Introduction
The definitions in this document strike an appropriate balance between precision and brevity. The main purpose of this document is to provide information that can be used by all interested parties
understood as definitions with the same meaning. Some of the corrosive terms in use today are conventional, but not always logical.
Therefore, it is not possible to define certain terms in the form used in certain countries. Because of the occasional conflict between tradition and logic, some fixed
Righteousness inevitably compromised.
For example, the term "corrosion" is used to refer to the process, the result of the process and the damage caused by the process. In this document, corrosion is understood as excessive
Procedure. Any detectable result of corrosion in any part of a corrosion system is referred to as a "corrosion effect". The term "corrosion damage" covers damage as
Any damage to the function of the system composed of metal and the environment. Therefore, the term "corrosion protection" means that it is important to avoid corrosion damage without
is to prevent corrosion. Because preventing corrosion is impossible in many cases, and sometimes unnecessary.
