Thermocouples -- Part 2: Tolerances

Former HD 446.2 S2

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.

3) In order to promote international unification, the IEC expresses the wish that all National Committees should adopt the text of

recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter.

PREFACE

This standard has been prepared by Sub-Committee 65B: Elements of Systems, of I EC Technical

Committee No. 65: Industrial-process Measurement and Control.

couple reference tables for use in converting thermocouple voltages into their equivalent measured

temperatures, and vice versa. Part 2: Tolerances, contains manufacturing tolerances for thermocouples

manufactured in accordance with e.m.f.-temperature relationships of Pa rt 1 of the standard.

A first draft was discussed at the meeting held in Philadelphia in 1979. A revised draft, Document

65B(Central Office)23, was submitted to the National Committees for approval under the Six Months'

Rule in March 1980.

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

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
