EN 60584-1:2013

Thermocouples - Part 1: EMF specifications and tolerances

IEC 60584-1:2013 specifies reference functions and tolerances for letter-designated thermocouples (Types R, S, B, J, T, E, K, N, C and A). Temperatures are expressed in degrees Celsius based on the International Temperature Scale of 1990, ITS-90 (symbol t90), and the EMF (symbol E) is in microvolts. The reference functions are polynomials which express the EMF, E in V, as a function of temperature t90 in °C with the thermocouple reference junctions at 0 °C. Values of EMF at intervals of 1 °C are tabulated in Annex A. This third edition cancels and replaces the second edition published in 1995 and constitutes a technical revision. It includes the following changes: - IEC 60584-1:1995 and IEC 60584-2:1982 have been merged; - the standard is now explicitly based on the reference polynomials which express thermocouple EMF as functions of temperature. The tables derived from the polynomials are given in Annex A; - inverse polynomials expressing temperature as functions of EMF are given in Annex B, but inverse tables are not given; - the range of the polynomial relating the EMF of Type K thermocouples is restricted to 1 300 °C; - values of the Seebeck coefficients are given at intervals of 10 °C; - thermoelectric data (EMF and Seebeck coefficients) are given at the fixed points of the ITS-90; - some guidance is given in Annex C regarding the upper temperature limits and environmental conditions of use for each thermocouple type.

Couples thermoélectriques - Partie 1: Spécifications et tolérances en matière de FEM

La CEI 60584-1:2013 spécifie les fonctions de référence et les tolérances associées aux couples thermoélectriques désignés par une lettre (Types R, S, B, J, T, E, K, N, C et A). Les températures y sont exprimées en degrés Celsius selon l'Échelle Internationale de Température de 1990, EIT-90 (symbole t90) et les FEM (symbole E), en microvolts. Les fonctions de référence sont des polynômes qui expriment la FEM, E en V, en fonction de la température t90 en °C, les jonctions de référence des couples thermoélectriques étant placées à 0 °C. L'Annexe A présente, sous forme de tableau, les valeurs de la FEM tous les 1 °C. Cette troisième édition annule et remplace la deuxième édition parue en 1995. Elle constitue une révision technique. Elle inclut les modifications suivantes: - les CEI 60584-1:1995 et CEI 60584-2:1982 ont été fusionnées; - la norme repose désormais de manière explicite sur les polynômes de référence qui expriment la FEM des couples thermoélectriques en fonction de la température. L'Annexe A donne les tables dérivées des polynômes; - l'Annexe B donne les polynômes inverses, qui expriment la température en fonction de la FEM, mais ne donne pas les tables inverses; - le domaine de température du polynôme exprimant la FEM des couples thermoélectriques de Type K est limité à 1 300 °C; - la valeur du coefficient de Seebeck est donnée tous les 10 °C; - les données thermoélectriques (FEM et coefficients de Seebeck) sont fournies aux points fixes de l'EIT-90; - l'Annexe C donne des lignes directrices concernant les limites supérieures de température et les conditions d'environnement lors de l'utilisation de chaque Type de couple thermoélectrique.

Termočleni - 1. del: Specifikacije potencialov (EMF) in tolerance (IEC 60584-1:2013)

Ta del standarda IEC 60584 določa referenčne funkcije in tolerance za termočlene, označene s črkami (tipi R, S, B, J, T, E, K, N, C in A). Temperature so navedene v stopinjah Celzija na podlagi mednarodne temperaturne lestvice iz leta 1990, ITS-90 (simbol t90), EMF (simbol E) pa je naveden v mikrovoltih. Referenčne funkcije so polinomi, ki izražajo EMF, E in μV kot funkcijo temperature t90 v °C z referenčnimi spoji termočlenov pri 0 °C. Vrednosti EMF na enostopinjskih intervalih so tabelirane v Dodatku A. Za pomoč pri računanju temperatur so v Dodatku B podane inverzne funkcije, ki izražajo temperaturo kot funkcijo EMF znotraj podanih mej. Ta mednarodni standard določa tolerance termočlenov, ki so proizvedeni v skladu s tem standardom. Vrednosti toleranc veljajo za termočlene, proizvedene iz žic, običajno s premerom v razponu od 0,13 mm do 3,2 mm, pri čemer se upošteva, da je med uporabo instrument pravilno kalibriran. Dodatek C podaja smernice za izbiro termočlenov glede na temperaturno območje in okoljske pogoje.
