1 scope
This International Standard provides rules for the structuring of technical information anddocumentation，based on the use of a main document (leading document) for the keepingtogether of information for each object.
NOTE For the definition of a main document,see
3.3.1.2Normative references
The following normative documents contain provisions which，through reference in this text,constitute provisions of this International ‘Standard.
