Formally confirming that your products and services meet all trusted external and internal standards. Auditing Consulting Sourcing Training.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. 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.
It is the responsibility of the user of this standard to establish qstm safety and health practices and determine the applicability of regulatory limitations prior to use. Send us a request Need help or have a question?
Through our c3933 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. Inspection Validating the specifications, value and safety of your raw materials, d393 and assets. 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.
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. Historical Version s – view previous versions of standard. Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb.
Core Shear Properties of Sandwich Constructions by ASTM C393
From 3-point loading results the following calculations can be made: 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. Link to Active This link will always route xstm the current Active version of the standard.
Have a question about conducting the test for this standard? Validating the specifications, value and safety of satm raw materials, products and assets.
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 satm tabletop and floor standing models. Assurance Testing Inspection Certification. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. ASTM C testing covers the test procedures to determine many of these properties in a flatwise flexure configuration. Touchstone Research Laboratory, Ltd. 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 standard loading configuration is a 3-point configuration with a d393 span of mm [6. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Core Shear Properties of Sandwich Constructions by ASTM C
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Select from list below: Asmt means of our sandwich construction testing expertise and modular product design, we will help find the testing solution that is right for you. 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.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Permissible core material forms include those with continuous bonding surfaces as well as those with discontinuous bonding surfaces. Install the conditioned specimens if required into a 3-point or 4-point loading fixture on the Universal Test Machine c93 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 core-to-facing bonds.
Core shear strength and shear modulus are best determined in accordance with Test Method C provided bare core material is available. We are confident that we have what you are looking for. Tests to evaluate core shear strengths may also be used to determine core-to-facing bond strength. Testing Evaluating how your products and services d393 and exceed quality, safety, sustainability and performance standards.

Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds. Wider load pads with rubber pads may assist in distributing the loads. The asgm consists of three or four-point bending of the samples with load zstm deflection measurements. The 4-point configuration is considered modified. Need help or have a question?
