This good practice guide is written for those who need to make dimensional measurements
but are not necessarily trained metrologists. On reading this guide you should have gained a
basic knowledge of fundamental good practice when making dimensional measurements. An
introduction to length units and key issues such as traceability and uncertainty is followed by
some examples of typical sources of error in length measurement. Checking to specification,
accreditation and measurement techniques are also covered along with an introduction to
optical measurement techniques.
