1.1This test method measures the sewn seam strength in woven fabrics by applying a force perpendicular to the sewn seams.

1.1.1The axis perpendicular to the sewn seam can represent either the warp yarn axis or filling yarn axis, the same axis tested when using grab Test Method D5034.

1.1.1.1This test method is applicable to sewn seams obtained from a previously sewn article or seams sewn with fabric samples using one of two specific seam assemblies as shown in Table 1.

(A)A complete description of seam types and stitch types can be found in Practice D6193.

Note 1:When the performance of a woven textile structure requires data to indicate the maximum seam strength that will result in the failure of fabric on either side of seam, the standard seam can be changed to use the Lapped seam type construction with two or more rows of stitching: Lsc-2; Lsc-3; Lsc-4; and the maximum number of stitches per inch that can be used. (See Practice D6193.)
