1.1 ,This specification establishes dimensional and material requirements for compacted, mineral-insulated, metal-sheathed (MIMS), Type S (platinum-10 ,% rhodium versus platinum), Type R (platinum-13 ,% rhodium versus platinum), and Type B (platinum-30 ,% rhodium versus platinum-6 ,% rhodium) noble metal thermocouples. This specification also establishes dimensional recommendations and material requirements for compacted MIMS cable with at least one noble metal thermoelement pair.
