The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent ISO22309waspreparedbyTechnicalCommitteeISO/TC202,Microbeamanalysis. This second edition cancels and replaces the first edition (IsO 22309:2006), of which it constitutes a minor revision. The main changes are as follows: the title has been modified to make it quite clear that the method is not suitable for light elements with an atomic number of less than 11; Subclause 6.2 has been modified to take into account the use of silicon drift detectors iv @ ISO 2011 All rights reserved BS ISO 22309:2011 ISO22309:2011(E) Introduction which are
