100 FOREWORD

101 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

102 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

103 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

104 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

105 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

106 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

107 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

108 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

109 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

110 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

111 consensus of opinion on the relevant subjects since each technical committee has representation from all

112 interested IEC National Committees.

113 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

114 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

115 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

116 misinterpretation by any end user.

117 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

118 transparently to the maximum extent possible in their national and regional publications. Any divergence between

119 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

120 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

121 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

122 services carried out by independent certification bodies.

123 6) All users should ensure that they have the latest edition of this publication.

124 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

125 members of its technical committees and IEC National Committees for any personal injury, property damage or

126 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

127 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

128 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

129 indispensable for the correct application of this publication.

130 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

131 rights. IEC shall not be held responsible for identifying any or all such patent rights.

178 INTRODUCTION

179 This particular standard amends and supplements IEC 60601-1:2005+AMD1:2012+AMD2:2020

180 Medical Electrical Equipment – Part 1: General requirements for basic safety and essential

181 performance.

182 This edition of the standard constitutes a major review of the previous edition and covers the

183 recent development of LS EQUIPMENT. It now includes the Risk Group 1C (RG-1C). LS EQUIPMENT

184 of RG-1C incorporates technical means which inhibit emission into free space when the

185 APPLICATOR is not in GOOD CONTACT with the target tissue.

186 It now excludes LS EQUIPMENT of RG-1 and RG-2 as these are assumed to represent no hazard.

187 RG-1C is only included if the incorporated light source is of RG-3.

188 This edition of the standard clarifies its relation to the concept of Risk Groups (RGs), as

189 introduced in IEC 62471-1. The information about classification and rules for the determination

190 of Risk Groups is now linked to IEC 62471-1.

191 Although this particular standard was applicable to LS EQUIPMENT containing UV sources, more

192 emphasis was given to UV applications of the equipment than in the previous edition.

193 This edition of the standard now excludes LS EQUIPMENT which is intended to be used on animals.

194 The requirements of this particular standard should be taken as the minimum to comply with, in

195 order to achieve a reasonable level of safety and reliability during operation and application of

196 non-laser light source equipment intended for therapeutic, diagnostic, monitoring and

197 cosmetic/aesthetic use.

198 An asterisk (*) notes clauses for which there is rationale comment in annex AA. It is considered

199 that knowledge of the reasons for these requirements will facilitate the proper application of this

200 particular standard and be of use in any revision that may be necessitated by changes in clinical

201 practice or as a result of developments in technology.

210 201.1 Scope, object and related standards
211 Clause 1 of the general standard applies, except as follows:
212 201.1.1 *Scope
213 Replacement:

214 This particular Standard applies to BASIC SAFETY and ESSENTIAL PERFORMANCE of equipment

215 incorporating one or more sources of OPTICAL RADIATION in the wavelength range 200 nm to

216 3 000 nm, with the exception of laser radiation, and intended to create photobiological effects

217 in humans for therapeutic, diagnostic, monitoring, or cosmetic/aesthetic applications; hereafter

218 referred to as light source equipment (LS EQUIPMENT).

219 This particular standard applies to LS EQUIPMENT of Risk Group 1C (but only if the embedded

220 source of OPTICAL RADIATION is of RG-3), and of Risk Group 3.
221 Note: Classification rules for Risk Groups, see 201.6.1.102

222 This particular standard does not apply to equipment for sun tanning such as sunlamp products,

223 for ophthalmic instruments, for lighting purposes in medical/cosmetic environments, for

224 photography/video, for equipment which produces visual or non-visual effects such as circadian

225 entrainment, or for infant phototherapy and infant radiant warmers. This particular standard

226 does not apply to sterilisation equipment.

227 This particular standard does not apply to home-use appliances. It does not apply to home light

228 therapy equipment, such as equipment which is intended to be used in the HOME HEALTHCARE

229 ENVIRONMENT and is typically used by a LAY OPERATOR.

230 Note: Home-use appliances are covered by IEC 60335-2-113:2016. Appliances for skin exposure to OPTICAL

231 RADIATION, such as sunlamp products are covered by IEC 60335-2-27. Home light therapy equipment providing light

232 therapy by means of eye-mediated photobiological effects, which can be visual or non-visual, and skin-mediated

233 photobiological effects, possible applications including pain relief, psoriasis treatment, and treatment of winter

234 depression (SAD), is covered by IEC 60601-2-83:2019. See Bibliography.

