The test specimens should then be randomly assigned in equal numbers to each laboratory for testing.
ASTM D/DM – 17() – Standard Test Method for Failure in Sewn Seams of Woven Fabrics
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.
Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice zstm static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
Referenced Documents purchase separately The documents listed below are referenced within the subject sstm but are not provided as part of the standard.
Link to Active This link will always route to the current Active version of the standard. Rupture can be further categorized as failure or fabric, or sewing thread, or seam slippage. We are confident that we have what you are looking for. Once deployed, it must be replaced; it cannot be re-used.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Combining values from the two systems asstm result in non-conformance with the standard. 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.
This test method can be used as an aid for estimating seam strength for any given fabric. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Historical Version s – dd1683 previous versions of standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Competent statistical assistance is recommended for the investigation of bias.
By means of our testing expertise and modular product design, we will help find the solution that is right for you. Forces wstm to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.
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 with two or more rows of stitching: Give our test engineers a call today for help configuring the best test machine and accessories according asmt your standard.
Note 2—This test method is used in conjunction with Test Method Dwhich is used to measure breaking force and elongation of textile fabrics. ASTM D measures the sewn seam strength in woven fabrics by applying a force perpendicular to the sewn seams.

Lsc-2; Lsc-3; Lsc-4; and the maximum number of stitches per inch that can be used. Combining values from the two systems may result in non-conformance with the standard. Active view current version of 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.
Likewise, there are other textile structures, intended to be used multiple times, while also being subjected to various care and maintenance regimens.
Table 1 lists the default seam assembly specifications to be used astk fabrics made with fine, medium and heavy count yarns. The breaking force of the seam and fabric will permit estimation of seam efficiency.
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. If a determination cannot be made as to which seam is the best atm for a particular fabric, all should be evaluated.
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. 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.
Sewn seams in woven fabrics can fail due to rupture, slippage, or any combination thereof. Satm to Active This link will always route to the current Active version of the standard. 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.
