IEC 60840:2020 specifies test methods and requirements for power cable systems, cables alone and accessories alone, for fixed installations and for rated voltages above 30 kV (Um = 36 kV) up to and including 150 kV (Um = 170 kV). The requirements apply to single-core cables and to individually screened three-core cables and to their accessories for usual conditions of installation and operation,…

This document specifies two methods for the determination of the neutralizing value (NV) of liming materials. Method A is applicable to all liming materials except silicate liming materials. NOTE 1 Examples of hard liming materials are limestone and dolomite. Examples of soft liming materials are chalk, marl and burnt lime. Method B is applicable to all liming materials. Neither method…

IEC 60667-2:2020 gives methods of test for vulcanized fibre sheets for electrical purposes. Material made by combining with an adhesive several thicknesses of vulcanized fibre is not covered by this document. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application is based on the actual…

1.1 This document establishes a system of designation for plasticized PVC thermoplastic material which can be used as the basis for specifications. 1.2 The types of PVC-U plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) Shore hardness, b) density, c) torsional-stiffness temperature at 300 MPa, and on…
