In ISOMIL-T the thermoelectric voltages of the thermocouples are in accordance with the basic standard values within the usual tolerance range. For NiCr-Ni the basic values of the thermoelectric voltage are identical in the German and international standards. For both Fe-CuNi (Thermoiron-Thermoconstantan) and Cu-CuNi (Thermocopper-Thermoconstantan) they differ.
These thermocouples are available in ISOMIL-T in accordance with the German Standard Norm DIN 43710 and with the International Thermoelectric Voltage Series (IEC 584).
The limit deviation of the thermocouple voltage is available according the following norm:
• DIN IEC 584-2
• ASTM E 230-93 / ANSI.MC.96.1
Other norms, e.g. GOST on request.
