This part of IEC 141 applies to tests on radial field, oil-filled, paper-insulated metal-sheathed cables and their accessories, which operate with a minimum static pressure of between 20 kPa (0,2 bar) and 300 kPa (3,0 bar) inclusive, a maximum static pressure of not more than 800 kPa (8,0 bar) and a minimum transient pressure of not less than 20 kPa (0,2 bar). (The quoted pressures are above atmospheric pressure.) This part is applicable also to cables and accessories with maximum static pressures exceeding 800 kPa (8,0 bar), except that clauses 3.2, 4.5 and 5.2 may be appropriately modified by agreement between the purchaser and the manufacturer. The tests are applicable to cables and accessories intended to be used in systems with nominal voltages not exceeding 400 kV between phases. For cables manufactured in long lengths, the application of this part is subject to agreement between the purchaser and the manufacturer.
