Corrosion of metals and alloys. Classification of low corrosivity of indoor atmospheres - Determination and estimation of indoor corrosivity Ingestion-build-84997 implementing BS EN 4640-003 best1 Scope This document establishes a classification of low corrosivity of indoor atmospheres. It specifies the reference metals for which a corrosion attack after a defined exposure period is used for determining corrosivity categories of indoor atmospheres of low corrosivity. It defines corrosivity categories of indoor atmospheres according to corrosion attack on standard specimens. It indicates important parameters of indoor atmospheres that can
