ASTM D1781 PDF

Zulkishicage Standards can be obtained from appropriate standard authorities. 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. Comparisons of adhesives and processes are only applicable when test specimens and conditions are the same. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of d frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more. The peel resistance may indicate degree of cure for relatively brittle adhesives.

This standard can also be used for testing a sandwich structure and its core by pulling the facing off the sandwich assembly. ASTM D is most often used in A-B comparison testing: to compare the results of two different process conditions for the sake of optimizing a process.

Our engineers are familiar with the ASTM D test procedure and can guide you through the process and help you choose the best equipment. We also recommend that you purchase the ASTM D standard and follow it closely to achieve the best results. This allows you to quantifiably compare each process condition. 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.

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. Next, secure the rigid adherand into a manual vice grip. The minimum data should be average peel force over six inches.

A raw data plot is also useful to view the peel plot data. 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.

The resulting force profile can be subtracted from the actual test data point by point to determine the force generated by the adhesive in the peel. Due to the errors in the peel force caused by 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. Recommended Test Equipment The peel plot will be an important aspect of data retrieval and therefore we highly recommend our XyPlot software.

If you would rather see the data in real-time and study the peel interface at the same time, we would provide you with our XyLive Software. The P consists of a vertical load frame, an electromechanical actuator, load cell, a tocuhpad test controller, XY test software and a climbing peel drum fixture.

For ASTM D, we would configure a small capacity load cell 10 or 25 pound for this low force peel test. A 10 lb load cell can be calibrated to measure 0. 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. For this test, our engineers also recommend a GG manual vice grip. Give one of our engineers a call today and they can help guide you through the ASTM D test process with the best machine configuration for your requirements.

Recommended Test Machine 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 Force range of 5 kN to kN 1, lbf to , lbf 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 Recommended Testing Accessories Designed in accordance to ASTM D Drum diameter of mm 3.

Simple yet strong design can be used for a multitude of tensile applications Works well with flat or round specimens.
