36、This particular standard amends and supplements IEC 60601-1:2005 (third edition): Medical Electrical Equipment Part 1: General requirements for basic safety and essential performance. The requirements of this particular standard should be taken as the minimum to comply with, in order to achieve a re
37、asonable level of safety and reliability during operation and application of non-laser light source equipment intended for therapeutic, diagnostic, monitoring and cosmetic/aesthetic use. An asterisk (*) notes clauses for which there is rationale comment in Annex AA. It is considered that knowledge o
38、f the reasons for these requirements will facilitate the proper application of this particular standard and be of use in any revision that may be necessitated by changes in clinical practice or as a result of developments in technology.

40、ollows: 201.1.1 Scope Replacement: This International Standard applies to BASIC SAFETY and ESSENTIAL PERFORMANCE of equipment incorporating one or more sources of OPTICAL RADIATION in the wavelength range 200 nm to 3 000 nm, with the exception of laser radiation, and intended to create non-visual ph
41、oto-biological effects in humans or animals for therapeutic, diagnostic, monitoring, cosmetic/aesthetic or veterinary applications; hereafter referred to as light source equipment (LS EQUIPMENT). This particular standard does not apply to equipment for sun tanning, for ophthalmic instruments or for
42、infant phototherapy. NOTE Safety requirements in this particular standard are intended to address only HAZARDS to the eye and skin; hazards to internal tissues are not included in its scope. LS EQUIPMENT may consist of a single or multiple sources of OPTICAL RADIATION, with or without power supply,
43、or may be incorporated into a complex system that includes optical, electrical or mechanical systems or sources of other radiation. NOTE Annexes AA to EE have been included for purposes of general guidance and to illustrate many typical cases. However, the annexes should not be regarded as definitiv
44、e or exhaustive. 201.1.2 Object Replacement: The objects of this particular standard are: to establish optical radiation safety, basic safety and essential performance requirements for LS EQUIPMENT; to specify requirements for the MANUFACTURER to supply information and establish procedures so that p
45、roper precautions can be adopted; to provide warning to individuals of HAZARDS associated with accessible OPTICAL RADIATION from LS EQUIPMENT through signs, labels and instructions; to reduce the possibility of injury by minimizing unnecessary accessible OPTICAL RADIATION; to provide means of improv
46、ed control of the HAZARDS related to OPTICAL RADIATION through protective features and to assist safe use of LS EQUIPMENT; _ 1)The general standard is IEC 60601-1:2005, Medical electrical equipment Part 1: General requirements for basic safety and essential performance.

47、57 IEC:2011 9 to protect persons against other HAZARDS resulting from the operation and use of LS EQUIPMENT. 201.1.3 Collateral standards Addition: This particular standard refers to those applicable collateral standards that are listed in Clause 2 of the general standard and in Clause 201.2 of this
48、 particular standard. All published collateral standards in the IEC 60601 series apply as published. 201.1.4 Particular standards Replacement: In the IEC 60601 series, particular standards may modify, replace or delete requirements contained in the general standard and collateral standards as approp
49、riate for the particular ME EQUIPMENT under consideration, and may add other basic safety and essential performance requirements. A requirement of a particular standard takes priority over the general standard. For brevity, IEC 60601-1 is referred to in this particular standard as the general standard. Collateral standards are referred to by their document number. The numbering of clauses and subclauses of this
