STANDARD ITS-90 THERMOCOUPLE TABLES

The Instrument Society of America (ISA) has assigned standard letter designations to a number of thermocouple types having specified emf-temperature relations. These designations and the approximate metal compositions that meet the required relations, as well as the useful temperature ranges, are given below.

TABLE 1. Designation and Composition of Various Metals Used in Thermocouples

Type	Composition	t
Type B	(Pt + 30% Rh) vs. (Pt + 6% Rh)	0 to 1820 °C
Type E	(Ni + 10% Cr) vs. (Cu + 43% Ni)	–270 to 1000 °C
Type J	Fe vs. (Cu + 43% Ni)	–210 to 1200 °C
Type K	(Ni + 10% Cr) vs. (Ni + 2% Al + 2% Mn + 1% Si)	–270 to 1372 °C
Type N	(Ni + 14% Cr + 1.5% Si) vs. (Ni + 4.5% Si + 0.1% Mg)	–270 to 1300 °C
Type R	(Pt + 13% Rh) vs. Pt	–50 to 1768 °C
Type S	(Pt + 10% Rh) vs. Pt	–50 to 1768 °C
Type T	Cu vs. (Cu + 43% Ni)	–270 to 400 °C

The compositions are given in weight percent, and the positive leg is listed first. It should be emphasized that the standard letter designations do not imply a precise composition but rather that the specified emf-temperature relation is satisfied.

Tables 2, 4, 6, 8, 10, 12, 14, and 16 contain, for each thermocouple type, the emf as a function of temperature on the International Temperature Scale of 1990 (ITS-90). The left-most column has temperature t at 100 °C intervals. Columns to the right have temperatures at t ± n °C intervals where n = 10, 20, 30, etc., as indicated in the column heading. The values in these tables were calculated using the following equation.

E = c₀ + c₁t + c₂t² + c₃t³ + … c_ntⁿ

where E is the emf in millivolts, t is the temperature in degrees Celsius (ITS-90), and c₀, c₁, c₂, c₃, etc., are the coefficients, which have been extracted from Ref. 1. For Type K thermocouples, an additional term in the equation is required as discussed in the Note. The coefficients in the equation used to generate the tables are also given in Tables 3, 5, 7, 9, 11, 13, 15, and 17, respectively.

Tables 18-25 give the inverse relationships, i.e., the coefficients in the polynomial equation that expresses the temperature as a function of thermocouple emf. The accuracy of these equations is also stated.

Further details and tables at closer intervals may be found in Ref. 1.

NOTE—In the 0 °C to 1372 °C range, there is also an exponential term that must be evaluated and added to the equation. The exponential term is of the form c₀e^c₁^{(t–126.9686)}², where t is the temperature in °C, e is the natural logarithm base, and c₀ and c₁ are the coefficients. These coefficients are extracted from Ref. 1.
