Passive infrared detectors for major and minor motion detection
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION

Passive infrared detectors are an important element in an energy efficient building. They allow

for switching on and off and for controlling loads in order to achieve an optimum degree of

comfort and energy efficiency.

The detectors covered in this document are motion detectors using passive infrared (PIR)

technology in electronic control devices and appliance switches whether stand-alone (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. In the case of HBES/BACS, the

resulting action depends on the programming of the relevant HBES/BACS.
The purpose of these detectors is to detect the movement of persons.

Detectors linked to a system may also be assigned other tasks: state reporting, power

consumption, event reporting, scenarios, etc. These additional functions are not part of this

document.

In order to achieve the energy efficiency targets and comfort, the detectors should operate

accurately. In addition, the detection area will need to be provided with sufficient accuracy in

order to allow integrators to choose the correct detectors for the needed action.

This document provides a methodology and test procedures for a manufacturer to declare and

verify the detection performance of these devices with respect to the detection area.

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.
---------------------- Page: 13 ----------------------
SIST EN IEC 63180:2021
– 10 – IEC 63180:2020 © IEC 2020

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:
– temperature 18 °C to 23 °C;
– 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 %;
– total harmonic distortion 5 %.

The temperature measurements shall be taken at 1,7 m ± 5 cm height from the floor. The

temperature measurement shall be performed as close as possible to the centre of the

expected detection area.

The temperature of walls, ceiling and floor of the test room shall be allowed to stabilize prior

to testing.

NOTE It can be required to set the test room temperature several hours prior to testing.

The test room temperature and the temperature of the walls, ceiling and floor shall be stable

within a tolerance of ±2 K during the tests.

When using test dummies and test arms to perform the tests, the difference between the

temperature of these tools and that of the test room shall be stable during the tests within a

tolerance of ±2 K.
There shall be no other people or moving objects in the coverage area.

6 Test equipment
6.1 Test person for major motion detection
The test person shall meet the following criteria:
– height: 1,7 m ± 10 cm;
– weight: 70 kg ± 10 kg.

The test person shall be dressed in tight fitting clothes with the hands and head exposed (e.g.

bicycling clothes, running clothes) in such a way that, when measured with infrared camera on

one point of the body, in the vicinity of the belly button, the test person achieves a

temperature average of 7 K ± 2 K above the ambient temperature of the room.

NOTE The 7 K delta value was found to be the average surface temperature of people with only the head and

hands exposed.
6.2 Test dummies for major motion detection when using automated test systems
For testing the detection area, a test dummy as given in Figure 4 shall be used.
Figure 4 – Test dummy perspective view

For detectors with an installation height up to and including 3 m, a full-size test dummy as

given in Figure 5 shall be used. Providing that a sufficiently large testing room is available, a

full-size dummy can also be used for testing higher installation heights. If the test room is not

large enough, smaller test dummies can be used as given in Figure 6 and Figure 7, and shall

be chosen according to Table 1.

Figure 7 – Scaled 1:5 test dummy for testing motion detection

The test dummies are built in accordance with Figure 5 to Figure 7. The temperature of each

zone (head, body and legs) can be controlled separately as follows:

The head is heated to a temperature of 14 K ± 1 K above the ambient temperature of the test

room.

The body and legs are heated to a temperature of 7 K ± 1 K above the ambient temperature of

the test room.

All test sides of the dummies shall be heated except the back side and the bottom side, which

are not relevant for the test.

The temperature of the surface for each zone of the dummy shall be homogeneous and the

spread shall be ≤ 1,5 K.

NOTE The dummy can be made of aluminium, painted black and heated by heating plates placed inside the

dummy.

The temperature of the dummy shall be stable for a minimum of 10 min prior to testing and for

the duration of the tests.
The weight of the test dummy is irrelevant.

A full size dummy can be used for testing real installation height, providing that a sufficiently

large testing room is available; otherwise, for testing different mounting heights or simulated

mounting heights, the test dummy shall be chosen according Table 1.
