BS 8496:2007 Water quality - Enumeration of micro-organisms in water samples - Guidance on the estimation of variation of results with particular reference to the contribution of uncertainty of measurement
This British Standard gives guidance on interpretation of the
requirements specified in BS EN ISO/IEC 17025:2005 with regard to
the uncertainty of measurement in microbial counts in water samples. It gives guidance on the estimation of variation in results between
replicate sub-samples, which will include that due to uncertainty of
measurement, in order to assess whether the variation due to uncertainty of measurement has been controlled in accordance with the
requirements specified in BS EN ISO/IEC 17025:2005. It is applicable
to examination of sub-samples as part of a quality assurance system. It is applicable to samples of all types of water.
