Concentrated loads on beams with thin facings and low density cores can produce results that awtm difficult to interpret, especially close to the failure point. 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.

Core Shear Properties of Sandwich Constructions by ASTM C393

Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds. Tests to evaluate core shear strengths may also be used to determine core-to-facing bond strength. Historical Version s – view previous versions of standard. Many different properties can be determined from a f393 set of tests, such as sandwich flexural stiffness, the core shear strength and shear modulus, and facing strength.

The test method ASTM C determines flexural strength, core shear strength and facings compressive and tensile strengths in the direction the core would be placed in a structural construction.

ASTM C determines the core shear properties of flat sandwich constructions subjected to flexure in such a manner that the applied moments produce curvature of the sandwich facing planes. Have a question about conducting the test for this standard?

The test consists of three or four-point bending of the samples with load and deflection measurements. Certification Formally confirming that your products and services meet all trusted external and internal standards.

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.

Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb. Wider load pads with rubber pads may assist in distributing the loads. Formally confirming that your products and services meet all trusted external and internal standards. Install the conditioned specimens if required into a 3-point or 4-point loading fixture on the Universal Test Machine and initiate at a specified grip separation significant enough to produce failure within 3 to 6 minutes.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Sandwich constructions are increasingly being used as high-strength, light-weight components, and therefore, standard test methods are being developed and used to determine critical properties and strength assessments.

ASTM C testing covers the test procedures to determine many of asmt properties in a flatwise flexure configuration. We are confident that we have what you are looking for. Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces axtm as honeycomb.
