Specification ASTM D includes test methods for covering a wide range of mechanical properties of coated fabrics. ASTM D is used to ensure the quality of rubber-coated fabrics including tarpaulins, rainwear, outdoor clothing, and similar products. ASTM D features . 9 Sep This standard is issued under the fixed designation D ; the 1 These test methods are under the jurisdiction of ASTM Committee D11 on.

The adhesion test is used when the coating is stronger than the adhesive that binds it to the fabric. Types of coatings that are commonly used include plastic material as well as teflon PTFE. The idea is to test for any cracks in the coating that may affect its permeability.
Small wick sized samples are put into a beaker with a water soluble dye. Use the same aetm as for breaking strength. D Seam Strength This test is used to determine compare the seam strength with the strength of the coated fabric.
Preparing the Specimens Gather two sets of 5 specimens each d715 longitudinal and transverse breaking strength. A UTM and vise grips with the same 1×1 and 1×2 inserts are used.
This test is applicable to diaphragm material cut from coated fabrics that will be used for automotive and regulator devices. 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. Cuts test specimens from stock material Available for a wide variety of ISO and ASTM standards Consistent specimens for consistent results Manufactured with tool steel to resist damage and wear over time.
This test determines the tack-tear resistance of the coated fabric. Puncture Resistance Another test using a puncture fixture.
ASTM D751 Coated Fabric Tensile Testing
This will be recorded by the UTM controller. Test Procedure First you should mount the test specimen in the ring clamp. Crack resistance is tested at low temperature by means of a chilling chamber.
Another test using a puncture fixture.

The remaining sample is then tested for Hydrostatic Resistance. We are happy to help! Elongation Test is done at the same time as the breaking strength test so grips are the same. d571
Vise grips with 25mm, 50mm, 75mm wide jaw faces Burst fixture with both round and sharp noses Tack-tear fixture Crush resistance test fixture. Seam Strength Same grips as described in Adhesion Coating to Fabrics test Dead Sstm Seam Strength Same vise grips as specified in the other tests Crush Resistance This test deflects the material over a button shaped compression platen until the material is crushed or cut.
The strength of the coating on the fabric is measured by pretensioning the sample and astmm testing it using one of the above hydrostatic methods.
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. After the sample has been heat aged it is tested using one of the above procedures. ASTM D specifies the low temperature bend test.
Blocking Resistance at Elevated Temperatures Blocking resistance is tested by folding a piece of fabric sample a couple of times and then placing it in between two glass plates. Blocking Resistance at Elevated Temperatures. ADMET universal testing machines include the straining mechanism item 1 and built in load and elongation recording mechanisms Item 3.
ASTM D Coated Fabric Tensile Testing – ADMET
A tensile tester and vise grips with 2×3″ HxW grip inserts are used. After a set period of time the amount of wicking is measure. Specimens should be in rectangle shapes and should be 50mm W X mm L with the seam horizontally across the center. Forces up 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.
Record the force necessary for the sample to slip the seam or rupture the fabric. Waterproof textiles are also usually tested to one or more of these standards.
