Background The CTL decided in 2014 to convert the CTL OPERATIONAL Procedure (OP) into the IECEE . OPERATIONAL DOCUMENT (OD) structure. The content of the former OP's has not been changed. Editorial adjustments have been made where necessary. The forms have been separated into independent documents for better handling. A transfer table which CTL/OP has been transferred into which OD is given in OD 5000.

7 1 Purpose This Laboratory Procedure establishes procedures for acceptance of thermocouple wire and establishes procedures for preparation, attachment, extension and use of thermocouples for temperature measurement. 2 Scope This procedure applies to acceptance of thermocouple wire used for temperature measurement in conjunction with testing of electrical and similar products. It applies to thermocouples for temperature measurement used for testing of electrical and similar products. It also describes recommended practices shown by experience to be useful.

8 This Procedure does not prohibit use of other practices that may also be valid and useful. 3 Normative References The following publication contain provisions which, through reference in this text, constitute modification or additions of this OPERATIONAL DOCUMENT . IEC 60584 Series Thermocouples UKAS LAB 11 Traceability of Temperature Measurement ANSI MC96-1 Temperature Measurement Thermocouples 4 Definitions For the purpose of this publication, the definitions of IECEE Definitions apply with the following additions: None 5 Abbreviations None 6 Responsibility Laboratories must ensure that the thermocouple wire purchased is of acceptable accuracy.

9 Laboratory personnel assigned to acceptance of shipments of thermocouple wire are responsible to follow the procedure for acceptance of thermocouple wire. The type of thermocouples utilized must be used within the manufactured specified operating parameters for that type of thermocouple . Note: Typically, Types J, K and T tolerance class 1 thermocouples are used for CB Scheme testing. Laboratory personnel who prepare and use thermocouples are responsible to follow the procedure for preparation, extension and use of Thermocouples.

10 IECEE OD-5012:2015 IEC 2015 4 . 7 Procedure for acceptance of thermocouple wire When ordering thermocouple wire, the thermocouple class or special limits requirements shall be specified when placing the purchase order. The supplier of the wire shall be required to provide a certificate of compliance with the specification. The certificate of compliance shall include the results of the pre- shipment testing used to establish conformance. As a minimum, the testing shall include one thermocouple taken from the reel of thermocouple wire.
