Fire hazard testing - Part 2-11: Glowing/hot-wire based test methods - Glow-wire flammability test method for end-products (GWEPT)(IEC 62271-201:2014)
This part of IEC 62271 specifies requirements for prefabricated solid-insulation enclosed
switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and
including 52 kV for indoor installation and for service frequencies up to and including 60 Hz.
Access to the switchgear and controlgear is restricted to authorized personnel.
NOTE 1 For the use of this document high-voltage (IEC 60050-601:1985, 601-01-27) is the rated voltage above
1 000 V. However, medium voltage (IEC 60050-601:1985, 601-01-28) is commonly used for distribution systems
with voltages above 1 kV and generally applied up to and including 52 kV; refer to [1] of Bibliography.
NOTE 2 Although primarily dedicated to three-phase systems, this standard can also be applied to single-phase
or two-phase systems.
Enclosures may include fixed and removable components and may be filled with fluid (liquid
or gas) to provide an extra insulation. For switchgear and controlgear containing gas-filled
compartments, the design pressure is limited to a maximum of 300 kPa (relative pressure).
Solid-insulation enclosed switchgear and controlgear complying with this standard can be
safely touched when energised.
Solid-insulation enclosed switchgear and controlgear for special use, for example, in
flammable atmospheres, in mines or on board ships, may be subject to additional
requirements.
Components contained in solid-insulation enclosed switchgear and controlgear are designed
and tested in accordance with their various relevant standards. This standard supplements
the standards for the individual components regarding their installation in switchgear and
controlgear assemblies.
This standard does not preclude that other equipment may be included in the same enclosure.
In such a case, any possible influence of that equipment on the switchgear and controlgear
should be taken into account.
NOTE 3 Switchgear and controlgear assemblies having a metal enclosure are covered by IEC 62271-200 refer to
[9] of Bibliography.
