Error and Uncertainty in Metallographic Measurement

Introduction

The idea of using ‘uncertainty’ has been slow to be adopted
in many industries – this is perhaps understandable given
the length of explanation required to cover all aspects of the
general guide (134 pages in the GUM published by the Joint
Committee for Guides in Metrology). However, the reason
for its introduction is to pursue a better understanding of the
causes of differences in measurement, as well as to promote
the consideration of causes of uncertainty. The basic principles
are quite straightforward, and when we apply them to daily
practice in the workplace – as well as, perhaps, to our approach
to development of Standards – we can be better positioned to
understand and control the measurements that we make to
reduce uncertainty and measure more precisely.
