The test described in ISO This method relies upon the detection of E. Bulgarian Institute for Standardization Standards — always a step ahead.
Measurement uncertainties must be calculated and reported as complete standard uncertainties, or as expanded standard uncertainties with an expansion factor of 1. Limit of detection is either three times iwo standard deviation within a batch of a natural sample containing a low concentration of the parameter, or five times the standard deviation of a blank sample within a batch.
Your basket is empty. Under reference BS EN Most probable number method ISO Search all products by. For each parameter in Table 3, the method of analysis used must be capable of measuring activity concentrations with at least the limit of detection specified for that parameter in the second column of that table.
However it must not be used for the enumeration of coliform bacteria in marine water.
