CISPR 14-2: Electromagnetic compatibility - Part 2: Immunity

CISPR 14-2 deals with the electromagnetic immunity of appliances and similar apparatus for household and similar purposes that use electricity, as well as electric toys and electric tools, the rated voltage of the apparatus being not more than 250 V for single-phase apparatus to be connected to phase and neutral, and 480 V for other apparatus. Apparatus may incorporate motors, heating elements or their combination may contain electric or electronic circuitry, and may be powered by the mains, by transformer, by batteries, or by any other electrical power source. Apparatus not intended for household use, but which nevertheless may require the immunity level, such as apparatus intended to be used by laymen in shops, in light industry, and on farms, are within the scope of this standard, as far as they are included in CISPR 14-1.

In addition, the following are also included in the scope of this standard:

• Microwave ovens for domestic use and catering
• Cooking hobs and cooking ovens, heated by means of RF energy
• Single- and multiple-zone induction cooking appliances
• Appliances for personal care equipped with radiators in the range from UV to IR, inclusive (this includes visible light)
• Power supplies and battery chargers provided with or intended for apparatus within the scope of this standard

For ESD tests on contacts of plugs and sockets the note ("The 4 kV contact discharge shall be applied to conductive accessible parts. Metallic contacts, such as in battery compartments or in socket outlets, are excluded from this requirement") saying that no test on contacts is necessary has been removed. The IEC 61000-4-2 includes a detailed description of how to deal with ESD on contacts and other surfaces. Also, discharge on HCP and VCP is required by the basic standard IEC 61000-4-2.
