This Technical Report is a guideline to carry out the statistical evaluation of data from an inter laboratory test for method validation.<\/p>\n

Its purpose is to detail the methodology of ISO 5725-1:1994, ISO 5725-2:1994 and ISO 5725-3:1994 for the treatment of the data collected under the conditions used within the ECISS\/TC 102 working groups.<\/p>\n
