11. Report 11.1 State that the specimens were tested as directed in TestMethod D3775. Describe the material or product sampled and the method of sampling used. 11.2 Report the following information: 11.2.1 Average number of ends and picks per cm (in.) calculated to the nearest individual yarn; when stating the count for the fabric, show the end count first followed by the pick count for each roll and for the lot. For example: Count=100 X 40 or 100 by 40 NOTE 4-The result is to be read as "one hundred by forty" not as 4000. 11.2.2 Thread count for each roll and for the lot, when requested, 11.2.3 Distance over which each count was taken, and the total yarns in each place counted, 11.2.4 Atmospheric conditions under which the tests were conducted and whether the specimens were conditioned as directed in Practice D1776.12. Precision and Bias 12.1 Summary-In comparing two averages of five observations when measuring the end or pick count of a woven fabric, the difference should not exceed about 0.42 ends or picks/in. in 95 out of 100 cases when all the observations were taken by the same well-trained operator using the same piece of equipment and specimens randomly drawn from the same sample of material. Larger differences are likely under all other circumstances. 12.2 Interlaboratory Test Data4-An interlaboratory test was run in 1981 in which randomly drawn specimens of four materials were tested in each of four laboratories. Two operators in each laboratory each tested two specimens of each material for both end count and pick count. The first fabric was a 65%polyester and 35%cotton seersucker type basket weave. The second fabric was a 65%polyester and 35% cotton gingham check. The third fabric was an 88%cotton and 12%polyester corduroy. The fourth fabric was a 100%cottondenim. The fabrics used in this interlaboratory study ranged in counts from 50 to 130 ends/in., and from 50 to 125 picks/in.The components of variance for end count and for pick count expressed as standard deviations were calculated to be as follows:Counts Single- OperatorComponent Within-LaboratoryComponent Between-LaboratoryComponentMaterial Compari-or Pick Counts0.3370.0000.458
