1 Scope

GB 23313-2009 is the Chinese national standard on electrical equipment of industrial machines - electromagnetic compatibility - emission limits, in the field of electrical engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 19 March 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2010. Classification: ICS 29.020, CCS J09. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the EMC emission limits for industrial mechanical, electrical and electronic equipment and control systems (hereinafter referred to as "equipment"). 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.
