Scope

This standard specifies the general immunity requirements for industrial mechanical electrical and electronic equipment and systems (hereinafter referred to as "equipment"), and provides requirements for working under continuous, transient, conducted and radiated disturbances and electrostatic discharges. Requirements for the immunity test of the equipment. This standard is applicable to industrial mechanical electrical, electronic equipment and systems or components of electrical equipment and systems for which there is no specific product or product category immunity standard, and its rated voltage does not exceed AC l 000 V, DC l 500 V and rated frequency Not to exceed 200 Hz. If there are related special products or product-type electromagnetic compatibility (EMC) immunity standards, the product standards or product-type standards will take precedence over this general standard in all aspects. The general immunity requirements of this standard for industrial mechanical electrical and electronic equipment and systems are to ensure that they have a suitable immunity level. However, these immunity levels do not cover some extreme conditions which may occur at any location with a very low probability. The immunity test of this standard does not include all electromagnetic disturbance phenomena, but only involves the electromagnetic disturbance phenomena related to this standard. This standard specifies test requirements for each type of port considered. Note 1: This standard does not include considerations of safety aspects. Note 2: In some special cases, the disturbance level may exceed the test level specified in this standard. For example, the electrical system of industrial machinery installed near the industrial, scientific and medical (ISM) radio frequency equipment specified in GB 4824 or the use of hand-held transmitters near the electrical system. In some cases, specific mitigation measures should be taken.
