ASTM C is a testing specification that determines the shear properties of sandwich construction core materials associated with shear distortion of planes. This standard is issued under the fixed designation C ; the number immediately 1 This test method is under the jurisdiction of ASTM Committee D30 on. ASTM C B TESTING FIXTURE. SHEAR PROPERTIES OF SANDWICH CORE MATERIALS. 1. ASTM C B – Testing-Fixture. A sandwich panel or the core.

The test is applicable for either continuous foams or discontinues bonding surfaces honeycomb.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

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

Core Shear ASTM C
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.
Intertek currently only has the capabilities to perform the compression method. Need help or have a question? Approximate shear properties can also be obtained from a sandwich flexure test see Test Method C Auditing Consulting Sourcing Training. This test method provides information on the force-deflection behavior of sandwich constructions or cores when ast in shear parallel to the plane of awtm facings.
Formally confirming that your products and services meet all trusted external and internal standards.
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.

Cc273 your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any c2273 around the world. 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.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over c723. Work Item s – proposed revisions of this standard. 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. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM C273 – Shear Properties Testing of Sandwich Core Materials
The test may be conducted on core materials bonded asfm to the loading plates or the sandwich facings bonded to the plates. Combining values from the two systems may result in non-conformance with the standard.
