World IEC Fever Screening Standards Explained

By Charles Rollet, Published May 04, 2020, 10:04am EDT

While 'fever detection' is new to most people, the technology has been practiced for many years and has a series of international standards that we explain herein.

IPVM Image

In particular, the world's two top international standards groups, the IEC and ISO, have published 3 standards covering fever (i.e., febrile) screening:

  • IEC 80601-2-59:2017 Medical electrical equipment — Part 2-59: Particular requirements for the basic safety and essential performance of screening thermographs for human febrile temperature screening
  • ISO/TR 13154:2017 Medical electrical equipment — Deployment, implementation and operational guidelines for identifying febrile humans using a screening thermograph
  • ISO 80601-2-56:2017 Medical electrical equipment — Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement

We purchased those 3 standards for 530 Swiss Francs (~$550 USD), studied them and prepared this guide to explain how they apply to fever sceening, including:

  • Focus Area: Inner Eye, Other Areas "Unreliable"
  • ISO Face Examples Show Importance of Inner Eye
  • Eyeglasses, Hair Shouldn't Obstruct Face
  • Impact of Obstructions Shown by ISO
  • Manufacturers Contradict Standards
  • 'Face Detection' AI and Temperature Algorithms
  • Minimum Lab Accuracy Level
  • Faces Must Be Parallel to Camera
  • Minimum Face Pixel Requirements
  • Secondary Measurement Required
  • Clinical Thermometer Requirements
  • Ambient Temperature Must Be Controlled, Ensure No One Is Sweating
  • Avoid Bright Lights, A/C Drafts, Other Heat/Cold Sources
  • Secondary Screening Area Requirements
  • Fever Cams For Use "Under Indoor Environmental Conditions"
  • Long List of Facilities Recommended
  • Ease-of-Extraction Emphasized
  • No Toilets Nearby
  • Backdrop Requirements: Non-Reflective, Avoid Dark Colors
  • People Should Be Screened One-at-a-Time
  • Data Should be Kept For One Month/GDPR Impact
  • Applicability / Legality
