It is identical with IEC61854:1998. The UK participation in its preparatio

4、related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. From1January1997, all IEC publications have the number60000added to the old number. For instance, IEC27-1 has been renumbe

5、red as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to

6、international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find”

It covers rigid spacers, flexible spacers and spacer dampers. It does not apply to interphase spacers, hoop spacers and bonding spacers. NOTEThis standar

31、d is written to cover the line design practices and spacers most commonly used at the time of writing. There may be other spacers available for which the specific tests reported in this standard may not be applicable. In many cases, test procedures and test values are left to agreement between purch

32、aser and supplier and are stated in the procurement contract. The purchaser is best able to evaluate the intended service conditions, which should be the basis for establishing the test severity. In Annex A, the minimum technical details to be agreed between purchaser and supplier are listed. 2 Norm
