Need and Difficulties in Uncertainty of Measurement

摘要

Uncertainty of measurement has attracted more research in recent past. In this paper, an attempt is made to explain the concept and need of measurment uncertainty. The uncertainty of measurement is related to measurement and calibration process only. The uncertainty of measurement(UOM) is applied in various application such as mechanical, chemical, electrical and civil testing equipments. The paper focus on difficulties in estimation of sources of uncertainty and their estimation. The gaps in the research are identified along with the scope of UOM in various application. The effects of qualitative factors can be possible using data collection through questionnaire.
