EVS-EN 303 454 V1.1.1:2018

The present document specifies technical characteristics and methods of measurements for metal and object detection
sensors in the frequency range 1 kHz to 148,5 kHz.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.3] under the
conditions identified in annex A.
The size for the inductive loops covered by the present document is limited to 3 m2.
The present document does not cover other devices using the frequency range below 148,5 kHz, e.g. ETSI
EN 303 348 [i.7] (Inductive loop for hearing impaired in 0 kHz to 20 kHz), ETSI EN 303 447 [i.8] (Inductive robotic
mowers).
These radio equipment types are capable of operating in all or part of the frequency bands given in table 1.
Table 1: Permitted range of operation
Permitted range of operation
Transmit 1 kHz to 148,5 kHz
Receive 1 kHz to 148,5 kHz
NOTE: It should be noted that the frequency range between 9 kHz and 148,5 kHz is EU wide harmonised for
inductive Short Range Devices according to Decision 2017/1483 [i.2].
