This standard specifies the EMC emission limits for industrial mechanical, electrical and electronic equipment and control systems (hereinafter referred to as and quot;equipment and quot;). This standard applies to industrial machinery electrical, electronic equipment, control systems or components of electrical (electronic equipment) and control systems, whose rated power supply voltage does not exceed AC 1000 V or DC 1500 V, meanwhile the rated frequency does not exceed 200 Hz. If there are related special products or product-type electromagnetic compatibility (EMC) emission standards, the product standards or product-type standards will take precedence over this standard, in all aspects. The electromagnetic emission limits and measurement methods, which are stipulated in this standard, reflect the basic electromagnetic compatibility requirements. After selection, it can ensure that the electromagnetic disturbance, which is generated by equipment working normally in industrial places, will not hinder the normal operation of other equipment. This standard specifies test requirements for each type of port considered. Note 1: When the equipment is used, within 30 m from the receiving antenna of a radio or television receiver, the limits specified in this standard may not adequately protect them from interference. Note 2: In special cases, such as when highly sensitive devices are used nearby, in order to avoid interference with them, it may be necessary to adopt additional attenuation measures to the equipment, in order to further reduce electromagnetic emissions to lower than the specified limits.
