The primary objective of this standard is to address the 'why' and 'how' of performing tribocorrosion tests, as well as the need for a well-described testing concept and protocol for passivating materials. This protocol provides: - A description of the physical, chemical and electrochemical background necessary for the correct application of experimental tools and techniques allowing a qualitative and/or quantitative analysis of tribocorrosion tests. - A way to characterize the impact of tribocorrosion on the reliability and durability of tribological systems, and to prevent and to deal with risks. - A detailed description of a testing protocol for passivating metallic materials that will allow an interlaboratory comparison of experimental data. This includes a detailed description of sample preparation before testing, the selection of appropriate testing conditions, the performance of tests, and the post-testing data handling.
