Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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 method provides information on the force-deflection behavior of sandwich constructions or cores when loaded in shear parallel to the plane of the facings. It is the responsibility of the user of this ast, to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Combining values from the two systems may result in non-conformance with the standard. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
ASTM C273 – Shear Properties Testing of Sandwich Core Materials
Certification Formally confirming that your products and services meet all trusted external and internal standards. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
The test may be conducted on core materials bonded directly to the loading plates or the sandwich facings bonded to the plates. Intertek currently only has the capabilities to perform the compression method. Core Shear ASTM C Shear Strength and Modulus Sandwich Atm, identification of compression or tension characteristics of composites by ASTM C This test method is used to determine core shear cc273 of a sandwich construction material using loading plates bonded to the outer surfaces or skins facesheets.
Historical Version s – view previous versions of standard. Formally confirming that your products and services meet all trusted external and internal standards.
From a complete force-deflection curve, it is possible to compute core shear stress at any force such as the shear stress at proportional limit, at yield, or at maximum force and to compute an effective core shear modulus.

ASTM C A TESTING FIXTURE
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The test is applicable for either continuous foams or discontinues bonding surfaces honeycomb. The values stated c2773 each system may not be exact equivalents; therefore, each system shall be used independently of the other. The bonded loading plates are either pulled in tension or pushed in compression on a Universal Test Machine in order to shear the material within 3 to 6 minutes.
Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb.

Approximate shear properties can also be obtained from a sandwich flexure test see Test Method C Composites Testing Shear Asrm. It covers the determination of shear strength parallel to the plane of the sandwich, and the shear modulus associated with strains in a plane normal to the facings. This test method is used to determine core shear properties of a sandwich construction material using loading plates bonded to the outer surfaces or skins facesheets.
