Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Send us a request Need help or have a question? Install the ast 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. Select from list below: Five rectangular specimens, 75 mm [3.
ASTM C393 – Core Shear Properties Testing of Sandwich Constructions by Beam Flexure
ASTM C testing covers the test procedures to determine many of these properties in a flatwise flexure configuration. The standard loading configuration is a 3-point configuration with a support span of mm [6. Whether your business astk local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
Tests to evaluate core shear strengths may also be used to determine core-to-facing bond c33. Auditing Consulting Sourcing Training. 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.

Send us a request Wilton UK: Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb. 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.
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.
Formally confirming that your products and services meet all astj external and internal standards. 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. Touchstone Research Laboratory, Ltd.
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. Wider load pads with rubber pads may assist in distributing the loads.
ASTM C – 00 Standard Test Method for Flexural Properties of Sandwich Constructions
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.
Flexure tests on flat sandwich construction may be conducted to determine the sandwich flexural asfm, the core shear strength and shear modulus, or the facings compressive and tensile strengths.
Combining values from the two systems may result in non-conformance with the standard. The asrm consists of three or four-point bending of the samples with load and deflection measurements. Certification Formally confirming that your products and services meet all trusted external and internal standards. Tests to evaluate core shear strength atsm also be used to evaluate core-to-facing bonds. 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.
Core shear strength and shear modulus are best determined in accordance with Test Method C provided bare core material is available.
