This European Standard specifies the equipment and procedures for determining the long-term water absorption of test specimens. It is applicable to thermal insulating products.<\/p>\n
This European Standard specifies two options:<\/p>\n
Method 1 – partial immersion<\/p>\n<\/li>\n
Method 2 – total immersion<\/p>\n<\/li>\n<\/ul>\n
The long-term water absorption by partial immersion is intended to simulate the water absorption caused by long term water exposure.<\/p>\n
The long-term water absorption by total immersion is not directly related to the conditions on site, but has been recognised as a relevant condition of test for some products in some applications.<\/p>\n
