BS EN 50068:2018 applies to wrought steel enclosures and their welding. These enclosures are pressurized with dry air, inert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases, used in indoor and outdoor installations of high-voltage switchgear and controlgear with rated voltages above 1kV, where the gas is used principally for its dielectric and/or arc-quenching properties.Cross References:EN ISO 17636EN ISO 17640EN ISO 3452EN 13445-3EN ISO 15614-1EN ISO 9712ISO 17636ISO 3452ISO 9606-1ISO 15614-1ISO 9712EN ISO 9606-1ISO 17640EN ISO 898-1:2013IEC 62271-1:2017EN 13445-2:2014EN ISO 898-2:2012ISO 898-2:2012EN 62271-1:2017ISO 898-1:2013EN 62271-203:2012EN 10028-7EN 10217-4EN ISO 6520EN 10028-2EN 12074EN ISO 9000EN 10028-6EN 10216-4EN 10273EN 10028-5EN 10269EN 10217-6EN 10291EN 10204EN 1092-1EN 10222-3EN 10028-3EN 10217-3EN 10222-4EN 10216-3EN 10028-4All current amendments available at time of purchase are included with the purchase of this document.
