Foreword
This standard replaces GB/T 2614-1998 "nickel-chromium - nickel silicon thermocouple wire."
The main difference between this standard and GB/T 2614-1998 compared as follows.
--- Thermal EMF reference ASTM E230-2003 tolerance requirements, and the original standard thermal electromotive force tolerance is used
IEC 584-2.1995 requirements.
--- For ease of use, it is listed in Appendix C of the standard nickel-chromium - nickel aluminum thermocouple wire unipolar platinum thermal electromotive force, in order to facilitate reference.
--- The standard according to GB/T 1.1-2000 and GB/T 20000.3-2003 standard requirements of the original were edited text on
modify.
