This International Standard establishes the requirements for mineral insulated thermocouple cables and for mineral insulated thermocouples but does not specify cold end seals, terminations, connections and other accessories. This standard deals only with cables and thermocouples having one pair of base-metal conductors and is intended for use in general industrial applications. NOTES 1 This standard does not deal with precious metal cables and thermocouples. 2 Mineral insulated cables and thermocouples also are available with more than one pair of conductors or where there is one conductor and a sheath. In these cases the detailed prescriptions in this standard — e.g. the dimensions — may not necessarily apply. 3 The special requirements for nuclear primary loop applications are dealt with in other standards.
