All laboratories are visited every year and re-assessed at four-yearly intervals – and the latest situation is revealed in this edition.
Laboratories with a NAMAS stamp meet ISO 9000 series standards, including those of the model described in 9002 when they are acting as suppliers producing calibration or test results.
The book is divided into testing and measurement sections. Calibration fields include electrical measurements, dimensional, fluids, temperature, radiological, analysis, hardness, acoustical, humidity, force, flux, fibre optic, mass and pressure.
