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.
