<p><span lang="EN-GB">This document specifies methods for determining the compressive strength, the corresponding compressive strain, the compressive stress at 10 % nominal compressive strain, and the compressive modulus of rigid cellular plastics.</span></p>
<p><span lang="EN-GB">Two procedures are specified. Procedure A and Procedure B.</span></p>
<p><span lang="EN-GB">Procedure A utilizes the compression plate displacement for the nominal property determination. It is used to determine:</span></p>
<ul>
<li><span lang="EN-GB">compressive strength and the corresponding nominal compressive strain;</span></li>

<li><span lang="EN-GB">nominal compressive modulus.</span></li>
</ul>
<p><span lang="EN-GB">Procedure B uses an extensometer and determines the conventional properties. It is used to determine:</span></p>
<ul>
<li><span lang="EN-GB">compressive strength and the corresponding compressive strain;</span></li>
