    This specification covers separable single-circuit thermocouple connectors with two round pins. The widespread use of thermocouple connectors requires standardization of mating dimensions and performance characteristics. Connectors shall be constructed as either plugs or jacks, and these two forms shall be designed to connect with each other. Contact resistance test, thermal gradient test, and insulation resistance test shall be performed to meet the requirements prescribed.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    Significance and Use

    4.1 The widespread use of thermocouple connectors requires standardization of mating dimensions and performance characteristics.

    4.2 This specification describes standardized thermocouple connector dimensions and capabilities and includes test procedures suitable for evaluating the performance of a particular specimen or design. The tests described are not intended for routine inspection or rapid testing of large groups of connectors or for quality control purposes.

    1. Scope

    1.1 This specification covers separable single-circuit thermocouple connectors with two round pins. Connectors covered by this specification must be rated for continuous use to at least 300 °F (150 °C), but they may optionally be rated to a higher temperature.

    1.2 This specification does not cover multiple-circuit connectors, multi-pin connectors, miniature connectors, or connectors intended primarily for panel mounting. High temperature connectors (for example, those designed for continuous use at temperatures above approximately 500 °F (260 °C)) are not intended to be covered by this specification.

    1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in brackets are not conversions to the values they succeed and therefore shall be used independently of the preceding values. The values given in parentheses are conversions of the values they succeed. Combining values from the two systems may result in non-conformance with the standard.

    1.4 The following precautionary statement pertains only to the test methods portion, Section 9, of this specification. This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
