Combining values from the two systems may result in non-conformance with the standard. Sandwich constructions are increasingly being used asstm high-strength, light-weight components, and therefore, standard test methods are being developed and used to determine critical properties and strength assessments.

Need help or have a question? Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. 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.

ASTM C testing covers the test procedures to determine many of these properties in a flatwise flexure configuration.

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 standard loading configuration is a 3-point configuration with a support span of mm [6. 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.

The test consists of three or four-point bending of the samples with load and deflection measurements. Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb.

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.

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.

Standards can be obtained from appropriate standard authorities.

Tests to evaluate core shear strengths may also be used to determine core-to-facing bond strength. 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? 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. From 3-point loading results the following calculations can be made: Validating the specifications, value and safety of your raw materials, products and assets. Permissible core material forms include those with continuous bonding surfaces as well as those with discontinuous bonding surfaces.
