Industrial, scientific and medical equipment - Radio-frequency disturbance characteristics - Limits and methods of measurement

This International Standard applies to industrial, scientific and medical electrical equipment
operating in the frequency range 0 Hz to 400 GHz and to domestic and similar appliances
designed to generate and/or use locally radio-frequency energy.
This standard covers emission requirements related to radio-frequency (RF) disturbances in
the frequency range of 9 kHz to 400 GHz. Measurements need only be performed in
frequency ranges where limits are specified in Clause 6.
For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations
(see Definition 3.13), this standard covers emission requirements related to radio-frequency
disturbances in the frequency range of 9 kHz to 18 GHz.
NOTE Emission requirements for induction cooking appliances are specified in CISPR 14-1 [1]1.
Requirements for ISM RF lighting equipment and UV irradiators operating at frequencies
within the ISM frequency bands defined by the ITU Radio Regulations are contained in this
standard.
Equipment covered by other CISPR product and product family emission standards are
excluded from the scope of this standard.

Industrijska, znanstvena in medicinska oprema - Karakteristike občutljivosti za radijske motnje - Mejne vrednosti in merilne metode

Ta mednarodni standard se uporablja za industrijsko, znanstveno in medicinsko električno opremo, ki deluje v frekvenčnem območju od 0 Hz do 400 GHz, ter za gospodinjske in podobne naprave, zasnovane za proizvodnjo in/ali lokalno uporabo radiofrekvenčne energije.
Ta standard obravnava zahteve glede oddajanja motenj v povezavi z radiofrekvenčnimi (RF) motnjami v frekvenčnem območju od 9 kHz do 400 GHz. Meritve je treba opraviti samo v frekvenčnih obsegih, za katere so podane omejitve v točki 6.
Za načine uporabe ISM RF s pomenom definicije iz Pravilnika o radiokomunikacijah Mednarodne telekomunikacijske zveze (glej definicijo 3.13) ta standard obravnava zahteve glede oddajanja motenj v povezavi z radiofrekvenčnimi motnjami v frekvenčnem območju od 9 kHz do 18 GHz.
OPOMBA: Zahteve glede oddajanja motenj za indukcijske kuhalnike so podane v standardu CISPR 14-1 [1]1. Ta standard zajema zahteve za opremo za razsvetljavo ISM RF in UV-iradiatorje, ki delujejo pri frekvencah znotraj frekvenčnih pasov ISM, določenih v Pravilniku o radiokomunikacijah Mednarodne telekomunikacijske zveze.
Oprema, zajeta v drugih standardih CISPR o oddajanju motenj izdelkov in skupin izdelkov, ne spada na področje uporabe tega standarda.

Endorsement notice

The text of the International Standard CISPR 11:2015 was approved by CENELEC as a European

Standard with agreed common modifications.
COMMON MODIFICATIONS
4 Frequencies designated for ISM use
Replace Clause 4 by the following:
4 National measures and frequencies designated for ISM use

Certain frequencies are designated by the International Telecommunication Union (ITU) for use as

fundamental frequencies for ISM RF applications (see also definition 3.13). These frequencies are

listed in Table 1.

245 000 244 000 – 246 000 Under consideration 5.138
Resolution No. 63 of the ITU Radio Regulations applies.

The term “unrestricted” applies to the fundamental and all other frequency components falling within the designated

band. Outside of ITU designated ISM bands the limits for the disturbance voltage and radiation disturbance in this

standard apply.

In some CENELEC countries, different or additional frequencies may be designated for use with

ISM RF applications in the meaning of the definition found in the ITU Radio Regulations, see

definition 3.13. These frequencies are listed in Table ZB.1 (see Annex ZB).

The limits for the disturbance voltage and radiation disturbance defined in this standard do also not

apply to the fundamental ISM frequencies listed in Table ZB.1. If ISM RF applications use fundamental

frequencies other than the ITU or nationally designated frequencies, then the limits for the disturbance

voltage and radiation disturbance of this standard apply also to these fundamental frequencies.
