3.1
corrosion
physicochemical interaction between a metallic material and its environment that results in changes in the properties of the metal, and that may lead to significant impairment of the function of the metal, the environment or the technical system, of which these form a part
Note 1 to entry: This interaction is often of an electrochemical nature.
3.2
corrosive agent
substance that will initiate or promote corrosion (3.1) when in contact with a given metal
3.3
corrosive environment
environment that contains one or more corrosive agents (3.2)
3.4
corrosion system
system consisting of one or more metals and those parts of the environment that influence corrosion (3.1)
Note 1 to entry: Parts of the environment may be, for example, coatings, surface layers or additional electrodes (7.1.2).
3.5
corrosion effect
change in any part of the corrosion system (3.4) caused by corrosion (3.1)
3.6
corrosion damage
corrosion effect (3.5) that causes impairment of the function of the metal, the environment or the
technical system, of which these form a part
6 Terms related to corrosion testing
6.1
corrosion test
test carried out to assess the corrosion resistance (3.13) of a metal, the environmental contamination
by corrosion products (3.8), the effectiveness of corrosion protection (5.1) or the corrosivity (3.14) of an
environment
6.2
field corrosion test
corrosion test (6.1) conducted in a natural environment, such as air, water or soil
6.3
service corrosion test
corrosion test (6.1) conducted in service
6.4
simulated corrosion test
corrosion test (6.1) conducted under simulated service conditions
6.5
accelerated corrosion test
corrosion test (6.1) carried out under more severe conditions that will yield results in a shorter time
than in service
6.6
cyclic atmospheric corrosion test
accelerated corrosion test (6.5) by exposure of coated and uncoated specimens to alternating
environmental conditions designed to compare performance in atmospheric exposure
7.4.10 galvanic anode sacrificial anode metallic component used as an anode (7.1.4) for galvanic protection (7.4.4) and cathodic protection (7.4.3) Note 1 to entry: The galvanic anode must have a lower corrosion potential (7.1.20) than the metal that is to be protected.
7.4.11 insoluble anode DEPRECATED: dimensionally stable anode anode (7.1.4) used for cathodic protection (7.4.3) by impressed current protection (7.4.5) where the anode is not significantly consumed EXAMPLE Platinized titanium.BS EN ISO 8044 pdf download.
