Elongation The elongation is typically measured by the crosshead of the UTM, however extensometers can be used to acquire direct strain data from the specimen.

ASTM D – 06() Standard Test Methods for Coated Fabrics

This special crush resistance fixture is unique to this test. You will need a specialized tack-tear resistance fixture shown in Figure 4 of the standard official standard. Preparing the Specimens for the Tongue Tear Method Five specimens from each of the warp and filling directions should be tested. The bursting strength test determines the bursting strength of the coated fabric.

Dead Load Seam Strength is similar to the seam strength test.

ASTM D Coated Fabrics Rainwear Test Equipment

The oven only cycles heat, the samples should not be exposed to light. Procedure A is the preferred method to test, but Procedure B is also acceptable. Preparing the Specimens Five specimens should be cut with the smallest dimension at least Preparing the Specimens Use the same specimens as for breaking strength. Place the load button on the test specimen with the recessed end down and at least 12 mm from any edge of the specimen.

The sstm grip faces must be 1×2″ HxW or more. After the sample has been heat aged it is tested using one of the above procedures.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. Accelerated Heat Aging Oven Method. Preparing the Specimens The adhesion of coating to fabric xstm in ASTM D requires two sets of two specimens each for the longitudinal and transverse direction.

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.

Record the force necessary to separate the coating from the backing. Crush resistance is a compression test similar to a atsm test. Low Temperature Bend Test. The adhesion of coating to fabric test in ASTM D requires two sets of two specimens each for the longitudinal and transverse direction. S751 weight is measured on a asrm with a smaller piece of the fabric. Apply the force to the button with a uniform speed of.

After a set period of time the amount of wicking is measure. Test Procedure First you should mount the test specimen in the ring clamp.

The apparatus is then pulled apart and tearing occurs along where the needles were gripped into the sample. Tack-Tear Resistance The Tack-Tear test fixture is described in scant detail in the official publication. The seam strength test works great for lapped, lapped and bonded, and sewn seams using the modified grab test method.

Preparing the Specimens Three specimens should be tested. Preparing the Specimens Ten specimens should be cut with the dd751 dimension at least Crush Resistance Crush resistance is a compression test similar to a shear test. Low Temperature Crack Resistance Crack resistance is tested at low temperature by means of a chilling chamber.

Testing Procedure Clamp the specialized fixture device in the upper clamp of the test machine and adjust the machine to compensate for its weight.

ASTM D specifies the low temperature bend test. A UTM and vise grips with the same 1×1 and 1×2 inserts are used. The long term increases in productivity and efficiency out-weigh the initial cost. Create two sets of five specimens each for warp and filling tack-tear strength. The sample is stretched at a definied load for a set period of time before being hydrostatically tested.

This test is used to determine compare the seam asym with the strength of the coated fabric. Types of coatings that are commonly used include plastic material as well as teflon PTFE. The Tack-Tear test fixture is described in scant detail in the official publication. Tests within D include puncture, seam strength, and tear tests.

This test determines the tack-tear resistance of the coated fabric. Once the samples are cold enough, the samples are folded in half. Dead Load Seam Strength. This test is characterized by a spherical plunger fixture. This test determines the puncture resistance of the coated fabric. ASTM D covers a similar procedure for seam efficiency. Call our fixture engineers today and they can provide asfm with a specialized fixture just for this test.
