Diagnosing moisture damage in buildings and implementing countermeasures — Part 2: Assessment of conditions

This document describes methods for diagnosing and assessing conditions that can result in moisture damage impacting the building’s energy and durability performance. For the purpose of classifying moisture damage, methods in this document range from basic observation techniques to more complex methods using equipment to more accurately or precisely render a condition assessment and provide data. This document does not ensure that the methods identified will result in the full disclosure of all moisture damage conditions.

Diagnostic des dommages causés par l’humidité dans les bâtiments et mise en œuvre de solutions de remédiation — Partie 2: Évaluation des conditions

Le présent document décrit les méthodes de diagnostic et d’évaluation des conditions susceptibles d’entraîner des dommages causés par l’humidité et d’avoir un impact sur les performances énergétiques et la durabilité du bâtiment. Aux fins de la classification des dommages causés par l’humidité, les méthodes présentées dans le présent document vont des techniques d’observation de base à des méthodes plus complexes faisant appel à des équipements permettant de procéder à une évaluation plus exacte ou plus fidèle des conditions et de fournir des données. Le présent document n’assure pas que les méthodes identifiées aboutissent à la mise en évidence complète de tous les dommages causés par l’humidité.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
The term “moisture damage” is interpreted in many ways. Cognisance of moisture damage is not always
consistent between specialists (e.g. engineers, researchers), residents and building users, leading to
confusion. For example, residents and building users would consider the occurrence of condensation on
window glass or on the surface of a metal sash to be a prime example of moisture damage, but considering
the durability of glass and metal materials, it is not always appropriate to call that “moisture damage.”
However, supposing the condensation that occurs on the glass becomes the cause of an outbreak of mould
on the curtains, thatit would be called moisture damage. It is imperative to resolve the confusion by
defining “moisture damage” and by demonstrating the criteria for diagnosing whether an occurring
[1] [1]
phenomenon in a building is moisture damage or not .
This document defines moisture damage in buildings and demonstrates criteria for diagnosing whether
a phenomenon that occurs in a building is moisture damage or not, for a common understanding between
residents, building users and specialists. It also demonstrates methods for the classification of moisture
damage.
