Corrosion of metals and alloys - Classification of low corrosivity of indoor atmospheres - Part 1 : determination and estimation of indoor corrosivity

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 serve as a basis for an estimation of indoor corrosivity. The selection of a method for the determination of corrosion attack, description of standard specimens, exposure conditions and evaluation are given in ISO 11844-2. The measurement of environmental parameters affecting indoor corrosivity is given in ISO 11844-3.

Corrosion of metals and alloys - Classification of low corrosivity of indoor atmospheres - Part 1 : determination and estimation of indoor corrosivity

<p>ISO11844-1:2006 deals with the classification of low corrosivity of indoor atmospheres.</p> <p>The aim of ISO11844-1:2006 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.</p> <p>ISO11844-1:2006 specifies technical metals, whose corrosion attack after a defined exposure period is used for determination of corrosivity categories of indoor atmospheres of low corrosivity.</p> <p>ISO11844-1:2006 defines corrosivity categories of indoor atmospheres according to corrosion attack on standard specimens.</p> <p>ISO11844-1:2006 indicates important parameters of indoor atmospheres that can serve as a basis for an estimation of indoor corrosivity.</p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
