Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb — stabilized or unstabilized. ASTM C is a test method for determining the flatwise compressive strength and modulus of honeycomb also known as sandwich core materials.
The force is transmitted to the core sandwich using loading platens.
ASTM C/CMa – Standard Test Method for Flatwise Compressive Properties of Sandwich Cores
Five specimens tested at thickness. 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 and to compute the effective modulus of the core.
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. Need more than one copy? We have no amendments or corrections for this standard. From flatwise compression results the following calculations can be made: Standards can be obtained from appropriate standard authorities.

Combining values from the two systems may result in non-conformance with the standard.
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. The test procedures pertain to compression in this direction in particular, but also can be applied with possible minor aastm to determining compressive properties in other directions.
