ASTM E1129/E1129M-15

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.

1.1 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.

1.4 The following precautionary statement pertains only to the test methods portion, Section 9, of this specification.
