34、 Directive 93/42/EEC except as follows: Essential Requirement 6a Essential Requirement 7.1 Essential Requirement 7.4 Essential Requirement 7.5 paragraph 2 INFANT INCUBATORS; for information see IEC 60601-2-19; INFANT TRANSPORT INCUBATORS; forinformation, see IEC 60601-2-20; INFANT RADIANTWARMERS;for
35、 information see IEC 60601-2-21. 201.1.2 ObjectReplacement:The object of this particular standard is to establishparticular BASIC SAFETY and ESSENTIALPERFORMANCE requirements for INFANT PHOTOTHERAPY EQUIPMENT (as defined in201.3.203), which reduce the safety HAZARDS to PATIENTS and OPERATORS as much
36、 as possible and tospecify tests for demonstrating compliance with theserequirements. 1) The general standard is IEC 60601-1:2005, Medical electrical equipment Part 1: General requirements forbasic safety and essential performance. 8 BS EN 60601-2-50:2009+A11:2011 EN 60601-2-50:2009+A11:2011 (E)201.

39、QUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIALPERFORMANCE requirements.Arequirement of a particularstandard takes priority overthe general standard.For brevity, IEC60601-1 is referred to in this particular standard as the general standard. Collateral standardsare referred
40、 to bytheir document n umber. Thenumbering of clauses and subclauses of this particular standard corresponds to thatofthegeneral standardwiththe prefix “201” (e.g. 201.1 in this standard addresses the contentof Clause1of the general standard)orapplicable collateral standard with the prefix “20x”wher
41、e x is the final digit(s) of the collateral standard document number (e.g. 202.4 in thisparticular standard addresses the content of Clause4 of the IEC 60601-1-2 collateralstandard, 203.4 in this particular standard addresses the contentof Clause 4 of the IEC60601-1-3 collateral standard, etc.). The
42、 changes to the textof the general standard are specified by the useof the following words:“Replacement“ means that the clause or subclause of the ge neral standard or applicable collateral standard isreplacedcompletely by the text of this particularstandard.“Addition“ means that the text of this pa
43、rticular standard is additional to the requirements ofthegeneral standard or applicable collateral standard.“Amendment“ means that the clause or subclause of the general standard or applicablecollateralstandard is amended as indicated by the text ofthis particular standard.Subclauses, figures or tab
44、les which are additional to those of the general standard arenumbered starting from201.101. However, due to the fact that definitions in the general standard are numbered 3.1 through 3.139, additional definitions in this standard arenumbered beginning from 201.3.201. Additionalannexes are lettered A
45、A, BB, etc., and additional items aa), bb) , etc.Subclauses or figures which areadditional tothose ofa collateral standard are numberedstarting from 20x, where “x” is the number of the collateral standard, e.g. 202 for IEC 60601-1-2, 203 for IEC 60601-1-3, etc. 2) IEC 60601-1-10:2007, Medical electr
