3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Corrosion rate The 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= 87600×(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); 87600---constant, the number of hours per year in 365 days is multiplied by the centimeter to convert to millimeters of 10. 3.2 Corrosioninhibitionefficiency The corrosion inhibition percentage is calculated based on the change of the metal corrosion rate with and without corrosion inhibitor (blank). ......
