摘要：The 11348-3:2007 ISO method allows the evaluationof the inhibitory effect of water samples on the light emission ofVibrio fischeri; it is essential to quantify the measurement uncertainty, but there is no available guideline. The aim is to come up with a practical approach to calculate the measurement uncertainty. We propose a test with different 3,5-dichlorophenol dilutions to evaluate if the luminometer is functioning properly and, after, we suggest to consider the uncertainty contributions sum (xi), to calculate the standard deviation of reproducibility (SR) and, finally, to express the expanded uncertainty with the formula U = 2SR+ u(xi).
