IEC 63180-2020 Methods of measurement and declaration of the detection range of detectors- Passive infrared detectors for major and minor motion detection.
This document provides a methodology and test procedures to be able to declare and verify the detection area for motion detectors using passive infrared technology in electronic control devices and appliance switches,， whether standalone (direct control of one or more applications) or as part of home and building electronic systems or building automation control systems (HBES/BACS) or similar.
It also provides a uniform way to present the test results.
The purpose of these detectors is to detect the major and minor movements of persons.

3 Trms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and 1EC maintain terminological databases for use in standardization at the following addresses:

3.1 infrared
optical radiation for which the wavelengths in vacuum are longer than those for visible radiation, that is approximately between 780 nm and 1 mm
[SOURCE: IEC 60050-731:1991, 731-01-05]
3.2 passive infrared detector
electronic detector that measures infrared (IR) light radiating from humans in its field of view
3.3  motion detector
unit detecting motion that can be part of an electronic control device or an appliance switch
Note 1 to entry: “Electronic control device” is used as a general term to cover electronic switches, HBES/BACS switches and electronic extension units.
3.4 major motion
movement of a person walking into an area or walking within an area
4 General requirements on tests
Detectors shall be mounted and installed according to the manufacturer’s instructions.
Manufacturer’s instructions regarding operation shall be applied to all tests, where applicable.
It is allowed to set the delay-time of detectors at minimum setting or in test mode. The sensitivity is set at maximum.
NOTE A modification of the detector software with a minimum value of 5 s for the delay-time can be necessary to shorten the test time in total.
During the test, the detectors shall be able to activate the load independently of the light level in the test room.
The dead time of the detector shall be considered according to the manufacturer’s instructions. The timing of any persons’ (dummy) movement and any test arm movement shall be adjusted accordingly.
Tests according to this document are type tests.
NOTE Type tests are defined in IEC 60050-581:2008, 581-21-08.
For detectors installed in an HBES/BACS， a minimum configuration is built to test the performance of the detectors. The digital output signal is monitored to verify the activation of the detectors or a load can be switched in the HBES/BACS. In the latter case the dead time of the HBES/BACS shall be taken into consideration.
The major motion test can be executed via a human walking test or via an automated test system as described in this document.
5 Test environment
The general ambient conditions in the test room shall be as follows:
relative humidity
maximum 70 % RH.
The size of the room shall be large enough in order not to influence the test result.
The walls of the test room, if located within the coverage area of the detector, shall not influence the result.
NOTE This can be achieved by covering the detection area of the detector towards the wall or by covering the wall with a coating or a curtain.
During the tests, air movement (for example, air-conditioning) shall not affect the results; and the walls, floor and ceilings shall have a negligible effect on the reflection in the infrared range.
The room shall be a closed room and daylight entrance shall be limited. Direct sunlight on the test area is not allowed.
The use of artificial light shall not contain an IR component.
NOTE Artificial light without an IR component can be achieved using LED technology.
The supply voltage to the detector shall meet the following requirements:
voltage stability +3 %;
frequency stability +2 %;IEC 63180 pdf download.
