This document specifies methods for determining the compressive strength and corresponding relative deformation; the compressive stress at 10 % relative deformation; and the compressive modulus of rigid cellular plastics.

Two methods are given. Procedure A employs crosshead motion for determination of nominal compressive properties. Procedure B employs displacement measuring device (including contact and optical types).
