Scope

This Standard specifies a test method for compressive properties of porous and
cellular metals with a porosity of 50 % or more. Compressive tests can be carried out
at ambient temperature under quasi-static strain rate conditions.

Summary	This Standard applies to a 50% or higher metal honeycomb porous and porosity, measured by the compression test method compressive strength of the first peak, plateau stress, the end point of the platform, absorbing energy, the energy absorption efficiency, quasi-elastic gradient elasticity gradient, the provisions specified compressive strength and compressive stress characteristic values. It is a quasi-static compression test strain test at room temperature.
