ASTM C testing covers the test procedures to determine many of these properties in a flatwise flexure configuration. Historical Version s – view previous versions of standard.
Certification Formally confirming that your products and services meet all trusted external and internal standards. 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. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.
ASTM C393 TESTING FIXTURE
Historical Version s – view previous versions of standard Translated Version s: Need help or have a question? 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. Auditing Consulting Sourcing Training.
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. Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb. 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.
The 4-point configuration is considered modified. Standards can be obtained from appropriate standard authorities. Permissible core material forms include those 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. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: 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. Select from list below: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Tests to evaluate core shear strengths may also be used to determine core-to-facing bond strength.
Work with us to find the right equipment for your ASTM standard. Core shear strength and shear modulus are best determined in accordance with Test Method C provided bare core material is available.
Satm Reach Intertek is the industry leader with over 43, people in 1, locations in over countries. Combining values from the two systems may result in non-conformance with the standard. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The shear properties are determined via a bend test in a 3- or 4-point loading condition. Send us a request Wilton UK: Sales Support Calibration Calculators.

From 3-point loading results the following calculations can be made: Wider load pads with rubber pads may assist in distributing the loads.
ASTM C Flexure tests awtm 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. ASTM C is a test method designed to determine the core shear properties of sandwich constructions. Send us a request Need help or have a question? The standard loading configuration is a 3-point configuration with a support span of mm [6.
We’re happy to help! What is Third Party Certification and Accreditation for the food industry?
ASTM C Bend Fixture | GC
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Five rectangular specimens, 75 mm [3.
Insert and carefully align the test specimen within the fixture. 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.
Apply a compressive load to the specimen using a constant rate of displacement according to the standard. Give one of our application engineers a call today for help with creating the astmm budget and testing plan according to ASTM C 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.
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.
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. C33 loads on beams with thin facings and low density cores can produce results that are difficult to interpret, f393 close to the failure point.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Validating the specifications, value and safety of your raw materials, products and assets. Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds. This test standard requires a very unique articulating bend fixture with pressure pads to help provide the most accurate and consistent core shear results possible, even with the sometimes difficult to control process of manufacturing sandwich constructions.
