DIN EN ISO 16535:2017-12

This International Standard specifies the equipment and procedures for determining the long term water absorption of test specimens. It is applicable to thermal insulating products.This International Standard specifies two options:- Method 1 - partial immersion- Method 2 - total immersionThe 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.
