Test Piece Measurement 1. Introduction Metrology is the science of measurement. It covers both the theoretical and the practical issues related to measurement. The aim of measurement is to determine the value of a quantity, for instance length, temperature, time, electrical resistance or the amount of substance of a certain material. The word metrology is derived from the Greek word `μετρον', `metron': to measure. It was originally used to describe precise measurement of linear dimensions of an object and many of the earlier (post- war) engineering textbooks make extensive use of the term. It is therefore hardly surprising that the SI unit of length, the metre, is also derived from the same Greek word `metron'. During the late fifties and
