Foreword
This Part is identical to the International Standard IEC 61000-6-2.1999 “Electromagnetic compatibility (EMC) - Part 6-2.Generic standards - Immunity for industrial environments”.
This Part specifies the immunity test items, grades (standard values), methods and performance criteria for electrical and electronic apparatus operating in industrial environments. If the above-mentioned apparatus already has product or product-family immunity test standards, these standards shall be used in preference.
This Part is Part 2 of “Electromagnetic compatibility - Generic standards”. “Electromagnetic compatibility - Generic standards” currently consists of the following parts.
GB/T 17799.1-1999 Electromagnetic compatibility - Generic standards -
Immunity for residential, commercial and light-industrial environments
GB/T 17799.2-2003 Electromagnetic compatibility - Generic standards -
Immunity for industrial environments
GB 17799.3-2001 Electromagnetic compatibility - Generic standards -
Emission standard for residential, commercial and light-industrial
environments
GB 17799.4-2001 Electromagnetic compatibility - Generic standards -
Emission standard for industrial environments
This Part was proposed by Electric Power Department of State Economic and Trade Commission.
This Part shall be under the jurisdiction of National Technical Committee on Electromagnetic Compatibility of Standardization Administration of China (CSBTS/TC 246).
Drafting organization of this Part. Wuhan High Voltage Research Institute of State Power Corporation.

Electromagnetic compatibility - Generic standards -
Immunity for industrial environments
1 Scope and object
This Part applies to electrical and electronic apparatus intended for use in industrial environments, for which no dedicated product or product-family immunity standard exists.
The frequency range of this Part is 0 Hz to 400 GHz. No tests need to be performed at frequencies where no requirements are specified.
Where a relevant dedicated product or product-family electromagnetic
compatibility (EMC) immunity standard exists, it will take precedence over all aspects of this generic standard.
The environments encompassed by this Part are industrial, both indoor and outdoor. Apparatus covered by this Part is intended to be connected to a power network supplied from a high or medium voltage transformer dedicated to the supply of an installation feeding manufacturing or similar plant, and intended to operate in or in proximity to industrial locations.
Apparatus intended to be used in industrial locations a e characterized by the existence of one or more of the following.
- a power network exists powered by a high or medium voltage power
transformer dedicated for the supply of an installation feeding
manufacturing or similar plant;
- industrial, scientific and medical (ISM)1) apparatus.
- heavy inductive or capacitive loads are frequently switched;
- currents and associated magnetic fields are high.
The object of this Part is to define immunity test requirements for apparatus defined in the scope in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges.
The immunity requirements have been selected to ensure an adequate level of 1) As defined in GB 4824, ISM class A.
immunity for apparatus at industrial locations. The levels do not, however, cover extreme cases, which may occur at any location, but with an extremely low probability of occurrence. Not all disturbance phenomena have been included for testing purposes in this Part, but only those considered as relevant for the equipment covered by this Part.
In this Part, test requirements are specified for each port considered. NOTE 1.Safety considerations are not covered by this Part.
NOTE 2.In special cases, situations will arise where the level of disturbances may exceed the levels specified in this Part, e.g. where an apparatus is installed in proximity to ISM equipment as defined in GB 4824 or where a hand-held transmitter is used in close proximity to an apparatus. In these Instances, special mitigation measures may have to be employed. NOTE 3.The industrial environment may be changed by special mitigation measures. Where such measures can be shown to produce an electromagnetic environment equivalent to the residential, commercial or light-industrial environment then the generic standard for this environment. or the relevant product standard, should be applied.
