This specification covers the classification, testing, and corresponding requirements for negative-temperature-coefficient thermistor-type sensors intended to be used for clinical laboratory temperature measurements or control, or both, within a specified range. This specification also covers the detailed requirements for ASTM designated sensors.

1.1 This specification covers the general requirements for Negative Temperature Coefficient (NTC) thermistor-type sensors intended to be used for laboratory temperature measurements or control, or both, within the range from −10 to 105°C.

1.2 This specification also covers the detailed requirements for ASTM designated sensors.

1.3 This specification also covers the requirements for general purpose, Negative Temperature Coefficient (NTC) thermistor-type sensors intended for use with Digital Contact Thermometers (also known as Digital Thermometers) within the range from –50 to +150°C.

1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
