If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias. The average bow or skew in a roll or lot or the range of bow or skew in a roll may be determined but are not normally used in the trade for acceptance or rejection.

Combining values from the two systems may result aztm non-conformance with the standard. As a minimum, the test samples to be used are as homogeneous as possible, are drawn from the material from which the disparate test results were obtained, and are randomly assigned in equal numbers to each laboratory for testing.

These defects may cause sewing problems in such fabrics and draping problems in finished products. These defects may cause sewing problems in such fabrics and draping problems in finished products.

Historical Version s – view previous versions of d382. Wavy or sharp breaks in the bow line are more detrimental to the appearance of small parts of a garment such as collars, pockets, and so forth than a gradual slope from a straight line. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. The average bow or skew in a roll or lot or the range of bow or skew in a roll may be determined but are not normally used in the trade for acceptance or rejection.

If there are differences of practical significance between reported test results for two laboratories or morecomparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance.

In some cases, a specified amount of skew is needed, for example, to prevent twisting of pant legs made of twill fabric. Matching plaids from distorted patterns may create serious problems for the garment manufacturer or home sewer.

Bow or skew can be induced during fabric manufacturing, dyeing, tentering, finishing, or other operations where a potential exists for uneven distribution of tensions across the fabric width. Link to Active This link will always route to the current Active version of the standard.
