This document defines moisture damage and it specifies the moisture sources and the moisture transport mechanisms in buildings.

It includes a method for classification of moisture damage based on the relation of:

  • materials and constituent materials,

  • phenomena, and

  • functionalities that can be affected.

This document deals with:

  1. building damage that is induced by (gaseous/liquid/solid) water, and

  2. damage to building components, human health, and property contained in the enclosure. This document makes no mention of warranties for building damage.
