Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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. Need help or have a question? Assurance Testing Inspection Certification.
Many different properties can be aastm from a single set of tests, such as sandwich flexural stiffness, the core shear strength c3993 shear modulus, and facing strength. Continue the application of force until the specimen fails, or the deflection is equal to the specimen thickness. Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.
ASTM C393 Bend Fixture | GC393
Standards can be ashm from appropriate standard authorities. The ast stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Care should be taken to modify the bend fixture pads, as necessary based on specimen construction, to try and prevent core crushing or facing panel failures during test.
Combining values from the two systems may result in non-conformance with the standard. ASTM C 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.
Five rectangular specimens, 75 mm [3. Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Formally confirming that your products and services meet all trusted external and internal standards.
By means of our sandwich construction testing expertise and modular product design, we will help find the testing solution that is right for you. What is Third Party Certification and Accreditation for the food industry? Record the force and deflection data.

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. Link to Active This link will always route to the current Active version of the standard.
Apply a compressive load to the specimen using a constant rate of displacement according to the standard. Insert and carefully align the test specimen within the fixture. 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. 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.
Tests to evaluate core shear strengths may also be used to determine core-to-facing bond strength. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
ASTM C – 00 Standard Test Method for Flexural Properties of Sandwich Constructions
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.
Certification Formally confirming that your products and services meet all trusted external and internal standards.
