Standards may be obtained from appropriate standard authorities. Facing properties of sandwich constructions by long beam flexure, so called four point flexure.

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. 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.

The specimens are installed into the 4-point test fixture of the Universal Test Machine. Active view current version of standard. Send us a request Need help or have a question?

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Tests to evaluate core shear strength may also be used to evaluate core-to-facesheet bonds. 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.

Combining values from the two systems may result in nonconformance with the standard. 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. 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 f7249 subjected to pure edgewise in-plane compression.
