1.1This standard describes a thermal emf test method for base-metal thermocouple connectors including Types E, J, K, N and T. Standard connectors such as found in Specifications E1129/E1129M and E1684 as well as non-standard connector configurations and connector components can be evaluated using this method.

1.2The measured emf is reported as an equivalent temperature deviation or error relative to a reference thermocouple of the same type. This method can be used to verify deviations introduced by the connector greater than or equal to 1°C.

1.3The connector is tested with thermocouple contacts axially aligned with a temperature gradient using a specified thermal boundary condition. The actual temperature difference developed across the connector and corresponding error will depend on the connector design.

1.4Connector contacts are often fabricated from raw materials having temperature-emf relationships in accordance with Specification E230. However, verifying Specification E230 tolerances is not within the scope of this method.

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
