Give one of our application engineers a call today for help with creating the best zstm and testing plan according to ASTM D Type C is for ring specimens. Onsite Training At Wstm Facility. This ensures that the line of tensile force remains concentric with the grip body. Software for Series Systems.
The dual – acting design of series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses. How can we help you?

ASTM D applies when the adhered surfaces are approximately plane or uniformly circular as in belting, hose, tire carcasses, or rubber-covered sheet metal.
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.
ASTM D determines the adhesion strength required to separate a rubber layer from a flexible substrate such as a fabric, fiber, or sheet metal. Separate the parts to be tested by hand at one end of the test specimen and at a sufficient distance to permit grips of the machine to be attached.
Rated to N 50 lbf Maximum specimen thickness of 8 mm 0.
ASTM D413 Peel Adhesion of Rubber to Flexible Substrate
An improper bandwidth can either introduce system noise or filter out actual test data points – all of which can lead to inaccurate test results. 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.
Please confirm that you agree with our privacy and cookies policy to submit this form. The resulting graph is representative of a tear separation of several inches, with peaks and valleys of force along the way. Email addresses must contain the symbol.
Grip that layer r413 the specimen of which the adhesion is to be tested symmetrically and firmly without twisting in the power-actuated clamp. The appropriate load string would typically consist of flat faced grips – mechanical or pneumatic, and a load cell properly sized to capture the forces involved – usually between 5 and 50 lbf N.
Place the specimen snugly on the test mandrel. The value of interest is the Adhesion Strength – defined as the average force divided by the width of the specimen.
The acceptable value of adhesion measured will, of course, vary from product to product due to different rubber formulations, flexible substrates, and types of products. 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 s413 assure atsm of the agreed-upon minimum value.
ASTM D – 98() Standard Test Methods for Rubber Property—Adhesion to Flexible Substrate
astmm Rated to 1 kN lbf Maximum specimen thicknesses from 10 mm to 50 mm 0. They can be equipped with a selection of interchangeable grip jaw faces in various sizes and choice of surfaces including smooth ground, rubber-coated and serrated.
Separate by hand a sufficient distance along the separation line in the center of the strip to permit the grips of the machine to be attached.
