They are common to various types of mechanica
22、l structures, but most of them are derived from IEC Publications 297-1, 297-2 and 297-3. Illustrations are added in the list of terms when appropriate to support correct term usage. Where a term is self-explanatory no definition is given, for instance “front panel”. The same applies for terms alread
23、y defined in IEC Publication 50. 2 Object The terms in this standard shall be used in other standards for mechanical structures of electronic equipment and in related technical documents. The purpose is to promote a clear understanding of the subject characterized by a standard term and thereby to e
24、ase verbal and written communications. For example, the term “equipment practice” shall be used when a mechanical structure is meant according to the definition contained in the list given in this standard. 3. Terminologie et dfinitions3.
