This document establishes the measurement of specific heat capacity cp using temperature modulated differential scanning calorimetry such as description of the principle and the apparatus, sampling, calibration and general aspects of the procedure and test report as below.

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).
