Scope

This standard applies to sound and television broadcast receivers and related equipment used in residential, commercial and light industrial environments. This standard specifies the immunity limits and measurement methods of sound and television receivers and related equipment to radio disturbance signals. This standard also applies to the immunity of direct-to-home (DTH) outdoor units of satellite reception systems for personal reception. The frequency range of this standard is from 0Hz to 400GHz, and there is no requirement for radio frequency testing or related phenomena outside this frequency band. The purpose of this standard is to specify the requirements for immunity testing of the above-mentioned equipment to continuous or transient conducted and radiated disturbances and to electrostatic discharge. These test requirements represent basic electromagnetic immunity requirements. These test requirements consider each port (both housing and connection ends). The environments to which this standard applies are residential areas, commercial areas and light industrial areas, including indoors and outdoors. The following places are listed as representatives, including: — residential places, such as houses, apartments, etc.; — retail Outlets, such as shops, supermarkets, etc.; ——Commercial places, such as offices, banks, etc.; ——Public entertainment places, such as cinemas, bars, dance halls, etc.; ——Outdoor places, such as gas stations, parking lots, entertainment venues, etc. and sports centers, etc.; - Light industrial sites, such as workshops, laboratories, service centers, etc.; - Vehicles and ships. Sites that are directly powered by the public low-voltage power supply system are considered residential, commercial, and light industrial areas.
