Calculate and report the average peel torque.
Specimens are placed in the climbing drum peel apparatus. 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. Need help or have a question?
ASTM D1781 Climbing Drum Peel Testing
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. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Send us a request Wilton UK: Direct comparison of different adhesives or processes can only be made when specimen design and test conditions are identical. From climbing drum peel results the following calculations can be made: Standards can be obtained from appropriate standard authorities.
Samples need to be thick enough not to bend during test. The adhesive used for the sandwich panel construction is critical to ensure structural integrity. Formally confirming that your products and services meet all trusted external and internal standards.
Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.
For example it measures the peel resistance between:. Certification Formally confirming that your products and services meet all trusted external and internal d1718. 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.
Historical Version s – view previous versions of standard Translated Version s: The corresponding amount of crosshead movement is dependent on the geometry of the climbing drum peel fixture.
Climbing Drum Peel Fixture mm wide eccentric roller grip. The grips f1781 a Universal Test Machine are initiated at a specified grip separation significant enough to roll the drum upward.
This test method is used to compare adhesion between flexible and rigid adherends, or between flexible facing of a sandwich structure and its core. 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.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Link to Active This link will always route to the current Active version of the standard. 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.
Inspection Validating atsm specifications, value and safety of your raw materials, products and assets.
Work with us to find the right equipment for your ASTM standard. Auditing Consulting Sourcing Training. 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 example it measures the peel resistance between: 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.
Historical Version s – view previous versions of standard.
In each case the surface adherend is relatively flexible and the backing material is very rigid. ASTM D determines the peel resistance of adhesive bonds between two materials with different astmm properties.
What is Third Party Certification and Accreditation d1718 the food industry? These panels provide high stiffness and strength with low weight for aerospace and industrial applications.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The values given in parentheses are for information only. Send us a request Need help or have a question? For laminates, 25 mm [1 in] wide between saw kerfs by at least mm [10 in].
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The standard speed is This test method is particularly sensitive to adherend surface preparation and is of value where the adhesive is used in conjunction with a primer.
