GB/T 21067-2025Electrical equipment of industrial machines - Electromagnetic compatibility - General requirements for immunity (English PDF)

1 Scope

This document specifies the general electromagnetic compatibility immunity requirements for electrical, electronic and system components of industrial machinery.

This document applies to industrial machinery, electrical equipment, and systems, or electrical appliances, for which there are currently no specific product or product category immunity standards.

The components of the equipment and system shall have a nominal power supply voltage not exceeding 1000Va.c. or 1500Vd.c. and a nominal frequency not exceeding.200Hz.

Note 1.If relevant specific product or product category electromagnetic compatibility (EMC) immunity standards already exist, the product standard or product category standard will take precedence over this standard in all aspects.

document.

Note 2.The general immunity requirements for industrial machinery electrical, electronic equipment, and systems in this document are to ensure that they have appropriate immunity levels. However, these...

The immunity levels do not cover extreme cases with very low probability of occurring in all locations. The immunity tests in this document do not cover all...

Electromagnetic interference phenomena refer only to those relevant to this document.

Note 3.This document specifies the testing requirements for each port considered. This document does not include safety considerations.

Note 4.In some special cases, the interference level may exceed the test level specified in this document. For example, when installed near GB 4824-

The.2019 regulations specify the use of handheld transmitters in industrial, scientific, and medical (ISM) radio frequency equipment within industrial mechanical electrical systems or near electrical systems.

Machine. If necessary, consider taking specific mitigation measures.
