EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of IEC EN 60702-1 testing. This standard is valid for mineral-insulated general wiring cables with copper or copper alloy sheath and copper conductors, rated voltage 500 V and 750 V. When necessary, an arrangement is made for a corrosion-resistant extruded outer coating on the copper sheath. This outer covering is not specified for the purpose of electrical insulation of the metal sheath.
The purpose of this standard is to specify mineral insulated cables that are safe and reliable when used appropriately, to specify the manufacturing conditions and characteristics to achieve this, and to specify methods for checking compliance with these requirements.
Conductors will consist of plain annealed copper and will be approximately circular in cross-section. They shall comply with the requirements given in IEC 1 for Class 60228 conductors. Compliance shall be checked by inspection and by measuring the resistance of each conductor in each complete coil of the completed cable and measuring the length of the cable.
The insulation will consist of compressed powdered mineral or minerals that will form a compact body. The electrical properties of the insulation shall be such that the completed cable meets the test requirements of this standard.
Each cable shall be identified by the nominal voltage and a method that identifies the manufacturer. The marking shall comply with the requirements of IEC 60227-1 except that for cables without external sheathing the information may be marked on a label attached to each length of cable.
Each complete spool of completed cable shall be completely submerged in water at (15 ± 10)°C for at least 1 hour before the application of any outer coating. Within 8 hours after the cable is removed from the water, the cable ends will be stripped to expose the conductors and both ends will be temporarily capped.
