Historical Version s cc393 view previous versions of standard Translated Version s: Link to Active This link will always route to the current Active version of the standard. 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.

Permissible core material forms include those with continuous bonding surfaces as well as those with discontinuous bonding surfaces. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

ASTM C393 Flexural Sandwich Composites Test Equipment

Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb. Combining values from the two systems may result in non-conformance with c3393 standard. Auditing Consulting Sourcing Training. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.

ASTM C Bend Fixture | GC

The standard loading configuration is a 3-point configuration with a support span of mm [6. The 4-point configuration is considered modified.


Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds. Have a question about conducting the test for this standard?


Core shear strength and shear modulus are best determined in accordance with Test Method C provided bare core material is available. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. By means of our sandwich construction testing expertise and modular product design, we will help find the testing solution that is right for you. 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.

Tests to evaluate core shear strength may also be used to evaluate 3c93 bonds. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Need help or have a question? The astmm 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.
