Laboratory internal performance data examples

Examples for the estimation of laboratory internal performance data ENV-ISO 13530 (ISO/TR, 2003) can be applied to ascertain the laboratory internal values for precision, trueness and LOD aceording to the EU directive 98/83/EC. The examples in Table 1.4 m give an indication for the internal actions to be applied by the laboratory. 

By using the combination of specific method accreditation and generic accreditation it will be possible for laboratories to be accredited for all the analyses of which they are capable and competent to undertake. Method performance validation data demonstrating that the method was fit-for-purpose shall be demonstrated before the test result is released and method performance shall be monitored by on-going quality-control techniques where applicable. It will be necessary for laboratories to be able to demonstrate quality-control procedures to ensure compliance with the EN 45001 Standard,3 an example of which would be compliance with the ISO/AOAC/IUPAC Guidelines on Internal Quality Control in Analytical Chemistry Laboratories.12...
