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.

This document specifies the technical delivery conditions in two test categories for seamless tubes of circular cross section made of austenitic (including creep resisting steel) and austenitic-ferritic stainless steel which are intended for pressure and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures.

NOTE Once this standard is published in the Official Journal of the European Union (OJEU) under Directive 2014/68/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EC is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied will be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent manufacturing processes which may affect properties of the base materials.

ISO 4992-1 specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for general purposes, and the methods for determining internal discontinuities by the pulse-echo technique.

ISO 4992-1 applies to the ultrasonic testing of steel castings which have usually received a grain-refining heat treatment and which have wall thicknesses up to and including 600 mm. For greater wall thicknesses, special agreements apply with respect to the test procedure and the acceptance levels.

This part of ISO 4992 does not apply to austenitic steels and to joint welds.
