Abstract

Abstract:

This paper studies the scatter factor of calendar life, and through research on the distribution regularities of the test data of metallic corrosion, a calculation model of scatter factor which is in consistence of the regularities is determined. Standard deviation is calculated through the corrosion test data. Scatter factor value used in corrosion test is calculated by the given standard deviation.

Key words: metallic corrosion, calendar life, standard deviation, scatter factor, corrosion test

CLC Number:
