This test method measures the sewn seam strength in woven fabrics by applying a force perpendicular to the sewn seams.
The grab test procedure in The test Method D5034 shall be 2 determine any characteristic in The fabric that can affect The measurement of sewn seam strength.
This test method is, informs the when a product force to rupture, a minimum elongation, or both are required to determine the sewn seam strength and seam slippage, or seam integrity of a particular fabric for a specified end use.
This test method can also be 2 determine either the sewn seam strength of textiles or the efficiency of a seam assembly with any given fabric. Additionally, the seam strengths of company's fabrics can be compared directly by using one of the standard seam assemblies specified in Table 1. Because the current information about laboratory precision is incomplete, comparative tests may be advisable.
