This document specifies the apparatus, materials, specimen preparation, procedures, results and reports for comparing the corrosion rates of the steel reinforcement bars in concrete in the simulated marine and coastal environments.

This document is applicable to test the corrosion rates of the ordinary steels as well as the corrosion resistant steels, and give guidelines for material selection in the corrosion design.

This document deals with the classification of low corrosivity of indoor atmospheres.

The aim of this document 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 document 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 document defines corrosivity categories of indoor atmospheres according to corrosion attack on

standard specimens.

This document 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.

This International Standard specifies methods for determination of corrosion rate with standard specimens of metals in indoor atmospheres with low corrosivity. For this direct method of evaluation corrosivity different sensitive methods can be applied using standard specimens of the following metals: copper, silver, zinc steel and lead. The values obtained from the measurements are used as classification criteria for the determination of indoor atmospheric corrosivity.
