CSA Preface 

This is the third edition of CSA C22.2 No. 60601-2-21, Medical electrical equipment — Part 2-21: Particular requirements for the basic safety and essential performance of infant radiant warmers, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60601-2-21 (third edition, 2020-09). It supersedes the previous edition, published in 2010 as CAN/CSA-C22.2 No. 60601-2-21 (adopted IEC 60601-2-21:2009). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. For brevity, this Standard will be referred to as "CSA C22.2 No. 60601-2-21" throughout. This Standard is intended to be used in conjunction with CAN/CSA-C22.2 No. 60601-1:14, Medical electrical equipment — Part 1: General requirements for basic safety and essential performance (adopted IEC Standard 60601-1:2005, including Amendment 1:2012, with Canadian deviations). This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Consumer and Commercial Products, under the jurisdiction of the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. Due to the medical content of this Standard, it was also approved by the CSA Technical Committee on Application of Electricity in Health Care, under the jurisdiction of the CSA Strategic Steering Committee on Health and Well-being. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope and object Clause 1 of the general standard1 applies, except as follows: 

201.1.1 * Scope Replacement: 

This part of IEC 60601 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of INFANT RADIANT WARMERS as defined in 201.3.204, also referred to as ME EQUIPMENT. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME EQUIPMENT and to ME SYSTEMS, as relevant. HAZARDS inherent in the intended physiological function of ME EQUIPMENT or ME SYSTEMS within the scope of this document are not covered by specific requirements in this document, except in 7.2.13 and 8.4.1 of the general standard. 

NOTE See also 4.2 of the general standard. 

This particular standard specifies the safety requirements for INFANT RADIANT WARMERS, but alternate methods of compliance with a specific clause, by demonstrating equivalent safety, will not be judged as non-compliant, if the MANUFACTURER has demonstrated in his RISK MANAGEMENT FILE that the RISK presented by the HAZARD has been found to be of an acceptable level when weighed against the benefit of treatment from the device. This particular standard does not apply to: 

• devices supplying heat via BLANKETS, PADS or MATTRESSES in medical use; for information, see IEC 60601-2-35; 

• INFANT INCUBATORS; for information, see IEC 60601-2-19; • INFANT TRANSPORT INCUBATORS, for information, see IEC 60601-2-20;

• INFANT PHOTOTHERAPY EQUIPMENT, for information, see IEC 60601-2-50. SKIN TEMPERATURE SENSORS which are applied to operate a BABY CONTROLLED RADIANT WARMER including the displayed value are not considered to be a CLINICAL THERMOMETER in the sense of the particular standard ISO 80601-2-56. 

201.1.2 Object Replacement: 

The object of this particular standard is to establish particular BASIC SAFETY and ESSENTIAL PERFORMANCE requirements for INFANT RADIANT WARMERS as defined in 201.3.204, which minimize HAZARDS to PATIENT and OPERATOR, and to specify tests by which compliance with the requirements can be verified.