235 Note: Safety requirements in this particular standard are intended to address only HAZARDS to the eye and superficial

236 tissues including skin or mucosa. As OPTICAL RADIATION does not penetrate more than a few mm in tissue, HAZARDS

237 to underlying tissues are not considered.
238 201.1.2 Object
239 Replacement:
240 The objects of this particular standard are:

241 – to establish the risk from OPTICAL RADIATION, specify basic safety and essential performance

242 requirements for LS EQUIPMENT;

243 – to specify requirements for the MANUFACTURER to supply information and establish

244 procedures so that proper precautions can be adopted;
––––––––––

The general standard is IEC 60601-1:2005, including Amendment 1:2012 and Amendment 2:2020, Medical electrical equipment

IEC CDV 60601-2-57 ED2  IEC:2022 -9- 76/706/CDV

245 – to provide warning to individuals of risks associated with accessible OPTICAL RADIATION from

246 LS EQUIPMENT through signs, labels and instructions;

247 – to reduce the possibility of adverse effects and injuries by minimizing unnecessary

248 accessible OPTICAL RADIATION; to provide means of improved control of the HAZARDS related

249 to OPTICAL RADIATION through engineering controls;

250 – to specify requirements for protection against other HAZARDS resulting from the operation

251 and use of LS EQUIPMENT.
252
253 201.1.3 Collateral standards
254 Addition:

255 This particular standard refers to the applicable collateral standards that are listed in Clause 2

256 of the general standard.
257 All collateral standards apply, except IEC 60601-1-11 which does not apply.
258 201.1.4 Particular standards
259 Replacement:

260 In the IEC 60601 series, particular standards may modify, replace or delete requirements

261 contained in the general standard and collateral standards as appropriate for the particular

262 ME EQUIPMENT under consideration, and may add other basic safety and essential performance

263 requirements.

264 A requirement of a particular standard takes priority over the general standard.

265 For brevity, IEC 60601-1 is referred to in this particular standard as the general standard.

266 Collateral standards are referred to by their document number.

267 The numbering of clauses and subclauses of this particular standard corresponds to that of the

268 general standard with the prefix “201” (e.g. 201.1 in this particular standard addresses the

269 content of Clause 1 of the general standard) or applicable collateral standard with the prefix

270 “20x” where x is the final digit(s) of the collateral standard document number (e.g. 202.4 in this

271 particular standard addresses the content of Clause 4 of the 60601-1-2 collateral standard,

272 203.4 in this particular standard addresses the content of Clause 4 of the 60601-1-3 collateral

273 standard, etc.). The changes to the text of the general standard are specified by the use of the

274 following words:

275 "Replacement" means that the clause or subclause of the general standard or applicable

276 collateral standard is replaced completely by the text of this particular standard.

277 "Addition" means that the text of this particular standard is additional to the requirements of the

278 general standard or applicable collateral standard.

279 "Amendment" means that the clause or subclause of the general standard or applicable

280 collateral standard is amended as indicated by the text of this particular standard.

281 Subclauses, figures or tables which are additional to those of the general standard are

282 numbered starting from 201.101. However, due to the fact that definitions in the general

283 standard are numbered 3.1 through 3.139, additional definitions in this particular standard are

284 numbered beginning from 201.3.201. Additional annexes are lettered AA, BB, etc., and

285 additional items aa), bb), etc.

286 Subclauses, figures or tables which are additional to those of a collateral standard are

287 numbered starting from 20x, where “x” is the number of the collateral standard, e.g. 202 for IEC

288 60601-1-2, 203 for IEC 60601-1-3, etc.

289 The term "this standard" is used to make reference to the general standard, any applicable

290 collateral standards and this particular standard taken together.

291 Where there is no corresponding clause or subclause in this particular standard, the clause or

292 subclause of the general standard or applicable collateral standard, although possibly not

293 relevant, applies without modification; where it is intended that any part of the general standard

294 or applicable collateral standard, although possibly relevant, is not to be applied, a statement

295 to that effect is given in this particular standard.
