Corrosion de métaux et alliages - Lignes directrices pour l'exposition et l'évaluation des métaux et alliages à la surface de l'eau de mer (ISO 11306:1998)

1.1 La présente Norme internationale donne des indications relatives aux conditions et aux modes opératoires à suivre lors d'essais d'exposition des métaux et alliages à la surface de l'eau de mer afin d'obtenir des résultats comparables quelque soit l'endroit. La présente Norme internationale est applicable aux zones d'exposition allant d'au-dessus du niveau de la mer qui sont mouillées pendant une période significative (zones d'éclaboussement et qui relèvent de la marée) jusqu'à une profondeur à laquelle la composition de l'eau de mer est similaire à celle en surface.

The work ofpreparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for whicha technical committee has been established has the right to be representedon that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISOcollaborates closely with the International Electrotechnical Commission(IEC) on all matters of electrotechnical standardization.Draft International Standards adopted by the technical committees arecirculated to the member bodies for voting. Publication as an InternationalStandard requires approval by at least 75 % of the member bodies castinga vote.International Standard ISO 11306 was prepared by Technical CommitteeISO/TC 156, Corrosion of metals and alloys.SIST EN ISO 11306:1999



INTERNATIONAL STANDARD
© ISOISO 11306:1998(E)1Corrosion of metals and alloys — Guidelines for exposingand evaluating metals and alloys in surface sea water1
Scope1.1
This International Standard gives guidance on the conditions and procedures to be followed when conductingexposures of metals and alloys to surface sea water such that meaningful comparisons may be made for differentlocations. This International Standard applies to exposure areas from above water level which are wet for asignificant period (splash and tidal zones) down to a depth at which the composition of the sea water is similar tothat at the surface.1.2
This practice gives guidance on procedures for the evaluation of the effects of sea water on metals and alloys.1.3
Because of the variability and complexity of sea water, exposures over a minimum period of one year areconsidered necessary to minimize the influence of these variable factors.2
Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisions of thisInternational Standard. At the time of publication, the editions indicated were valid. All standards are subject torevision, and parties to agreements based on this International Standard are encouraged to investigate thepossibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintainregisters of currently valid International Standards.ISO 8407:1991, Corrosion of metals and alloys — Removal of corrosion products from corrosion test specimens.ISO 11463:1995, Corrosion of metals and alloys — Evaluation of pitting corrosion.3
Control specimensIt is prudent, because of the inherent variability in processing conditions, that control specimens be used incorrosion tests. Two kinds of control specimens are needed as follows.A specimen for which performance is well established in the given environment and which actually does corrode (forexample, mild steel). Its corrosion rate will help to determine the length of the test period.A specimen that is known to be normally resistant in the given environment (for example, copper). The purpose ofthis specimen is to make sure that no unusual conditions, such as chemical pollution, were
