This document gives guidelines for the corrosion testing of metals and alloys exposed in deep-sea 
water, including the selection of the test site, components and assembly of the test system, specimen 
preparation, testing procedure, evaluation after the retrieval from exposure sites and test report.
This document is applicable to the general corrosion exposure testing of metals and alloys as well as 
localized corrosion tests such as stress corrosion cracking (SCC) testing, galvanic corrosion testing and 
crevice corrosion testing of specimens exposed in deep-sea water.
Testing with exposure in deep sea of other materials such as composites and elastomers can also be 
carried out with reference to these guidelines, but the evaluation of these materials after the retrieval 
is different from that of metals and alloys.
This document does not include the performance testing of sacrificial anodes for cathodic protection in 
the field of deep sea, which can be conducted using specified testing cells and equipment in the deep-
sea exposure. However, this guidance can also provide useful information as reference for conducting 
performance testing of sacrificial anodes in deep-sea water.st edition 2020-11 Corrosion of metals and alloys — Guidelines for the corrosion testing of metals and alloys exposed in deep- sea water Corrosion des métaux et alliages — Lignes directrices pour les essais de corrosion des métaux et alliages exposés en eau profonde Reference number ISO 23226:2020(E) ？ ISO 2020 ISO 23226:2020(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 標(biāo)準(zhǔn)截圖
