1.1This specification covers separable single-circuit miniature thermocouple connectors with two flat 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.

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

1.3The values stated in either SI units or inch-pound 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.

1.4The plug and jack may be ordered separately but many of the connector characteristics (see Table 1) are qualified as a mated pair. The requirements in this standard are applicable for the connector pair supplied by the same manufacturer.

1.5The 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.

1.6This 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.
