The specimens are installed into the 4-point test fixture of the Universal Test Machine. Certification Formally confirming that your products and services meet all trusted external and internal standards. Send us a request Wilton UK: The test provides information on sandwich flexural stiffness, core shear strength, shear modulus, facing compressive strength and facing tensile strength.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Auditing Consulting Sourcing Training.

Facing properties of sandwich constructions by long beam flexure, so called four point flexure. Link to Active This link will always route to the current Active version of the standard. Standards may be obtained from appropriate standard authorities. Historical Version s – view previous versions of standard. Inspection Validating the specifications, value and safety of your raw materials, products and assets. Concentrated forces on beams with thin facesheets and low density cores can produce results that are difficult to interpret, especially close to the failure point.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Combining values from the two systems may result in nonconformance with the standard. Validating the specifications, value and safety of your raw materials, products and assets. Five specimens tested at thickness. Permissible c7249 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.

Bonded strain gages are applied to the specimens if applicable. 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.

Due to the curvature of the flexural test specimen when loaded, facesheet compression strength from this test may not be equivalent to the facesheet compression strength of sandwich structures subjected to pure edgewise in-plane compression. Need help or have a question?
