Calibration issues for measurement of moisture in materials.

This summary report details practical measurements made at the National Physical Laboratory (NPL) using instrumentation to measure the moisture content of selected materials. The experience gained in this new field of measurement for NPL has enabled measurement issues to be identified and uncertainty budgets to be evaluated for the selected techniques. Approaches to further work are identified which seek to improve traceability for the selected methods of moisture measurement in materials. This work constitutes Deliverable 2 of Project UP10 of the Department of Business Innovation and Skills - National Measurement System Programme for Materials and Thermal Metrology, 2005-2010.
