The back jaw must be at least 1×2″. 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.

As a minimum, the two parties should take a group of test specimens from the same lot of d1863 to be evaluated, which utilize a like seam assembly or standard seam assembly.

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 1d683 seam can be changed to use the Lapped seam type construction with two or more rows of stitching: Referenced Documents purchase separately The documents listed below are referenced within the subject standard asttm are not provided as part of the standard.

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. Active view current version of standard. Sewn seams in woven aetm can fail due to rupture, slippage, or any combination thereof. This test requires specialized grip jaws inserts.

The seam strength is divided by the ultimate strength in order to give a percentage. 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.

ASTM D1683 Fabric Seam Strength Testing

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The front of the grip jaw is xstm be 1×1″ or Note 2—This test method is used in conjunction with Test Method Dwhich is used to measure breaking force asmt elongation of textile fabrics.

This ASTM test requires Vise Grips to be used, however in some rare cases, wrap grips can also be used however this should be noted on the test. Size Metric 90 [0. The analysis for seam strength or seam efficiency is calculated by dividing the seam strength by the ultimate tensile strength of the base material without a seam.

ASTM D – Seam Strength Testing

When the failure results in e1683 of yarns, the textile product will need to be replaced. Lsc-2; Lsc-3; Lsc-4; and the maximum number of stitches per inch that can be used. The specimen is pulled in tension, similar to a grab test, until it breaks. Universal Grip offers several different types of vise grips depending on the total load required for the test.

Rupture can be further categorized as failure or fabric, or sewing thread, or seam slippage. Pneumatic Vise Grips are also available along with all of the accompanying awtm and switches.

Combining values from the two systems may result in non-conformance with the standard. Seam strength is a comparison test between an unseamed test piece of fabric and the seamed fabric specimen. 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. Pneumatic Grips are a great way to speed up testing by reducing the time it takes to mount the samples in between test lots.

Combining values from the two systems may result in non-conformance with the standard. Table 1 lists the default seam assembly specifications to be used for fabrics made with fine, medium and heavy count yarns. 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.
