CSA Preface 

This is consolidated edition 3.2 of CAN/CSA-C22.2 No. 60601-1-6, Medical electrical equipment - Part 1-6: General requirements for basic safety and essential performance - Collateral standard: Usability , which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60601-1-6 (edition 3:2010 consolidated with Amendment 1:2013 and Amendment 2:2020). It supersedes the second edition, published in 2008 as CAN/CSA-C22.2 No. 60601-1-6 (adopted IEC 60601-1-6:2006). 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 "CAN/CSA-C22.2 No. 60601-1-6" 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 60601-1:2005, including Amendment 1:2012, with Canadian deviations). Where differences exist between this consolidated edition and the published edition and its amendments, those documents will take precedence. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. 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 1.1 * 

Scope 

This International Standard specifies a PROCESS for a MANUFACTURER to analyse, specify, develop and evaluate the USABILITY, as it relates to BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL ELECTRICAL EQUIPMENT, hereafter referred to as ME EQUIPMENT. This USABILITY ENGINEERING PROCESS assesses and mitigates RISKS caused by USABILITY problems associated with CORRECT USE and USE ERRORS, i.e., NORMAL USE. It can be used to identify but does not assess or mitigate RISKS associated with ABNORMAL USE. If the USABILITY ENGINEERING PROCESS detailed in this collateral standard has been complied with, then the USABILITY of ME EQUIPMENT as it relates to BASIC SAFETY and ESSENTIAL PERFORMANCE is presumed to be acceptable, unless there is OBJECTIVE EVIDENCE to the contrary. NOTE Such OBJECTIVE EVIDENCE can subsequently originate from POST-PRODUCTION surveillance. 

1.2 Object The object of this collateral standard is to specify general requirements that are in addition to those of the general standard and to serve as the basis for particular standards.
