The grips of a Universal Test Machine are initiated at a specified grip separation significant enough to roll the drum upward. From climbing drum peel results the following calculations can be made: When a relatively brittle adhesive is used, the peel resistance can often give an indication of the degree of cure, that is, higher values than normally realized may indicate an incomplete cure.

This test method is used to compare adhesion between flexible and rigid adherends, or f1781 flexible facing of a sandwich structure and its core.

dd1781 If test results are to be used only for comparative test to test purposes, then this error testing is not necessary because the errors are the same in each test and therefore negate each other. Historical Version s – view previous versions of standard.

These errors can both be compensated out of the test by running the test on one or more dummy specimens which have the same flexible adherand but no adhesive. For adhesives in bonding metal-faced sandwich construction, a facing of clad aluminum alloy meeting Specification B29, Alloy T3, 0. We also recommend that you purchase the ASTM D standard and follow it closely to achieve the best results. Specimens are placed in the climbing drum peel apparatus.

The resulting force profile can be x1781 from the actual test data point by point to determine the force generated by the adhesive in the peel. For this test, our engineers also recommend a GG manual vice grip.

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

This fixture is made specifically to ASTM D and consists of a flanged drum, flexible loading straps, and specified clamps for holding the test specimen. This test method is particularly sensitive to adherend surface preparation and is of value where the aatm is used in conjunction with a primer. This allows you to quantifiably compare each process condition.

Auditing Consulting Sourcing Training. This test method may be used to determine comparative rather than fundamental measurements of adhesion and is particularly suitable for process control, some examples of which are listed. ASTM D is a standard test to determine the peel resistance of adhesive bonds on products that have a flexible adherand and a rigid adherand surface.

A test can also be performed on a dummy specimen, which is the same as a test specimen but has no adhesive, in order to quantify the force errors in the test setup. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

Have a question about conducting the test for this standard? Due to the errors in the peel force caused ast the force to lift the drum and force to bend the flexible adherand around the drum, this standard is less popular than other peel testing standards and is typically used for comparative testing in process control and process optimization situations.

Direct comparison of different adhesives or processes can only be d171 when specimen design and test conditions are identical.
