Seam Strength shall be the median of all the individual results. Wicking of Coated Cloth.

Test Procedure First center the specimen in the machine with one tongue fastened in d7751 clamp Start the machine with a uniform speed of. This test is similar to ASTM D where a puncture implement with a chamfered edge is used to puncture through the sample. Puncture Resistance Another test using a puncture fixture. Due to the wide variety of test procedure in ASTM D, our test engineers recommend you purchase a universal test machine. This test determines the elongation of the coated fabric during the breaking asrm tests.

Preparing the Specimens Create two sets of five specimens each for warp and filling tack-tear strength. After the sample has been heat aged it is tested using one of the above procedures.

Five specimens should be cut with the smallest dimension at least We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

The oven only cycles heat, the samples should not be exposed to light.

Testing Procedure First clamp the separated portions of your sample in the jaws so that movement of the test machine will separate the coating from the backing. Tests include breaking strength by Procedure A: The test utlizes a tensile testing machine and a pair of vise grips with front grip inserts of 1×1″ and back inserts of 1×2″.

Test Procedure First, mount the test specimen in the ring clamp. Blocking resistance dd751 tested by folding a piece of fabric sample a couple of times and then placing it in between two glass plates.

The apparatus is then pulled apart and tearing occurs along where the needles x751 gripped into the sample.

Call our fixture engineers today and they can provide you with a specialized d7551 just for this test. There are a total of zstm procedures listed, with most of them being variations of common fabric tests.

Crush resistance is a compression test similar to a shear test. Specimens should be in rectangle shapes and should be 50mm W X mm L with the seam horizontally across the center.

There are a few types of grip faces that are available including blank, vulcanized rubber, pyramid, or wave. Call our engineers today for help testing to ASTM D and for help choosing the best test equipment. ASTM D is used to ensure the quality of rubber-coated fabrics including tarpaulins, rainwear, outdoor clothing, and similar products.

ASTM D specifies the low temperature bend test. XyLive Software allows you to watch the data live as the test runs. Testing Procedure First place the specimen symmetrically in the jaws of the grips with the seam centered between the jaws.

This type of test is also referred to as a Suter test. Cut Strip Test, Elongation, Burst strength, puncture resistance, tear strength tongue teartrapezoidal tear, Adhesion coating to fabric, tack tear resistance, seam strength, dead load seam strength, and crush resistance. Preparing the Specimens The adhesion of coating to fabric test in ASTM D requires two sets of two specimens each for the longitudinal and transverse direction.

Preparing the Specimens Use the same specimens as for breaking strength. Tests within D include puncture, seam strength, and tear tests.

ASTM D – Coated Fabrics

The idea is to test for any cracks in the coating that may affect its permeability. Adhesion Coating to Fabrics. Ten specimens should be cut with the smallest dimension at least Rated to 8 kN 1, lbf Clamping force up to 16 kN 3, lbf Maximum specimen thicknesses from 10 mm to 30 mm 0.
