Standards Development

Scope

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.

NOTE 1 This includes equipment connected to high voltage supply network (greater than 1 000 V ac or 1 500 V d.c.), as well as power electronics and energy saving/production equipment. For a non-exhaustive list of equipment types that are in the scope of CISPR 37, see Annex A.

This standard sets out limits and test methods applicable when the measurements are performed in situ or at a defined site.

NOTE 2 In situ means the final installation site (the equipment’s location of use), while the defined site is usually on the manufacturer’s premises. These two terms are defined in 3.1.5 and 3.1.2, respectively.

CISPR 37 can be used, instead of CISPR 11, for example, for:

- testing equipment that cannot be evaluated on a standard test site (e.g., because of very large size or very high input power requirements); such as atypical equipment (see definition 3.1.1) connected to a low-voltage or high-voltage power supply network, including energy-saving and energy-production equipment;

- evaluation of the equipment’s emissions at the intended location of operation;

- measurements on the equipment at its actual installation following an interference complaint;

- measurements on a defined site, when using a standard test site or performing in situ measurements are both impractical.

NOTE 3 For requirements applicable to measurements on defined sites, see Clause 8.

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 of CISPR 11:2015/AMD1:2016/AMD2:2019), this standard covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz.

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 (if measured in situ or at a defined site).

Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this standard.
