4 disturbance limit
It is not necessary to measure RF disturbances below 148.5 kHz and above 1000 MHz. The requirements for induction cookware are given in Appendix B.
4.1 Continuous harassment
Motors with commutator and other devices housed in household appliances, power tools and the like may cause continuous disturbance.
Continuous disturbances may be broadband, such as those caused by mechanical switches, commutators, and semiconductor regulators; they may also be narrow-band,
Caused by electronic control devices such as microprocessors.
Note. The concepts of “broadband harassment” and “narrowband harassment” are not used in this section. The difference between the two types of harassment is determined by the type of detector used. For this purpose, respectively
The limits measured with quasi-peak detectors and average detectors are specified (see 5.1.1 and 6.1.1).
