Note 2—This test method is used in conjunction with Test Method Dwhich is used to measure breaking force and elongation of textile fabrics. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
ASTM D Sewn Seams of Woven Fabric
Combining values from the two systems may result in non-conformance with the standard. If a determination cannot be made as to which seam is the best suited for a particular fabric, all should be evaluated. By means of our testing expertise and modular product design, we will help find the solution that is right for you.
Link to Active This link will always route to the current Active version of the standard. Because sewn seam strength and sewn seam efficiency varies with each fabric, both of the standard seam assemblies, noted in Table 1should be used when comparing the seam strength of different fabrics.
Competent statistical assistance is recommended for the investigation of bias. The breaking force of the seam and fabric will permit estimation of seam efficiency. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. ASTM D measures the sewn seam strength in woven fabrics by applying a force perpendicular to the sewn seams.
As a minimum, the two parties should take a group of test specimens from the same lot of fabric to be evaluated, which utilize a like seam assembly or standard seam assembly. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing.
Link to Active This link will always route to the current Active version of the standard. Note 1—The grab test procedure in Test Method D shall be used to determine any characteristic in fabric that can affect the measurement of sewn seam strength. Table 1 lists the default seam assembly specifications to be used for fabrics made with fine, medium and heavy count yarns.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
These four seam engineering variables contribute to a textile product being able to achieve the maximum sewn seam strength performance and structural integrity when cut pieces of fabric are joined together. ASTM D is applicable to sewn seams obtained from a previously sewn article or seams sewn with fabric samples using either a specific seam assembly or production seam assemblies.

Lsc-2; Lsc-3; Lsc-4; and the maximum number of stitches per inch that can be used. Likewise, there are other textile structures, intended to be used multiple times, while also being subjected to various care and maintenance regimens. We are confident that we have what you are looking for. Asrm seams in woven fabrics can fail due to rupture, slippage, or any combination thereof.
Once deployed, it must be replaced; it cannot be re-used. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Historical Version s – view previous versions of standard. When the failure results in displacement of yarns, the textile product will need to be replaced. 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 d1863 two or more rows of stitching: Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing d6183 for tension, compression, bend, peel and much more.
If a bias is found, either its cause must be determined and corrected, or the purchaser and supplier must agree to interpret future test results in light of the known bias.
Rupture can be further categorized as failure or fabric, or sewing thread, or seam slippage.
