Project Number 21128
Abstract/Scope IEC 61355-1:2008 provides rules and guidelines for the classification of documents based on their characteristic content of information. This second edition cancels and replaces the first edition published in 1997. The main changes with respect to the previous edition are listed below: - Table A.2 has been extended under code P; - Table B.1 in the first edition has been omitted from this second edition; it is being replaced by a separate standard in database format IEC 61355 DB.
