3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Corrosion rate
The annual average corrosion depth calculated by metal corrosion weight loss, unit. mm/a.
[GB 50050-2007, definition 2.1.13]
The corrosion rate is defined by formula (1).
X=
8760×10×(m-m0)
s×ρ×t
(1)
Where.
X --- Corrosion rate, in millimeters per year (mm/a);
m ---the mass loss of the test piece, in grams (g);
m0 --- the average mass loss of the test piece in the pickling blank test, in grams (g);
s --- the surface area of the test piece, in square centimeters (cm2);
ρ ---The density of the test piece, in grams per cubic centimeter (g/cm3);
t --- the test time of the test piece, in hours (h);
8760-the number of hours in 365 days per year, in hours per year (h/a);
10 ---The feed rate between centimeters and millimeters, in millimeters per centimeter (mm/cm).
