Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
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. Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb — stabilized or unstabilized.
If the document is revised or amended, you will be notified by email. Standards Subsctiption may be the perfect solution. Validating the specifications, value and safety of your raw materials, products and assets.
The sandwich core will be subjected to a uniaxial compressive force normal to the plane of the facings as the core will be placed in a structural sandwich construction.
Flatwise Compressive Properties by ASTM C365
Formally confirming that your products and services meet all trusted external and internal standards.
This standard is also available to be included in Standards Subscriptions. 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.
Already Subscribed to this document. Have a question about conducting the c3665 for this standard? 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.
Standards can be obtained f365 appropriate standard authorities. 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. ASTM C testing covers 3c65 determination of compressive strength and modulus of sandwich cores.
Information gained from ASTM C is often applied to design processes, materials specs, research and development, and quality assurance.

ASTM C – 00 Standard Test Method for Flatwise Compressive Properties of Sandwich Cores
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. Historical Version s – view asrm versions of standard.
Continuous bonding surfaces — minimum facing area shall be mm 2 1. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. These mechanical properties can, in turn, be used in design purposes, material specifications, research and development applications and quality assurance.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: By means of our testing expertise and modular product design, we will help find the solution that is right for you. Deformation data can be obtained, and 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 asym to compute the effective modulus of the core.
From flatwise compression results the following calculations can be made: The test procedures pertain to compression in ast direction in particular, but also can be applied with possible minor variations to determining compressive properties in other directions. 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.
Install the conditioned specimens if required into the loading platens on the Universal Test Machine and initiate at a astj grip separation significant enough to produce failure within 3 to 6 minutes.
