Standard Test Method for Edgewise Compressive Strength of Sandwich Constructions.
The standard determines the compression properties of the sandwich structural construction in a direction parallel to the sandwich cladding plane. Permitted core material shapes include those with continuous bonding surfaces as well as those with discontinuous bonding surfaces. This test method consists of subjecting a sandwich panel to a compressive force increasing monotonically parallel to the plane of its faces. The force is transmitted to the panel through fixed or joined end brackets. Stress and strength are reported in terms of the nominal cross-sectional area of the two face sheets, instead of the total thickness of the sandwich panel, although alternative stress calculations can optionally be specified.
