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 measurementThis 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
