Corrosion tests in artificial atmosphere at very low concentrations of polluting gas(es) (ISO/DIS 10062:2022)

ISO 10062:2006 specifies tests which are intended to determine the influence of one or more flowing polluting gas(es) at volume fractions less than or equal to 0,000001 on test samples and/or articles of metals and alloys with or without corrosion protection under determined conditions of temperature and relative humidity.
These tests apply to metals and their alloys, metallic coatings (anodic and cathodic), metals with conversion coatings, metals with anodic oxide coatings, and metals with organic coatings.

Essais de corrosion en atmosphère artificielle à très faible concentration en gaz polluants (ISO/DIS 10062:2022)

L'ISO 10062:2006 spécifie des essais ayant pour but de déterminer les effets d'un balayage par un ou plusieurs gaz polluants, à des fractions volumiques inférieures ou égales à 0,000001 sur des éprouvettes et/ou des objets en matériaux métalliques et alliages avec ou sans protection contre la corrosion dans des conditions déterminées de température et d'humidité relative.
Ces essais s'appliquent aux métaux et à leurs alliages, aux revêtements métalliques (anodiques et cathodiques), aux métaux avec des couches de conversion, aux métaux avec des revêtements d'oxyde anodiques et aux métaux avec des revêtements organiques.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

www.iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 156, Corrosion of metals and alloys.

This third edition cancels and replaces the second edition (ISO 10062:2006), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— simplified method has been deleted due to safety issues for operator;
— warnings about each gas have been added in 5.1.2:
— installation environment has been added in Annex A.

Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction

Products with, for example, sensitive electrical functions, may, during storage or operation in indoor

locations, be affected by atmospheric corrosion dependent on climatic factors such as temperature,

relative humidity, air velocity and rate of change caused by temperature and humidity. Additionally,

gaseous pollutants may seriously affect the rate of corrosion, as well as the occurrence of different

corrosion mechanisms. Contaminants on the surface, such as salt, dust, oil and compounds liberated

from plastics, may also affect the rate and mechanism of corrosion.

Different corrosion-promoting gaseous pollutants dominate in different field environments:

— sulfur dioxide and nitrogen oxides in atmospheres influenced by combustion of fossil fuels and in

traffic environments,

— hydrogen sulfide in atmospheres in the vicinity of petrochemical and steel industry, decaying

organic matter, stagnant waters and animal shelters, and

— hydrogen sulfide and chlorine compounds in the vicinity of pulp and paper industry; if chlorine is

used for bleaching

Those gaseous pollutants are known to act as single corrosion-promoting factors. However, in

atmospheres where more than one gaseous pollutant is present, synergistic effects may be initiated.

As a result, a considerable increase in the corrosion rate may occur, compared to the case when the

different gaseous pollutants act as single corrosion-promoting factors.
This document is intended to

a) define a general method using atmospheres polluted by one or more gases at very low volume

fractions ≤ 10 under specified conditions of temperature and relative humidity, so as to avoid

condensation phenomena during the test,

b) define the test apparatus and procedure required to achieve the best possible reproducibility,

c) assess performance under test conditions which accelerate corrosion; as knowledge of operating

conditions proceeds, more suitable pollutants or pollutant mixtures could be used.

4 Apparatus

WARNING — Safety rules for personnel: Handling of the gases used for testing can be hazardous

and must be done by skilled personnel trained to handle such gases. The test equipment must be

used and maintained by skilled personnel, not only so that the tests can be performed correctly,

but also because of the hazards to health and safety that are involved.

Special attention shall be paid to equipment design and the choice of construction materials, in order

that the conditions (less than ± 1 °C for temperature and less than ± 3 % for relative humidity) are

uniformly consistent throughout the working space, able to ensure no condensation in the test chamber,

and are repeatable.

The apparatus shall enable the use, singly or in mixtures, of polluting gas(es) such as SO , H S, Cl and

2 2 2
NO up to at least the concentration required, for each gas, by the test method.
The important parameters are
a) the materials used for the test chamber and the gas handling system,
b) the geometry of the test chamber,
c) the rate and pattern of the gas flow,
d) the homogeneity of gas mixing,
e) the incident illumination (see A.1.6)

The apparatus shall be constructed according to Annex A and shall meet its requirements.

A typical apparatus for polluting-gas corrosion tests is also shown in Annex B.
5 Test methods
5.1 Test severity
5.1.1 General
The test severity, to be given in the relevant specification, is defined by
— the type, concentration and flow rate of polluting gas,
— the temperature,
— the relative humidity, and
— the test duration.
5.1.2 Suggested test methods

The method to be used depends upon the purposes of the test, the nature of the metals and alloys and

the type of protection to be tested.

WARNING — Sulfur dioxide (SO , CAS no. 7446-09-5) is toxic, corrosive and irritating. Refer to

Safety Data Sheet for details. Handling of sulfur dioxide shall be restricted to skilled personnel

or conducted under their control. The apparatus shall be used and maintained by skilled

personnel, not only so that the procedures can be performed correctly, but also because of the

hazards to health and safety that are involved.

WARNING — Hydrogen sulfide (H S, CAS no. 7783-06-4) is flammable gas, toxic, corrosive,

irritating and very toxic to aquatic life. Refer to Safety Data Sheet for details. Handling of
