Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides ast and safety solutions to a wide range of industries around the world.
Wider load pads with rubber pads may assist in distributing the loads. Auditing Consulting Sourcing Training.
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.
Touchstone Research Laboratory, Ltd. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Core shear strength and shear modulus are best determined in accordance with Test Method C provided bare core material is available.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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. Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds.
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. Assurance Testing Inspection Certification. Aztm standard loading configuration is a 3-point configuration with a axtm span of mm [6. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: 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. Force range of 5 kN to kN 1, lbf to atsm, lbf 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.
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.
Core Shear Properties of Sandwich Constructions by ASTM C
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. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. ASTM Sstm testing covers the test procedures to determine many of these properties in a flatwise flexure configuration.
ASTM C Flexure tests on flat sandwich construction may be conducted to aetm the sandwich flexural stiffness, the core shear strength and shear modulus, or the facings compressive and tensile strengths. Tests to evaluate core shear strengths may also be used to determine core-to-facing bond strength. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. From 3-point loading results the following calculations can be made: Select from list below: Link to Active This link will always route to the current Active version of the standard.
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. Concentrated loads on sstm with thin facings and low density cores can produce results that are difficult to interpret, especially close to the failure point.
