According to conceit of author about classification of error,this paper describes to comprehend the classification of uncertainty in sugges-tion of INC-1 (1980), which suggested by BIPM working group on statmentof uncertainty. And it introduces a method of appraised uncertainty of B class.This paper advances that the unknown error in deterministic function andthe random error which don' t cause randomly fluctuation of measuring datacan deal with uncertainty of B class. Further it considers error function orcurve as a realization of ergodic stationary random process. So we can finethe pseudodistribution density of this error function or curve by analyticmethod or plotting method, which have been given in this paper. As a resultwe can use its pseudo-standard deviation to express uncertainty of B class.Moreover we can fine corresponding pseudo-confidence factor of confidenceinterval while it is neccessary.
