This part of ISO 11844 deals with the classification of low corrosivity of indoor atmospheres.
The aim of this part of ISO 11844 is
to characterise indoor atmospheric environments of low 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 low 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.
