ASTM E1751-00

Standard Guide for Temperature Electromotive Force (emf) Tables for Non-Letter Designated Thermocouple Combinations (Withdrawn 2009)

SCOPE
1.1 This guide consists of reference tables that give temperature-electromotive force (EMF) relationships for special purpose, limited use, thermocouple combinations that do not have a letter designation.  
1.2 Extension wire or compensating extension wires are not covered by this guide. ASTM MNL 12 or thermocouple alloy suppliers should be consulted.
WITHDRAWN RATIONALE
This guide consists of reference tables that give temperature-electromotive force (emf) relationships for special purpose, limited use, thermocouple combinations that do not have a letter designation.
Formerly under the jurisdiction of Committee E20 on Temperature Measurement, this guide was withdrawn in March 2009 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
