(Main)Industrial platinum resistance thermometers and platinum temperature sensors
Industrial platinum resistance thermometers and platinum temperature sensors
IEC 60751:2008 specifies the requirements and temperature/resistance relationship for industrial platinum resistance temperature sensors later referred to as 'platinum resistors' or 'resistors' and industrial platinum resistance thermometers later referred to as 'thermometers' whose electrical resistance is a defined function of temperature. Values of temperature in this standard are in terms of the International Temperature Scale of 1990, ITS-90. Temperatures in degrees Celsius are denoted by the symbol t, except in Table 1 where the full nomenclature t90/°C is used. The standard covers resistors or thermometers for all or part of the temperature range 200 °C to +850 °C with different tolerance classes, which may cover restricted temperature ranges. This second edition cancels and replaces the first edition published in 1983, amendment 1 (1986) and amendment 2 (1995). It constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows: While the temperature/resistance relationship in 4.2 remains unchanged, there are several changes in the other chapters. Most important are: tolerance classes follow a new scheme; tolerance acceptance test is included; hysteresis test is included; several changes in the individual tests; appendices are deleted.
Industrielle Platin-Widerstandsthermometer und Platin-Temperatursensoren
Thermomètres à résistance de platine industriels et capteurs thermométriques en platine
La CEI 60751:2008 spécifie les exigences et la relation température/résistance pour les capteurs à résistance de platine industriels, dénommés ci-après 'résistances de platine' ou 'résistances', et les thermomètres à résistance de platine industriels, dénommés ci-après 'thermomètres', dont la résistance électrique est une fonction définie de la température. Les valeurs de température données dans la présente norme sont exprimées en accord avec l'Echelle Internationale de Température de 1990, EIT-90, en degrés Celsius, et par le symbole t, à l'exception du Tableau 1 où l'expression t90/°C est utilisée. Elle couvre les résistances ou thermomètres pour toutes les parties de la gamme -200 °C à +850 °C avec différentes classes de tolérance, qui peuvent couvrir des domaines de températures limités. Cette deuxième édition annule et remplace la première édition parue en 1983, l'amendement1 (1986) et l'amendement 2 (1995). Cette édition constitue une révision technique. Par rapport à l'édition précédente, les modifications techniques majeures sont les suivantes: Alors que la relation entre la température et la résistance, donnée en 4.2 est inchangée, plusieurs modifications sont apportées dans les autres chapitres. Les plus importants sont: les classes de tolérance suivent un nouveau système; un essai d'acceptation de la tolérance est inclus; un essai d'hystérésis est inclus; plusieurs modifications sont apportées dans les essais individuels; des appendices sont supprimés.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC Na
