Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Inspection Validating the specifications, value and safety of your raw materials, x393 and assets. Permissible core material forms include astmm with continuous bonding surfaces as well as those with discontinuous bonding surfaces. By means of our sandwich construction testing expertise and modular product design, we will help find the testing solution that is right for you.
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. Formally confirming that your products and services meet all trusted external and internal standards. Link to Active This link will always route to the current Active version of the standard.
Combining values from the two systems may result in non-conformance with the standard.
ASTM C393 – Core Shear Properties Testing of Sandwich Constructions by Beam Flexure
The standard loading configuration is a 3-point configuration with a support span of mm [6. Wider load f393 with rubber pads may assist in distributing the loads. 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.
From 3-point loading results the following calculations can be made: Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb. Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds.
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 c339. The 4-point configuration is considered modified. Auditing Consulting Sourcing Training.
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. Select from list below: Validating the specifications, value and safety of your raw materials, products and assets. Send us a request Need help or have a question? 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 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. The test consists of three or four-point bending of the samples with load and deflection measurements.
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, astj and custom solutions for unique applications. 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.
Flexure tests on flat adtm construction may be conducted to determine the sandwich flexural stiffness, the core shear strength and shear modulus, or the facings compressive and tensile strengths.
