플라스틱재료의 기계적 특성시험 불확도추정에 대한 고찰

Recently, uncertainty of measurement became a major concern for the people working on the laboratory evaluation and accreditation uncertainty of measurement is a parameter associated with the result of a measurement that characteristics the dispersion of the value that could reasonably be attributed to the measured.' This study analysed how to estimate uncertainty of measurement in mechanical characteristic exam for Plastic material. its uncertainty was estimated according to International Organization for Standardization(ISO), they were named to A type uncertainty. B type uncertainty, combined standard uncertainty, and expanded uncertainty. We obtained that the combined standard uncertainty was 0.96697 ㎫ and the expanded uncertainty was 2.291㎫.
