By way of example, a possible standard for these gauges is given in Annex B. In order to facilitate production, it may be necessary to use gauges having dimensions differi

32、ve) Derived standards Clauses 1 to 3 of this part of IEC 62317 establish the values for the principal dimensions of core assemblies and coil formers and enable full interchangeability for components complying with this primary standard to be achieved. Parties interested in making or using EER-cores
33、may find it desirable to lay down local standards for everyday use, which show the dimensions and tolerances in greater detail than Clause 3, and which correspond to the state of the art in that area. These specifications are known as “derived standards”. When doing so, care should be taken not to e
34、xclude any other type of EER-core meeting this part of IEC 62317, which would also satisfy the performance specification valid for a specific case. It should be noted that even if a component complies with a derived standard and with the requirements of Clause 3 of this primary standard, therefore p
35、ermitting core assemblies and coil formers to be freely interchanged, its constituent parts may not necessarily be interchangeable. When requirements lead to the establishment of a national standard, the relevant national standardization body is strongly requested to insert a note in such a national
36、 standard stating that: a) it is in accordance with the dimensional requirement of this part of IEC 62317 but that more details are given in order to promote its practical use; b) other solutions are possible within the framework of this part of IEC 62317 and should not be excluded if the resulting
37、core and coil formers are functionally interchangeable with those of the national standard. 9 EN 62317-7:2005 Annex B (normative) Example of a standard for gauges to check the dimensions of EER-cores meeting this primary standard B.1 General The gauges shall be in accordance with Table B.1 and its a
