<p>This document specifies the equipment and procedures for determining the long-term water absorption of test specimens. It is applicable to thermal insulating products.</p>
<p>This document specifies two methods:</p>
<p>— Method 1: Partial immersion;</p>
<p>— Method 2: Total immersion.</p>
<p>The long-term water absorption by partial immersion is intended to simulate the water absorption caused by long-term water exposure.</p>
<p>The long-term water absorption by total immersion is not directly related to the conditions on site, but has been recognized as a relevant condition of test for some products in some applications.</p>
