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

Introduction

Corrosion of metals is influenced by factors which can vary significantly with environmental conditions.

Therefore, corrosion resistance determined for metals during alternate immersion testing as described

in this document can vary greatly with the test solution selected, the temperature during immersion

and the temperature and humidity during the drying periods of the test.

Consequently, the result of an alternate immersion corrosion test is not taken as an indication of the

corrosion resistance of the metal tested in all the different service environments where the metal can

be used.

Nevertheless, results obtained by the method described in this document can indicate the relative

corrosion resistance of different metals under in-service conditions, in particular when the service

environment is similar to the test solution selected. The method can also be used to test metals under

an applied tensile stress.

INTERNATIONAL STANDARD ISO 11130:2017(E)
Corrosion of metals and alloys — Alternate immersion test
in salt solution
1 Scope

This document specifies a method for assessing the corrosion resistance of metals by an alternate

immersion test in salt solution, with or without applied stress.

The test is particularly suitable for quality control during the manufacture of metals including

aluminium alloys and ferrous materials, and also for assessment purposes during alloy development.

Depending upon the chemical composition of the test solution, the test can be used to simulate the

corrosive effects of marine splash zones, de-icing fluids and acid salt environments.

The term “metal” as used in this document includes metallic materials with or without corrosion

protection.
This document is applicable to
— metals and their alloys,
— certain metallic coatings (anodic and cathodic with respect to the substrate),
— certain conversion coatings,
— certain anodic oxide coating, and
— organic coatings on metals.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 8044 apply.

4 Principle

The test consists of the immersion of a test specimen, stressed in accordance with ISO 7539-1 or

unstressed, in a salt solution, followed by withdrawal and a period of drying.

The immersion and drying cycle is repeated at a given frequency for a given period. The extent of

attack is then evaluated. For many materials, this provides a more severe corrosion test than simple

continuous immersion.

5 Test solution
5.1 General

During the analysis, unless otherwise stated, use only reagents of recognized analytical grade and

distilled or deionized water or water of equivalent purity.

The test solution shall be prepared in accordance with the prescribed specification. Otherwise, the

solution used should be the one most appropriate to the intended service conditions. Details of a neutral

salt solution that is suitable for simulating the corrosive effect of a marine environment are given in 5.2.

Details of three other test solutions suitable for simulating salt-based de-icing liquid, acid salt conditions

and ocean water are given in Annex A.
5.2 Preparation

The neutral salt solution is prepared by dissolving a sufficient mass of sodium chloride in water to give

a concentration of 35 g/l ± 1 g/l. The water used shall have a conductivity not higher than 2 mS/m

(equal to 20 µS/cm) at 25 °C ± 2 °C.

The sodium chloride shall contain a mass fraction of the heavy metals of copper (Cu), nickel (Ni) and

lead (Pb) in total less than 0,005 %. It shall not contain a mass fraction of sodium iodide more than

0,1 % and a mass fraction of total impurities more than 0,5 %, calculated for dry salt. Sodium chloride

with anti-caking agents should not be used, because such agents may act as corrosion inhibitors or

accelerators.

NOTE A useful sodium chloride salt grade is a grade named Ph. Eur/USP or JIS, ACS.

Prior to use, check the pH of the salt solution using electrometric measurement. Measurements of pH

shall be done using electrodes suitable for measuring pH in weakly buffered sodium chloride solutions

in deionized water. Make any necessary corrections by adding hydrochloric acid, sodium

...
