IEC 81346-1:2009, published jointly by IEC and ISO,establishes general principles for the structuring of systems includingstructuring of the information about systems. Based on these principles, rulesand guidance are given for the formulation of unambiguous referencedesignation
s for objects in any system. The reference designation identifiesobjects for the purpose of creation and retrieval of information about anobject, and where realized about its corresponding component. This editionincludes the following substantial changes with respect to the previous one: - a new introductory clause providing a description and explanation to theconcepts used elsewhere in the publication; - a more comprehensive description of the structuring principles and rules forstructuring are provided; - 'other aspects' are introduced, and the prefix sign # is assigned to theseaspects; - the concept of reference designation group has been deleted; - the specific term 'transition' has been avoided and been replaced by animproved textual description of this phenomenon in annex D; - a new clause about labelling is introduced; - the old annexes have been removed with the exception of the annex showing anexample of the application of reference designations within a system; - a new annex explaining the manipulation of objects is introduced; - 4 new annexes are introduced as rearrangement of detailed examples orexplanatory information.
