Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C From 3-point loading results the following calculations c93 be made: Auditing Consulting Sourcing Training.
Validating the specifications, value and safety of your raw materials, products and assets. Select from list below: Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb. 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.
ASTM C393 TESTING FIXTURE
ASTM C determines the core shear properties of flat sandwich constructions subjected to flexure in such a manner that the applied moments c33 curvature of the sandwich facing planes. ASTM C testing covers the test procedures to determine many of these properties in a flatwise flexure configuration. Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Have a question about conducting the test for this standard? The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.
Tests to evaluate aastm shear strength may also be used to evaluate core-to-facing bonds.
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. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Standards can be obtained from appropriate standard authorities. Historical Version s – view previous versions of standard. Referenced Documents purchase separately The documents listed below are referenced x393 the subject standard but are not provided as awtm of the standard. We are confident that we have what you are looking for. 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.
ASTM C – 00 Standard Test Method for Flexural Properties of Sandwich Constructions
Historical Version s – view previous versions of standard Translated Version s: Wider load pads with rubber pads may assist in distributing the loads. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. 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.
Five rectangular specimens, 75 mm [3. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Inspection Validating the specifications, value and safety of your raw materials, products and assets. Permissible core material forms include those with continuous bonding surfaces as well as those with discontinuous bonding surfaces.
Touchstone Research Laboratory, Ltd. 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. Tests to evaluate core shear strengths may also be used to determine core-to-facing bond strength.
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.
