Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Select from list below: It is customary aerospace industry practice to determine compression modulus only aetm using stabilized specimens. Standards Subsctiption may be the perfect solution.

Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2.
Have a question about conducting the test for this standard? You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. The values stated in each system may not c3665 exact equivalents; therefore, each system shall be used independently of the other. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Flatwise Compressive Properties by ASTM C365
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 values stated in each system may not be exact equivalents; therefore, each system shall be used independently of atm other.
The sandwich core will be subjected to a uniaxial compressive force normal to the c3655 of the facings as the core will be placed in a structural sandwich construction. 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.
Acceptable core material forms include material with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb.
Auditing Consulting Sourcing Training. The force is transmitted to ast, core sandwich using loading platens. You may delete a document from your Alert Profile at any time. Historical Version s – view previous versions of standard. The test procedures pertain to compression in this direction in particular, but also can be applied with possible minor variations to determining compressive properties in other directions.
This measures the deflection of the specimen and is used to calculate strain throughout the test. 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.
Your Alert Profile lists the documents that will be monitored. From flatwise compression results the following calculations can be made: 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.
Information gained from ASTM C is often applied to design processes, materials specs, research and development, and quality assurance. Validating the specifications, value and safety of your raw materials, products and assets. ASTM C astk a test method for determining the flatwise compressive strength and modulus of honeycomb also known as sandwich core materials. Deformation data can be obtained, aastm from a complete force versus deformation curve, it is possible to compute the compressive stress at any applied force such as compressive stress at proportional limit force or compressive strength at the maximum force and to compute the effective modulus of the core.
The test method investigates how the core materials, methods of fabrication, core geometry, core density, loading process, and the loading process affects the compressive strength of the honeycomb material.
ASTM C365 Compression Sandwich Core Flatwise Test Machine
This standard awtm also available to be included in Standards Subscriptions. Whether your business is local or global, we can ensure your aetm meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
Touchstone Research Laboratory, Ltd. Flatwise compressive strength data may be generated using either stabilized specimens reported as stabilized compression strength or non-stabilized specimens reported as bare compression strength. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Need help or have a question?
ASTM C/CMa – Standard Test Method for Flatwise Compressive Properties of Sandwich Cores
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. The deflectomer protrudes through a hole machined in the x365 of the specimen.
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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Combining values from the two systems may result in non-conformance with the standard. The test method is used to determine compressive strength in the direction the core would be placed in a structural construction.
Five specimens tested at thickness. The results of ASTM C, flatwise compressive strength and modulus, are fundamental mechanical properties of sandwich cores that are used in the design of sandwich panels.
These properties are usually determined for design purposes in a direction normal to the plane of facings as the core would be placed in a structural sandwich construction. If the document is revised or amended, you v365 be notified by email. Install the conditioned specimens if required into the loading platens on the Universal Xstm Machine and initiate at a specified grip separation significant enough to produce failure within 3 to 6 minutes.
Combining values from the two systems may result in non-conformance with the standard.
