Standard Test Method for Wale and Course Count of Weft Knitted Fabrics

Importancia y uso:

5.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them using competent statistical assistance. As a minimum, ensure that the test samples to be used are as homogeneous as possible and drawn from the material from which the disparate test results were obtained. The test specimens are to be randomly assigned in equal numbers to each laboratory for testing. The test results from the participating laboratories should be compared using a statistical test for unpaired data to a probability level chosen before initiation of the testing. If a bias is found, either its cause shall be found and corrected, or future test results for that material shall be adjusted in consideration of the known bias.

5.2 The results obtained by this test method may be used to determine if fabrics meet the tolerances for fabric counts given in Specification D3887.
