Many different properties can be determined from a single set of tests, such as sandwich flexural stiffness, the core shear strength and shear modulus, and facing strength. Combining values from the two systems may result in non-conformance with the standard.
Core shear strength and shear modulus are best determined in accordance with Test Method C provided bare core material is available. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

ASTM C393 – Core Shear Properties Testing of Sandwich Constructions by Beam Flexure
Flexure tests on flat sandwich construction may be conducted to determine the sandwich flexural stiffness, the core shear strength and shear modulus, or the facings compressive and tensile strengths.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. 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.

Concentrated loads on beams with thin facings and low density cores can produce results that are difficult to interpret, especially close to the failure point.
Core Shear Properties of Sandwich Constructions by ASTM C
The test consists of three or four-point bending of the samples with load and deflection measurements. From 3-point loading results the following calculations can be made: Five rectangular specimens, 75 mm [3.

ASTM C – 00 Standard Test Method for Flexural Properties of Sandwich Constructions
Install the conditioned specimens if required into a 3-point or 4-point loading fixture on the Universal Test Machine and c33 at a specified grip separation significant enough to produce failure within 3 to 6 minutes. Certification Formally confirming that your products and services meet all trusted external and internal standards.
The standard loading configuration is a 3-point configuration with a support span of mm [6. The 4-point configuration is considered modified.
