(Main)Corrosion of metals and alloys - Accelerated cyclic test with exposure to acidified salt spray, dry and wet conditions (ISO 16151:2018)
Corrosion of metals and alloys - Accelerated cyclic test with exposure to acidified salt spray, dry and wet conditions (ISO 16151:2018)
This document specifies two accelerated corrosion-test procedures, Methods A and B, for the comparative evaluation of metallic materials with or without permanent corrosion protection or temporary corrosion protection in outdoor salt and/or acid rain environments. It also specifies the apparatus used. The two tests involve cyclic exposure of the specimens to acidified salt spray, "dry" and "wet" conditions.
The particular advantages of the two tests over conventional accelerated tests, such as the neutral salt spray (NSS) test as specified in ISO 9227 lie in their better ability to reproduce the corrosion that occurs in outdoor salt and/or acid rain environments. They are also useful for evaluating cosmetic corrosion.
Method A is applicable to
— metals and their alloys,
— metallic coatings (cathodic),
— anodic oxide coatings, and
— organic coatings on metallic materials.
Method B is applicable to
— steel coated with anodic coatings, and
— steel coated with anodic coatings covered with conversion coatings.
Korrosion von Metallen und Legierungen - Schnellprüfungen unter zyklisch wechselnder Beanspruchung mit saurem Salzsprühnebel, trockenen und feuchte Bedingungen (ISO 16151:2018)
Corrosion des métaux et alliages - Essais cycliques accélérés avec exposition au brouillard salin acidifié, en conditions «sèches» et en conditions «humides» (ISO 16151:2018)
Le présent document spécifie deux modes opératoires d'essai de corrosion accélérés, à savoir les méthodes A et B, pour l'évaluation comparative de matériaux métalliques, revêtus ou non d'une protection permanente ou temporaire contre la corrosion dans des environnements extérieurs salins et/ou de pluie acide. Il spécifie également l'appareillage utilisé. Les deux essais impliquent une exposition cyclique des éprouvettes à un brouillard salin acidifié, dans des conditions «sèches» et «humides».
Par rapport aux essais accélérés traditionnels, tels que l'essai au brouillard salin neutre (NSS) spécifié dans l'ISO 9227, l'intérêt des deux essais réside tout particulièrement dans leur meilleure aptitude à reproduire la corrosion qui se produit dans des environnements extérieurs salins et/ou de pluie acide. Ils sont également utiles pour évaluer la corrosion cosmétique.
La méthode A s'applique
— aux métaux et à leurs alliages,
— aux revêtements métalliques (cathodiques),
— aux revêtements d'oxydes anodiques et
— aux revêtements organiques sur matériaux métalliques.
La méthode B s'applique à
— l'acier présentant des revêtements anodiques, et
— l'acier présentant des revêtements anodiques recouverts de couches de conversion.
Korozija kovin in zlitin - Pospešeni (stopnjevani) ciklični preskus z izpostavljanjem kislo-slanemu pršenju v suhih in vlažnih pogojih (ISO 16151:2018)
Ta dokument določa metodi pospešenega preskušanja korozije (A in B) za primerjalno vrednotenje kovinskih materialov s trajno zaščito pred korozijo ali brez nje ali z začasno zaščito pred korozijo v zunanjem slanem in/ali kislem okolju. Določa tudi uporabljeno napravo. Preskusa vključujeta ciklično izpostavljenost vzorcev kislo-slanemu pršenju v »suhih« in
»vlažnih« pogojih.
Posebne prednosti preskusov v primerjavi z običajnimi pospešenimi preskusi, kot je preskus z nevtralno slano meglico (NSS), opredeljen v standardu ISO 9227, so v njuni boljši sposobnosti reprodukcije korozije, ki se pojavi v zunanjem slanem in/ali kislem okolju. Uporabljata se tudi za vrednotenje kozmetične korozije. Metoda A se uporablja za:
– kovine in njihove zlitine,
– kovinske prevleke (katodne),
– anodno oksidne prevleke in
– organske prevleke na kovinskih materialih.
Metoda B se uporablja za:
– jeklo, prevlečeno z anodno prevleko in
– jeklo, prevlečeno z anodno prevleko, prekrito s konverzijskim premazom.

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
