Summary of Test
ASTM D1683 is a test method used in seam engineering to determine the sewn seam strength in woven fabrics by applying a force perpendicular to the sewn seams until seam failure occurs. Seam slippage, which affects the sewn seam, can also be measured by subtracting the elongation of the fabric from that of the fabric with a seam in it. By comparing the properties of the fabric with and without seams, the optimum seam interaction can be determined using this test method.
A universal testing machine capable of performing a tensile test at a constant-rate-of-extension is required to run the test at a 305 ±10 mm/min (12.0 ± 0.5 in./min) grip separation rate. The standard recommends at least one grip to be mounted on the grip with a universal joint in order to allow the grip to rotate in the plane of the specimen. Before conducting ASTM D1683, it is important to read the entire specification in the relevant ASTM publication.
Recommended Equipment
Testing Procedure
- Prepare the specimen as described in the standard.
- Place the specimen between the grip jaws with the seam line centrally located between the clamp faces and perpendicular to the pulling force.
- The distance between grip jaws should be 75 ± 3 mm (3 ± 0.1in.). The force range should be set to allow break to occur between the 10 and 90 % of full-scale force.
- Apply tensile force until specimen rupture.
