Corrosion of metals and alloys - Alternate immersion test in salt solution (ISO 11130:2010)
This International Standard 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 International Standard includes metallic materials with or without corrosion protection. The alternate immersion test applies 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. This International Standard is not applicable to stainless steel.
Korrosion von Metallen und Legierungen - Wechseltauchprüfung in Salzlösung (ISO 11130:2010)
Diese Internationalen Norm legt ein Verfahren zur Beurteilung der Korrosionsbeständigkeit von Metallen mit
Hilfe einer Wechseltauchprüfung in Salzlösung, mit oder ohne mechanischer Beanspruchung fest.
Die Prüfung ist besonders als Prüfung zur Qualitätssteuerung bei der Herstellung von Metallen (einschließlich
Aluminiumlegierungen und Eisenwerkstoffen) sowie bei der Entwicklung von Legierungen für Bewertungszwecke
geeignet.
In Abhängigkeit von der chemischen Zusammensetzung der Prüflösung kann die Prüfung angewendet
werden, um die Korrosionswirkung von Meerwasser in der Spritzwasserzone, von Enteisungsflüssigkeiten
sowie von einer säure- und salzhaltigen Umgebung zu simulieren.
Die Benennung „Metall“ im Sinne dieser Internationalen Norm schließt metallische Werkstoffe sowohl mit als
auch ohne Korrosionsschutz ein.
Die Wechseltauchprüfung gilt für:
⎯ Metalle und deren Legierungen,
⎯ bestimmte metallische Überzüge (anodisch und kathodisch bezogen auf den Grundwerkstoff),
⎯ bestimmte Umwandlungsüberzüge,
⎯ bestimmte anodische Oxidüberzüge, und
⎯ organische Überzüge auf Metallen.
Diese Internationale Norm ist nicht anwendbar für rostfreien Stahl.
Corrosion des métaux et alliages - Essai en immersions alternées en solution saline (ISO 11130:2010)
L'ISO 11130:2010 spécifie une méthode permettant d'évaluer la résistance à la corrosion des métaux par un essai en immersions alternées en solution saline, avec ou sans application d'une contrainte.
Cet essai est particulièrement adapté comme essai de contrôle qualité effectué au cours de la production des métaux, y compris les alliages d'aluminium et les matériaux ferreux, ainsi que pour des besoins d'évaluation durant la mise au point d'alliages.
Selon la composition chimique de la solution d'essai, cet essai peut être utilisé pour simuler les effets corrosifs des projections d'eau de mer, des sels de déverglaçage ou des environnements salins acides.
Dans l'ISO 11130:2010, le terme «métal» est utilisé pour désigner tous les matériaux métalliques avec ou sans protection contre la corrosion.
L'essai en immersions alternées s'applique
aux métaux et à leurs alliages,
à certains revêtements métalliques (anodiques ou cathodiques par rapport au substrat),
à certaines couches de conversion,
à certains revêtements formés par oxydation anodique, et
aux revêtements organiques sur métaux.
L'ISO 11130:2010 n'est pas applicable aux aciers inoxydables.
Korozija kovin in zlitin - Preskus z izmeničnim potapljanjem v raztopinah soli (ISO 11130:2010)
Ta mednarodni standard določa metodo za ocenjevanje korozijske odpornosti kovin s preskusom z izmeničnim potapljanjem v raztopinah soli, z uporabo obremenitve ali brez. Preskus je primeren predvsem za nadzor kakovosti med proizvodnjo kovin, vključno z aluminijevimi zlitinami in železnimi materiali, in tudi za ocenjevanje med razvijanjem zlitine. Odvisno od kemične sestave preskusne raztopine se preskus lahko uporablja za simulacijo jedkih učinkov območij pljuskanja morja, tekočin za odtajanje in okoljih s kislimi solmi. Izraz »kovina«, kot se uporablja v tem mednarodnem standardu, vključuje kovinske materiale z zaščito proti koroziji ali brez. Preskus z izmeničnim potapljanjem se uporablja pri – kovinah in njihovih zlitinah, - določenih kovinskih prevlekah (anodnih in katodnih glede na substrat), - določenih pretvorbenih prevlekah, - določenih anodnih oksidnih prevlekah, in – organskih prevlekah na kovinah. Ta mednarodni standard ne velja za nerjavno jeklo.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 11130 was prepared by Technical Committee ISO/TC 156, Corrosion of metals and alloys.

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
International Standard 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 International Standard 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.

3 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/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.
4 Test solution
4.1 General.
During the analysis, unless otherwise stated, use only reagents of recognized analytical grade and distilled or
demineralized 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. Subclause 4.2 gives details of a
neutral salt solution that is suitable for simulating the corrosive effect of a marine environment.
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.
4.2 Preparation.
The neutral salt solution is prepared by dissolving a sufficient mass of sodium chloride in water to give a
−1 −1 −1
concentration of 35 g⋅L ± 1 g⋅L . The water used shall have a conductivity not higher than 2 mS⋅m (equal
−1
to 20 µS⋅cm ) at 25 °C ± 2 °C.
The maximum allowable impurity content in the sodium chloride solution shall be as given in Table 1:

Prior to use, check the pH of the salt solution using electrometric measurement at 25 °C ± 2 °C or in routine
checks, with a short-range pH paper which can be read in increments of 0,3 pH units or less. If the pH value
determined is outside the range of 6,0 to 7,0, adjustments shall be made by adding dilute hydrochloric acid or
sodium hydroxide to the salt solution.

The volume of the test solution should be defined by the product specification. If no specification is available, it
is recommended that the volume should be not less than 3 L per decimetre square of test specimen area.
5 Apparatus
5.1 General.
The apparatus shall include the following components.
⎯ A suitable system designed for the automatic, continuous performance of complete cycles of alternate
immersion and withdrawal of the test specimens. This system shall provide uninterrupted operation
throughout the duration of the test (see 6.1). Each test specimen shall be connected to the system using
suitable insulating material.
⎯ One or more glass or plastic containers for the reagent. Only one kind of metal, alloy or coating should be
immersed in each container. Replicate specimens can share the same container.
The system should be designed such that the time taken for full immersion or withdrawal of each specimen is
not more than 2 min.
NOTE Suitable apparatus for conducting alternate immersion tests in salt solution is illustrated schematically in
Annex B.
