Thermocouples -- Part 2: Tolerances
Contains the manufacturing tolerances for both noble and base metal thermocouples manufactured in accordance with e.m.f. temperature relationships of Part 1 of the standard. The tolerance values are for a thermocouple manufactured from wires normally in the diameter range 0.25 mm to 3 mm, as delivered to the user and do not allow for calibration draft during use.
Thermopaare -- Teil 2: Grenzabweichungen der Thermospannungen
Couples thermoélectriques -- Partie 2: Tolérances
Contient les tolérances de fabrication pour les couples thermoélectriques de métaux précieux et de métaux communs fabriqués conformément aux tables de référence f.é.m. - températures de la première partie de la norme. Les valeurs des tolérances correspondent à celles des couples thermoélectriques fabriqués à partir de fils dont les diamètres sont normalement compris entre 0,25 mm et 3 mm tels qu'ils sont livrés à l'utilisateur. Les valeurs n'indiquent pas la dérive de l'étalonnage en cours d'utilisation.

THERMOCOUPLES
Part 2: Tolerances
1. Scope
This standard contains the manufacturing tolerances for both noble and base metal thermo-
couples manufactured in accordance with e.m.f.-temperature relationships of Pa rt 1 of the stan-
dard. The tolerance values are for a thermocouple manufactured from wires, normally in the
diameter range 0.25 mm to 3 mm, as delivered to the user and do not allow for calibration d rift
during use.
2. Definitions
2.1 Thermoelectric (Seebeck) effect
The thermoelectric effect is the production of an electromotive force (e.m.f.) due to the difference
of temperature between two junctions of different metals or alloys forming pa rt of the same
circuit.
2.2 Thermocouple
rt
A thermocouple is a pair of conductors of dissimilar materials joined at one end and forming pa
of an arrangement using the thermoelectric effect for temperature measurement.
2.3 Measuring junction
The measuring junction is that junction referred to in Sub-clause 2.2 which is subjected to the
temperature to be measured.
2.4 Reference junction
The reference junction is that junction of the thermocouple which is at a known (reference)
temperature to which the measuring temperature is compared.
2.5 Tolerance
The tolerance of a thermocouple is a specified maximum deviation in degrees Celsius from the
e.m.f -temperature va
