It is identical with IEC 60601-2-25:1993 Medical electrical equipment - Part 2: Particular requirements for the safety of electrocardiographs, including amendment 1:1999, published by the International Electrotechnical Commission (IEC). This Particular Standard
16、 amends and supplements BS EN 60601-1:1990 hereinafter called the General Standard. As stated in 1.3 of the General Standard, the requirements of this Particular Standard take precedence over those of the General Standard. As in the General Standard, the requirements are followed by compliance tests
17、. The numbers of the sections and clauses in this standard refer to the related sections and clauses in the General Standard. Clauses, subclauses or figures that are additional to those of the General Standard are numbered starting from 101; additional appendices are lettered AA, BB, etc., and addit
18、ional items are lettered aa), bb), etc. The changes from the text of the General Standard are specified by the use of the following words. “Replacement” means that the clause, subclause or specified paragraph of the General Standard is replaced by the text of this standard. “Amendment” means that th

21、is indicated in the text by tags B M. Tags indicating changes to IEC text carry the number of the IEC amendment. For example, text altered by IEC amendment 1 is indicated byB M. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been r
22、enumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Additional information.

40、detachable ELECTROCARDIOGRAMS for diagnostic purposes. It also applies to vector-cardiographs and EQUIPMENT for stress testing. This Particular Standard covers minimum safety requirements. Special requirements concerning use in ambulances, phono-cardiographs, cardiographic monitors, polygraphs, tele
41、metering, special tests (for example, His bundle electrocardiographs), etc. are not covered by this Particular Standard. EQUIPMENT with microelectrodes used directly in the fibres of the heart muscle is also excluded. 1.2 Object Replacement: The object of this Particular International Standard is to
