标准范围

适用于住宅、商业和轻工业环境中使用的电视广播接收器、声音广播接收器和相关设备。描述了适用于声音和电视接收器以及相关设备的干扰信号抗扰特性的测量方法和规定限值。本标准也适用于用于个人接收的直接到家（DTH）卫星接收系统室外单元的抗扰度。抗扰度要求在0 Hz至400 GHz的频率范围内给出。不要求在规定频带外或与本标准规定以外的其他现象有关的射频测试。本标准的目的是定义范围内定义的设备的抗扰度试验要求，包括静电放电在内的连续和瞬态、传导和辐射干扰。这些试验要求代表了基本的电磁抗扰度要求。对每个考虑的端口（外壳或连接器）规定了测试要求。本标准涵盖的环境包括住宅、商业和照明-工业场所，包括室内和室外。以下列表虽然不全面，但给出了所包括的位置:-住宅物业，如房屋、公寓等。；-零售店，如商店、超市等。；-营业场所，如办公室、银行等。；-公共娱乐场所，如电影院、公共酒吧、舞厅等。；-户外场所，如加油站、停车场、娱乐和体育中心等。；-轻工业场所，如车间、实验室、服务中心等。;-汽车和船。以公共电网低压直接供电为特点的场所被视为住宅、商业或轻工业场所。

Applies to television broadcast receivers, sound broadcast receivers and associated equipment intended for use in the residential, commercial and light industrial environment.Describes the methods of measurement and specified limits applicable to sound and television receivers and to associated equipment with regard to their immunity characteristics to disturbing signals.This standard is also applicable to the immunity of outdoor units of direct to home (DTH) satellite receiving systems for individual reception.Immunity requirements are given in the frequency range 0 Hz to 400 GHz. Radio-frequency tests outside the specified frequency bands or concerning other phenomena than given in this standard are not required.The objective of this standard is to define the immunity test requirements for equipment defined in the scope in relation to continuous and transient, conducted and radiated disturbances including electrostatic discharges.These test requirements represent essential electromagnetic immunity requirements.Test requirements are specified for each port (enclosure or connector) considered.The environments encompassed by this standard are residential, commercial and light-industrial locations, both indoor and outdoor. The following list, although not comprehensive, gives an indication of locations which are included:- residential properties, e.g. houses, apartments, etc.;- retail outlets, e.g. shops, supermarkets, etc.;- business premises, e.g. offices, banks, etc.;- areas of public entertainment, e.g. cinemas, public bars, dance halls, etc.;- outdoor locations, e.g. petrol stations, car parks, amusement and sports centres, etc.;- light-industrial locations e.g. workshops, laboratories, service centres, etc.;- car and boat.Locations which are characterized by their mains power being supplied directly at low voltage from the public mains are considered to be residential, commercial or light industrial.
