Abstract
The importance of establishing common measurement standards to support underwater acoustical calibration and testing in the UK, and therefore the need to demonstrate calibration traceability, has progressively grown over the last few years. In the UK, the National Measurement System provides the means of achieving traceability through the establishment and dissemination of primary standards of measurement. This paper will outline the progress made so far in establishing the UK’s underwater acoustical measurement standards, and look forward to plans to extend the capability to cover the whole frequency range of interest, over the ranges of temperature and hydrostatic pressure applicable to simulated ocean conditions. The validation of these measurement standards will also be discussed.
