The work detailed in this report has been undertaken as part of a
research project supported by the Machine Tool Industry Research Association
on Ergonomics and Machine Tool Design. In an early research project report,
some comments were offered on the Draft British Standard for Symbols for
Machine Tool Indicator Plates, and the Director of M.T.I.R.A, invited the
author to elaborate on these preliminary criticisms. Although finalisation
of the British Standard was imminent, it was realised that it would be remiss
if a research project specifically devoted to ergonomics and machine tool
design did not make a detailed and constructive assessment of the proposed
standard symbols
