Usability & Human Factors Testing

Evaluation of your usability engineering process and file to IEC 60601-1-6 and IEC 62366-1, with an ASCA summary test report for your FDA 510(k).

  • IEC 60601-1-6
  • IEC 62366-1
  • FDA human factors guidance

Why Sigma

Usability evidence FDA reviewers recognize

We check that your usability engineering process is complete, traceable and tied to your risk management, so the evidence holds up in review.

  • FDA ASCA-accredited for IEC 60601-1-6: your report comes with an ASCA summary test report for the 510(k).
  • Clause by clause against IEC 62366-1: use specification, user interface, hazard-related use scenarios and evaluation records.
  • Linked to risk management: we check that use errors trace to your ISO 14971 hazards and risk controls.
  • One program with IEC 60601-1: usability is evaluated together with electrical safety and the other collateral standards.

What we evaluate

Every part of your usability engineering file

Reviewed for completeness, traceability and consistency with your risk management file. See how we measure →

Use specificationIntended users, use environments, operating principle and the conditions of use
Safety-related UI characteristicsUser interface elements that can lead to use errors with harm
Known use problemsUse problems from similar devices, complaints and field data
Hazard-related use scenariosScenarios selected for evaluation and how they were prioritized
User interface specificationDesign requirements for the user interface and their traceability
Formative evaluationsRecords of early evaluations and how findings changed the design
Summative evaluationProtocol, participants, tasks, acceptance criteria and results
Accompanying documentsInstructions for use and training, evaluated as part of the user interface

Your challenges, our solutions

What manufacturers ask us most

“Our usability file was written after the design was finished.”

We show you what is missing so the file traces use scenarios to risk controls and design decisions.

“Which tasks belong in the summative test?”

We review your hazard-related use scenarios and critical tasks before you recruit participants.

“FDA asked for human factors data.”

We help you scope the human factors evidence and present it the way the FDA guidance expects.

FAQ

Frequently asked questions

Is the report accepted by FDA as an ASCA report?

IEC 60601-1-6 is within our ASCA scope, so you receive an ASCA summary test report for your 510(k).

Is IEC 60601-1-6 the same as FDA human factors validation?

They are related but not the same. IEC 60601-1-6 checks your usability engineering process through IEC 62366-1; FDA also expects human factors validation results as described in its guidance. We help you line up both so one body of evidence supports the submission.

What do I need to send?
