Clinical thermometers - Performance of electrical thermometers for continuous measurement
1 Scope
This standard specifies the performance requirements for electrical thermometers for continuous measurements.
This standard is applicable to devices that are operated by an electrical power supply either by mains or internal power sources.
The devices can be equipped to accommodate indicators, printing devices, and other auxiliary devices. The requirements for such accessories are not covered by this standard.
Thermometers intended to measure skin temperatures are not covered by this standard.
This standard does not intend to exclude the applicability of any device based on other measuring principles that provides an equivalent performance in continuously measuring body temperature.
Note: Devices can have functions which are covered by different parts of EN 12470 (see Annex A). In this case, it is the responsibility of the manufacturer to indicate by which part of EN 12470 the function is covered, e.g. electrical thermometer with maximum device and exchangeable temperature probes.
