This International Standard specifies a PROCESS for a MANUFACTURER to analyse, specify,
design, VERIFY and VALIDATE USABILITY, as it relates to SAFETY of a MEDICAL DEVICE. 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.
NOTE For the purposes of this standard, USABILITY (see 3.17) is limited to characteristics of the USER INTERFACE.
If the USABILITY ENGINEERING PROCESS detailed in this International Standard has been
complied with and the acceptance criteria documented in the USABILITY VALIDATION plan have
been met (see 5.9), then the RESIDUAL RISKS, as defined in ISO 14971, associated with
USABILITY of a MEDICAL DEVICE are presumed to be acceptable, unless there is OBJECTIVE
EVIDENCE to the contrary (see 4.1.2).
This International Standard does not apply to clinical decision-making relating to the use of a
MEDICAL DEVICE.
