Direct comparison of different adhesives or processes can only be made when specimen design and test conditions are identical. Inspection Validating the specifications, value and safety of your raw materials, products and assets. For example it measures the peel resistance between:.

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. Certification Formally confirming that your products and services meet all trusted external and internal standards. 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 Specimens are placed in the climbing drum peel apparatus.

ASTM D1781 TESTING FIXTURE

Need help or have a question? For adhesives in bonding metal-faced sandwich atsm, a facing of clad aluminum alloy meeting Specification B29, Alloy T3, 0. Apply a tensile load at a constant rate of crosshead separation and determine the average peeling load between 1in and 6in of adherend separation. Assurance 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. 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. Samples need to be thick enough not to bend during test. 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.

From climbing drum peel results the following calculations can be made: ASTM D determines the peel resistance of adhesive bonds between two materials with different physical properties. Standards can be obtained from appropriate standard authorities. Auditing Consulting Sourcing Training. These panels provide high stiffness and strength with low weight for aerospace and industrial applications.

Climbing Drum Peel Fixture mm wide eccentric roller grip. What is Third Party Certification and Accreditation for the food industry?

For laminates, 25 x1781 [1 in] wide between saw kerfs by at least mm [10 in]. 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.

This test astk is used to compare adhesion between flexible and rigid adherends, or between flexible facing of a sandwich structure and its core. The corresponding amount of crosshead movement is dependent on the geometry of the climbing drum peel fixture.

ASTM D – 98() Standard Test Method for Climbing Drum Peel for Adhesives

Calculate and report the average peel torque. The peel resistance may indicate degree of cure for relatively brittle adhesives. Sales Support Calibration Calculators. Work with us to find the right equipment for your ASTM standard. 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.

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. Link to Active This link will always route to the current Active version of the standard.

The adhesive used for the sandwich panel construction is critical to ensure structural integrity. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. For example it measures the peel resistance between: The grips of a Universal Test Machine are initiated at a specified grip separation significant enough to roll the drum upward.

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. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

This test method is particularly sensitive to adherend surface preparation and is of value where the adhesive is used in conjunction with a primer.
