Anotace

This specification covers the requirements for bare solid conductors made of tungsten and rhenium alloy thermoelements supplied in matched pairs. These thermoelements shall be suitable for use in either bead-insulated, bare-wire thermocouples, or in compacted metal-sheathed, ceramic insulated thermocouple material or assemblies. Unless otherwise noted, all information in this specification applies to both thermocouple combinations of tungsten-3 % rhenium versus tungsten-25 % rhenium (W3Re/W25Re) and tungsten-5 % rhenium versus tungsten-26 % rhenium (W5Re/W26Re; Type C). Thermoelements should meet specified physical, mechanical, thermoelectric, and compositional requirements.
