Corrosion of metals and alloys - Classification of low corrosivity of indoor atmospheres - Part 1: Determination and estimation of indoor corrosivity (ISO 11844-1:2006); German version EN ISO 11844-1:2008
This part of ISO 11844 deals with the classification of Iow corrosivity of indoor atmospheres.
The aim of this part of ISO 11844 is
-- to characterise indoor atmospheric environments of Iow corrosivity that can affect metals and metallic
coatings during storage, transport, installation or operational use,
-- to set a consistent way of indoor corrosivity classification, and
-- to prescribe procedures for derivation and estimation of indoor corrosivity categories.
This part of ISO 11844 specifies technical metals, whose corrosion attack after a defined exposure period is
used for determination of corrosivity categories of indoor atmospheres of Iow corrosivity.
This part of ISO 11844 defines corrosivity categories of indoor atmospheres according to corrosion attack on
standard specimens.
This part of ISO 11844 indicates important parameters of indoor atmospheres that can serve as a basis for an
estimation of indoor corrosivity.
Selection of a method for determination of corrosion attack, description of standard specimens, its exposure
conditions and evaluation are the subject of ISO 11844-2. Measurement of environmental parameters
affecting indoor corrosivity is the subject of ISO 11844-3.
