Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
The Standard is a modified ASTM E1751 use the translation method.2000 No letter code combination of temperature thermocouple thermal emf table
(Standardguidefortemperatureelectromotiveforce (EMF) tablesfornon-letterdesignatedthermo-
couplecombinations).
The standard in the development of the structure of the text made editorial changes.
This standard ASTME1751 technical differences are.
--- Remove the gold - platinum and platinum - palladium two kinds of thermocouples, the remaining 7 kinds of thermocouple was no difference in the technical characteristics of the original standard;
--- Added "2 Normative references" to "Appendix A" "Appendix B";
--- Rewrite "3 Terms and Definitions";
--- Deleted the original "4 Significance and Use" "8 keywords";
--- Original standard "3 Data Sources" "5 thermocouple type" "6 thermal emf - temperature tolerance initial value" of the content of this standard moved
Quasi "4 indexing table Information". Also delete the Fahrenheit indexing table indexing formulas and coefficients of each thermocouple. Detailed repair
Change the contents of Appendix B.
