Introduction

Electromagnetic compatibility is the ability of electrical and electronic equipment or systems to function properly in their electromagnetic environment without causing adverse effects to anything in that environment.

Ability to withstand electromagnetic disturbances. Electromagnetic compatibility is one of the important factors affecting the environment and product quality, and its standardization work has

aroused widespread attention at home and abroad. In this regard, the IEC 61000 series of publications developed by the International Electrotechnical Commission (IEC)

Common standards in the fields of industry, electrical engineering and energy, transportation, social undertakings and health, quality and safety of consumer goods, etc., divided into

There are six categories. overview, environment, limit values, testing and measurement techniques, installation and mitigation guidelines, and general standards. my country has launched a series of publications

The domestic transformation work has been carried out, and the corresponding national standard system has been established.

In this standard system, the "General Standard for Electromagnetic Compatibility" is a basic standard for general aspects in the field of electromagnetic compatibility, which aims to describe different

Emission and immunity requirements in the same environment, etc., are proposed to be composed of 8 parts.

--- Immunity in residential, commercial and light industrial environments (GB/T 17799.1). Intended for residential, commercial and light industrial environments

Electrical and electronic equipment used in specifies its immunity to continuous and transient, conducted and radiated disturbances, including electrostatic discharge

degree test requirements.

--- Immunity test in industrial environment (GB/T 17799.2). Intended for use in an industrial environment and does not yet have a dedicated product

The product or product-group immunity standard for electrical and electronic equipment specifies its immunity to continuous and transient, conducted and

Immunity test requirements for radiated disturbances.

--- Emissions in residential, commercial and light industrial environments (GB 17799.3). Intended for use in residential, commercial and light industrial environments

Emission test requirements for continuous and transient, conducted and radiated disturbances of electrical and electronic equipment used.

--- Emission in an industrial environment (GB 17799.4). The purpose is to specify the continuity of electrical and electronic equipment used in industrial environments

and emission test requirements for transient, conducted and radiated disturbances.

---Indoor equipment high-altitude electromagnetic pulse (HEMP) immunity (GB/T 17799.5). The purpose is to regulate the electrical and

HEMP immunity requirements for electronic equipment.

--- Immunity in the environment of power plants and substations (GB /Z 17799.6). The purpose is to regulate the generation, transmission and distribution of power systems

Immunity requirements for the equipment used and associated communication systems.

--- Part 7.Immunity requirements for equipment used to perform safety-related system functions (functional safety) in industrial locations (GB/T 17799.7).

The purpose is to determine the immunity test requirements related to continuous and transient, conducted and radiated disturbances of equipment including electrostatic discharge.

--- Part 8.Launch of special equipment in commercial and light industrial places (GB/T 17799.8). intended to provide for commercial and light

Emission test requirements for specialized equipment used in industrial locations.

This document focuses on the immunity test requirements related to continuous and transient, conducted and radiated disturbances of equipment including electrostatic discharge.

Applicable to electrical and electronic equipment intended to be used in safety-related systems, for the supplier to declare that the equipment used in safety-related systems is resistant to

It is used when the immunity of electromagnetic disturbance is used, and it is also used by designers, system integrators, installers and evaluators of safety-related systems when evaluating

Used in declarations made by suppliers and to provide guidance to product committees.

Safety) Immunity requirements for equipment

1 Scope

This document is used by suppliers when declaring the electromagnetic immunity of equipment used in safety-related systems.

Designers, system integrators, installers and evaluators of safety-related systems should also use this document to evaluate suppliers as

issued a statement. This document provides guidance for product committees.

This document applies to electrical and electronic equipment intended for use in safety-related systems, namely.

* meet the requirements of IEC 61508 and/or other domain-specific functional safety standards, and

* Operation in industrial locations as described in 3.1.15.

Note 1.The final safety-related system is designed by a system integrator (or equivalent staff), who is responsible for assessing the suitability of the device for a particular application. Should

See GB /Z 17624.2-2013 Appendix D for the process.

The purpose of this document is to determine the immunity test requirements for equipment related to continuous and transient, conducted and radiated disturbances including electrostatic discharge.

These requirements are only for functions intended for functional safety applications. For each port considered, test requirements are specified.

Note 2.However, the immunity requirements of this document do not include extreme situations, which can occur in any place, but the probability of occurrence is extremely low. Therefore, safe

It is the responsibility of the relevant system designer to check that the requirements of this document cover the electromagnetic phenomena in the intended application.
