This document specifies the equipment and procedures for determining the long-term water absorption of test specimens. It is applicable to thermal insulating products. This document specifies two methods: — Method 1: Partial immersion; — Method 2: Total immersion. The long-term water absorption by partial immersion is intended to simulate the water absorption caused by long-term water exposure. 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.
