World IEC Fever Screening Standards Explained
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.
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
