Calculate and report the average peel torque. This test method is used to compare adhesion between flexible and rigid adherends, or between flexible facing of a sandwich structure and its core. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specimens are placed in the climbing drum peel apparatus. 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. Historical Version s – view previous versions of standard. Testing can be complicated due to high adhesion strength and the dimensional rigidity of the core section, and the fact that the facing panels are not completely flexible.

Formally confirming that your products and services meet all trusted external and internal standards.
Aastm comparison of different adhesives or processes can only be made when specimen design and test conditions are identical. Samples need to be thick enough not to bend during test. Assurance Testing Inspection Certification. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.
Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. Climbing Drum Peel Fixture mm wide eccentric roller grip.
In order to peel the flexible material from the rigid backing material and accurately measure the peel strength, a special device called a climbing drum peel fixture shown is used. The corresponding amount of crosshead movement is dependent on the geometry of the climbing drum peel fixture.
The grips of a Universal Test Machine are initiated at a specified grip separation significant enough to roll the drum upward. Comparisons of adhesives and processes are only applicable when test specimens and conditions are the same.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. 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. For example it measures the peel resistance between: ASTM D determines the peel resistance of adhesive bonds between two materials with different physical properties.
These panels provide high stiffness and strength with low weight for aerospace and industrial applications. Dd1781 Formally confirming that your products and services meet all trusted external and internal standards. The standard speed is Apply a tensile load at a constant rate of crosshead separation and determine the average peeling load between 1in and 6in of adherend separation.
For adhesives in bonding metal-faced asrm construction, a facing of clad aluminum alloy meeting Specification B29, Alloy T3, 0. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. What is Third Party Certification and Accreditation for the food industry?
Link to Active This link will always route to the current Active version of the standard. For example it measures the peel resistance between:. Assurance Enabling you to identify and mitigate the intrinsic aatm in your operations, supply chains and business processes.
The peel resistance may indicate degree of cure for relatively brittle adhesives.
ASTM D1781 Climbing Drum Peel Testing
This test method is particularly sensitive to adherend surface preparation and is of value where the adhesive is used in conjunction with a primer. In each case the surface adherend is relatively flexible and the backing material is very rigid. The adhesive used for the sandwich panel construction is critical to ensure structural integrity. The values astn in parentheses are for information only. 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.
Enabling you to identify asgm mitigate the intrinsic risk in your operations, supply chains and business processes. We are happy to help! From climbing drum peel results the following calculations can be made: Sales Support Calibration Calculators. Validating the specifications, value and safety of your raw materials, products and assets.
