---|---|---|---|---|---|---|---|
1 “Limit of detection” means the minimum value of the parameter examined which it is possible to detect. | |||||||
2 “Precision” means the range within which 95% of the results of measurements made on a single sample, using the same method, are located. | |||||||
3 “Accuracy” means the difference between the true value of the parameter examined and the average experimental value obtained. | |||||||
4 If the samples contain so much suspended matter as to require special preliminary treatment, the accuracy values shown in the above Table may as an exception be exceeded and are to be regarded as a target. These samples must be treated so as to ensure that the analysis covers the largest quantity of substances to be measured. | |||||||
