January 2026 – New International Standard for Occupancy Sensors Published
The International Electrotechnical Commission (IEC) has published IEC 63180:2026, the latest revision of the standard for “Methods of measurement and performance criteria for occupancy sensors”. This update introduces new test methods specifically for small motion detection and presence sensing.
What’s New in IEC 63180:2026
1. Small Motion Detection Test
A new test method evaluates the sensor’s ability to detect subtle movements such as breathing, small gestures, and micro-motions. The test uses a calibrated moving target of defined size and speed, simulating the small movements of a seated person. This is particularly relevant for modern high-sensitivity sensors like Panasonic’s PaPIRs+ with 416 zones.
2. Presence Sensing (Stationary Occupant) Test
This test measures how long a sensor can maintain an “occupied” state when a person is sitting still. It uses a thermal manikin with simulated breathing motion to mimic a real human. Sensors that can maintain occupancy for extended periods receive higher ratings.
3. Environmental Immunity Tests
Updated tests for resistance to:
- Rapid temperature changes (simulating HVAC cycling)
- Air movement (fans, drafts)
- Electromagnetic interference
- Ambient light, including LED flicker and sunlight
4. Detection Zone Mapping
A standardized method for measuring and reporting detection zones, including zone density and gaps. This allows for objective comparison between different lens designs and sensor models.
5. Standardized Reporting Format
The new standard includes a recommended format for datasheets, making it easier for specifiers to compare sensors from different manufacturers.
Test Setup Requirements
The standard specifies:
- Test chamber dimensions (minimum 5m × 5m)
- Background temperature control within ±1°C
- Calibrated motion generators
- Data acquisition requirements and sampling rates
- Statistical analysis methods for test results
Implications for Manufacturers
Compliance with IEC 63180:2026 is increasingly required for building automation systems, particularly in commercial and government projects. Manufacturers must update their test procedures and datasheets to reflect the new metrics. The standard also provides a framework for making performance claims that can be objectively verified.
What This Means for Users
For specifiers and end users, the new standard means:
- Datasheets will include more meaningful performance data
- Sensors claiming “presence detection” can be objectively compared
- Easier selection of appropriate sensors for specific applications

Availability
IEC 63180:2026 is available for purchase from the IEC website and national standards bodies. Manufacturers are expected to transition to the new test methods over the next 12-18 months.
