Electromagnetic Compatibility
Electromagnetic Compatibility standards, developed and published by IEC, address the emission of and immunity to radio-frequency disturbances in household appliances. Covering emission frequency ranges of 9Khz to 400Ghz, and rated voltages of not over 250V single phase or 480V for other appliances, these standards cover a very wide range of household appliances. In fact, many of these electronics have a notice written on them that refers to these emissions and immunity that the end-user can see.

Electromagnetic compatibility - Requirements for household appliances, electric tools and similar apparatus - Part 1: Emission
CISPR 14-1:2020 specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools and similar apparatus as defined below, whether powered by AC or DC (including a battery). This document is applicable to the following equipment: - household appliances or similar equipment; - electric tools; - similar apparatus. Also included in the scope of this document are separate parts of the above mentioned equipment such as motors and switching devices (e.g. power or protective relays). However, no emission requirements apply to such separate parts, unless otherwise stated in this document. Products which incorporate radio transmit/receive functions are included in the scope of this document. Equipment under the scope of this document making use of IPT is also in the scope. Excluded from the scope of this document are: - equipment for which all emission requirements in the radio-frequency range are explicitly formulated in other CISPR standards; - equipment intended to be used only on a vehicle, ship or aircraft; - equipment used only in industrial environment - the effects of electromagnetic phenomena relating to the safety of the equipment. Multifunction equipment may be required to comply with clauses in this and other standards. The details are given in 6.5. The emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU including their spurious emissions. This seventh edition cancels and replaces the sixth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant changes with respect to the previous edition: - extension of the frequency range for radiated measurements above 1 GHz; - revision of general test conditions and addition of new specific test conditions (e.g. for robotic equipment); - introduction of additional requirements for equipment making use of inductive power transfer technology; - remove from the normative text any compliance requirement based on statistical evaluation; - revision of clicks analysis, with particular relevance to the determination of the observation time and the application of the upper quartile method for different types of click analysers. Refer to the Foreword of the document for examples of equipment.

Electromagnetic compatibility - Requirements for household appliances, electric tools and similar apparatus - Part 2: Immunity - Product family standard
CISPR 14-2:2020 specifies the electromagnetic immunity requirements in the frequency range 0 Hz to 400 GHz that apply to appliances, electric tools and similar equipment as specified below, whether powered by AC or DC (including a battery). This document specifies immunity requirements for continuous and transient electromagnetic disturbances, both conducted and radiated. Unless otherwise specified, this document is applicable to all equipment in the scope of CISPR 14-1, namely: - household appliances or similar equipment; - electric tools; - similar equipment; - Refer to the Scope of the document for examples of equipment. Included in the scope of this document are also microwave ovens for domestic use or catering. Equipment which incorporate radio transmit/receive functions are included in the scope of this document. NOTE: For handling cases where equipment under the scope of this document is combined with transmit and/or receive radio functions, see Clause 8. Excluded from the scope of this document are: - equipment for which all electromagnetic immunity requirements are explicitly formulated in other CISPR or IEC standards; - equipment intended to be part of the fixed electrical installation of buildings (e.g. fuses, circuit breakers, cables and switches); - medical electrical equipment, including those in the scope of CISPR 14-1; - equipment used only in industrial environment; - equipment intended to be used exclusively in locations where special electromagnetic conditions exist (e.g. high electromagnetic fields nearby broadcast transmitting stations or high energy pulses nearby power generation stations); - equipment intended to be used exclusively on a vehicle, ship, boat or aircraft; - the effects of electromagnetic phenomena relating to the safety of apparatus (see IEC 60335 series); Also excluded from the scope of this document is AC single-phase equipment with a rated voltage higher than 250 V between phase and neutral and AC multi-phase equipment with rated voltage higher than 480 V. Abnormal operation of the equipment, such as simulated faults in the electric circuitry for testing purposes, is not taken into consideration. This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) extension of the frequency range for radiated immunity above 1 GHz; b) an advanced categorisation of equipment; c) revision of general test conditions and addition of new specific test conditions (e.g. for robotic equipment); d) clarification of requirements applicable to equipment incorporating radio functions; e) addition of requirements for wired network ports; f) revision of definitions and addition of new ones; g) delete requirements referring to statistical evaluation.
