NBN EN 60584-1:2014 (2013-12) THERMOCOUPLES PART 1: EMF SPECIFICATIONS AND TOLERANCES
 
Price Excl. VAT Total number of pages, tables and drawings
25.00 € 2 P..
Description
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.

ATTENTION: Belgian registered standards (NBN EN or NBN HD) are generally only available in English or French. Only the cover page is translated and the document itself is in English or in French.

Very important notice: 98% of the text of the NBN EN 55XXX, NBN EN 6XXXX comes from the IEC text which is NOT included. This text can be ordered here: IEC 60584-1:2013. For the series NBN EN 50XXX, the standards are however complete.
