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.

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.
