Full information on the voting for the approval of this amendment can be found in the report
on voting indicated in the above table.
The committee has decided that the contents of the base publication and its amendments will

INTRODUCTION
This amendment introduces corrections which are needed to align with ISO 13584-42 in
order to keep the common ISO 13584-IEC 61360 dictionary schema common across both
committees.
In a number of clauses, where the common EXPRESS model allows more freedom, IEC has
defined more restrictions which are found in the methodology part of IEC 61360-1.

INTRODUCTION
Replace the quotations from IEC 61360-1 and ISO 13584-42 by the following more recent
ones:
“This part of IEC 61360 provides a firm basis for the clear and unambiguous definition of
characteristic properties (data element types) of all elements of electrotechnical systems from
basic components to subassemblies and full systems. Although originally conceived in the
context of providing a basis for the exchange of information on electric/electronic
components, the principles and methods of this standard may be used in areas outside the
original conception such as assemblies of components and electrotechnical systems and
subsystems.”
and
“This part of ISO 13584 provides rules and guidelines for library data suppliers to create
hierarchies of families of parts according to a common methodology intended to enable multi-
supplier consistency. These rules pertain to the following: the method for grouping parts into
families of parts to form a hierarchy; the dictionary elements that describe the families and
properties of parts.”
