of practical
10、 significance betweenreported test results for two laboratories, comparative testsshould be performed to determine if there is a statistical biasbetween them, using competent statistical assistance. As aminimum, use test samples as homogeneous as possible, drawnfrom the material from which the dispa
11、rate test results wereobtained, and randomly assigned in equal number to eachlaboratory for testing. The test results from the two laboratoriesshould be compared using a statistical test for unpaired data, ata probability level chosen prior to the testing series. If a bias isfound, either its cause
12、must be found and corrected, or futureresults for the source material must be adjusted in consider-ation of the known bias.5.3 The stiffness of fabric relates to its resistance to bendingwith further processing and use. It measures the fiber and yarn1This test method is under the jurisdiction of AST

Sampling and Test Specimens7.1 Primary Sampling UnitConsider material as put-upfor shipment to be the primary sampling unit, such as rolls,bolts or pieces of fabric, or carton of garments or flat goods, asapplicable. (See Annex A1.)7.2 Laboratory Sampling UnitAs a laborat
19、ory samplingunit take from rolls at least one full-width piece of fabric thatis1m(1yd)inlength along the selvage (machine direction),after first removinga1m(1yd)length.7.3 Test SpecimensFrom each laboratory sampling unit,take five specimens 100 by 100 6 2.5 mm (4 by 4 6 0.1 in.).Take specimens repre
20、senting a broad distribution from differ-ent positions diagonally across the width of the laboratorysampling unit. Specimens should be staggered in such amanner that no specimens contain the same yarns. With theface of the specimen up, place a small locator mark in thelower right hand corner of the
21、specimen parallel to thewarp/machine direction (MD). (See Annex A2.) The mark willbe used to correctly position the specimen prior to testing sothat the stiffness of four different areas of the specimen can bedetermined. Label specimen to maintain identity.7.3.1 For fabric widths 100 mm (4 in.) or m
22、ore, take nospecimens closer than 25 mm (1 in) from the selvage edges ofthe laboratory sampling unit.7.3.2 For fabric widths less than 150 mm (4 in.), use theentire width of the laboratory sampling unit for specimens.7.3.3 Ensure specimens are free of folds, creases, orwrinkles.Avoid getting oil, wa
23、ter, grease, etc. on the specimenswhen handling.7.3.4 If the fabric has a pattern, ensure that the specimensare a representative sampling of the pattern.8.
