Concrete, Asphalt and Rock. Grip that layer of the specimen of which the adhesion is to be tested symmetrically and firmly without twisting in the power-actuated clamp.

Serrated jaw faces are zstm used for metal or rigid materials and smooth or rubber coated jaw faces are used for softer materials. Some systems claim to offer high data rates but have a limited data buffer which limits the test time. Rated to N 50 lbf Maximum specimen thickness of 8 mm 0. Discover simpler and smarter testing with features such as pre-loaded test methods, Aastm in seconds, enhanced data exporting: Email addresses must contain the symbol.

Subscribe to Instron News! Rated to 1 kN lbf Maximum specimen thicknesses from 10 mm to 50 mm 0. Email addresses must contain the symbol. Strip the separating layer from the specimen at astk angle of approximately degree, and continue the separation for a sufficient distance to indicate the adhesion value. Glossary of Materials Testing Terms.

The resulting graph is representative of a tear separation of several inches, with peaks and valleys of force along the way.

As covered by ASTM D, an adhesion test consists of applying to a test specimen a measured force sufficient to strip from the specimen at a measured rate, a layer of moderate thickness with separation rupture, tearing at the adhered surfaces. Peel along the previously cut separation layer for 40 to mm. Separate the parts to be tested by hand at one s413 of the test specimen and at a sufficient distance to permit grips of the machine to be attached.

With the mandrel attached to the recording head of the machine and the separated layer gripped symmetrically and firmly without twisting in the power-actuated clamp, and start the machine.

ASTM D413 Peel Adhesion of Rubber to Flexible Substrate

Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. High, uniform data acquisition rates coupled with a proper bandwidth provide the best results. By means of our extensive testing expertise and modular product design, we will help configure the testing solution that is right for you. An improper bandwidth can either introduce system noise or filter out actual test data points – all of f413 can lead to inaccurate test results.

However, once a product is established, minimum values of separation force can be determined and agreed to by producer and consumer and both can monitor to assure maintenance of the agreed-upon minimum value.

We are confident that we have what you are looking for. Onsite Training At Your Facility.

ASTM D applies when the adhered surfaces astj approximately plane or uniformly circular as in belting, hose, tire carcasses, or rubber-covered sheet metal. How can we help you?


Instron ASTM D Rubber Property – Instron

With our test machine, the rate of separation is fixed and the adhesion value is expressed in terms of the measured force. During the test, the mandrel shall rotate freely so as to maintain the line of separation at all times approximately in the same position.

Place wstm specimen snugly on the test mandrel. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! How can we help you? The test involves taking a strip of aastm with both layers bonded together, initiating an artificial “tear”, or separation at one end of the strip, inserting these free ends into a set of grips, and pulling the layers apart.

Next Checking to see if you are a returning visitor…. The value of interest is the Adhesion Strength – defined as d431 average force divided by the width of the specimen. Our universal testing machines can be used to perform the method described in this standard. Simple design can be used for a multitude of tensile applications Inexpensive and reliable. In peel tests, the data acquisition rate is critical for repeatable and accurate results. This ensures that the line of tensile force remains concentric with the grip body.

WaveMatrix 2 for Dynamic Testing. Provide for maintaining the strip during the test approximately in the plane of the clamps. The standard defines three types of specimens:
