Ken et al The information is also available from Schaffner by following the links in the Colloquium Details sheet attached. I'm sure the minutes will be posted on the NPL site afterwards for those of us outside the UK or that don't like meetings on a Friday! http://www.npl.co.uk/electromagnetic/rfmff/tech-transfer/freemet/
