44、evious edition affect the following subjects: measurement of residual voltage; operating-duty test; pressure-relief test; standardized sparkover and residual voltages; addition of annex for information to be given on enquiries and tenders. The changes introduced are limited to the agreed upon subjec
45、ts. Additional work was not considered due to the changing technology and the present limited use of gapped surge arresters. Appendix D of the second edition of this standard has been deleted and issued as a separate Report, IEC 99-3. The present developing gapless surge arresters using metal oxide
46、resistors will be the subject of the future IEC 99-4. An application guide is under revision and will be published as IEC 99-5. It will supersede IEC 99-1A.EN 60099-1:1994 BSI 03 October 2001 5 Section 1. General 1 1.1 Scope This part of International Standard IEC 99 applies to surge protective devi
47、ces designed for repeated operation to limit voltage surges on a.c. power circuits and to interrupt power-follow current. In particular, it applies to surge arresters consisting of single or multiple spark gaps in series with one or more non-linear resistors. 1.2 Normative references The following s
48、tandards contain provisions which, through reference in this text, constitute provisions of this part of International Standard IEC 99. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part are encouraged to
