适用范围：2.1 Type of equipmentThis standard applies to fusion welded wrought aluminium and aluminium alloy enclosures pressurizedwith dry air, inert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases, used inindoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is usedThe enclosures comprise parts of electrical equipment not necessarily limited to the following examples:circuit-breakersswitch-disconnectorsdisconnectorsearthing switchescurrent transformersvoltage transformerssurge arrestorsbusbars and connectionsThe scope covers also pressurized components such as the centre-chamber of live tank switchgear andcontrolgear, gas-insulated current transformers, etc.2.2 ProductionThe production of the enclosures shall be in accordance with documented welding procedures which shallbe carried out by well trained and supervised welding personnel. Where International Standards(ISO or CEN) are not available National Standards may be used.NOTE This standard will be revised as soon as possible when ISO or CEN standards covering the various aspects are available.2.3 Quality assuranceIt is the intention of this standard that the switchgear manufacturer shall be responsible for achieving andmaintaining a consistent and adequate quality of product.Sufficient examinations shall be made by the enclosure manufacturer to ensure that the materials,production and testing comply in all respects with the requirements of this standard and ISO 6213:1983.Inspection by the user’s inspectors shall not absolve the switchgear manufacturer from his responsibilityto exercise such quality assurance procedures as to ensure that the requirements and the intent of thisstandard are satisfied.NOTE Reference should be made to the ISO 9000 series of standards for quality assurance systems.
