    1、Designation: E1751/E1751M 15Standard Guide forTemperature Electromotive Force (emf) Tables for Non-Letter Designated Thermocouple Combinations1This standard is issued under the fixed designation E1751/E1751M; the number immediately following the designation indicates the yearof original adoption or,

    2、 in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide consists of reference tables that givetemperature-electromotive force

    3、 (emf) relationships for specialpurpose, limited use, thermocouple combinations that do nothave a letter designation.1.2 Extension wire or compensating extension wires are notcovered by this guide. ASTM MNL 122or thermocouple alloysuppliers should be consulted.1.3 The values stated in either SI unit

    4、s or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2. Referenced Documents2.1
