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.

The 4-point configuration is considered modified. Historical Version s – view previous versions of standard Translated Version s: Select from list below: Send us a request Need help or have a question? Historical Version s – view previous versions of standard.

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.

Need help or have a question? Core shear strength and shear modulus are best determined in accordance with Test Method C provided bare core material is available.

Touchstone Research Laboratory, Ltd. Assurance Testing Inspection Certification. Wider load pads with rubber d393 may assist in distributing the loads. 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 C393 Flexural Sandwich Composites Test Equipment

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. Validating the specifications, value and safety of your raw materials, products and assets. 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.

ASTM C TESTING FIXTURE

Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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. 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.

Five rectangular specimens, 75 mm [3. From 3-point loading results the following calculations can be made: Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: By means of our sandwich construction testing expertise and modular product design, we will help find the testing solution that is right for you.

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.
