CEN/TC 205/WG 12 - Clinical thermometers

This Part of EN 12470 specifies performance requirements and test methods for phase change-type (dot matrix) thermometers for measuring temperature in body cavities.
NOTE   A body cavity can be the mouth, rectum or armpit.
This European Standard does not apply to clinical thermometers designed for special applications (e.g. thermometers for hypothermia) which owing to their measurement range, scale interval or maximum permissible error do not meet the requirements specified in this Standard.

This Part of EN 12470 specifies performance requirements and test methods for clinical liquid-in-glass thermometers with maximum device and applies only to thermometers filled with metallic liquid.
NOTE 1   Note that in some European countries the use of mercury is prohibited in clinical thermometers.   
NOTE 2   Substances other than metallic liquids can be used in the manufacturing of liquid-in-glass thermometers. No reference is made to these in this European standard because there is no experience of clinical thermometers which use other substances.
This European Standard does not apply to clinical thermometers designed for special applications (e.g. thermometers for premature babies, ovulation thermometers) which, owing to their measurement range, scale interval or maximum permissible error, fall outside the scope of this standard.

This part of EN 12470 specifies the metrological and technical requirements for electrical thermometers for continuous measurements.
This European Standard applies to devices that are operated by an electrical power supply either by mains or internal power sources.
The devices can be equipped to accommodate secondary indicators, printing devices, and other auxiliary devices. The metrological requirements for such accessories are not covered by this European Standard.
Thermometers intended to measure skin temperatures are not covered by this European Standard.
This European Standard does not intend to exclude the use 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. 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.

This Part of EN 12470 specifies the performance requirements for compact clinical electrical thermometers with maximum device (non-predictive and predictive).
This European Standard applies to devices that, when taking temperatures, are powered by an internal power supply and that provide a digital indication of temperature.
This European Standard does not apply to clinical electrical thermometers for continuous measurement and thermometers intended to measure skin temperature.

This Part of EN 12470 specifies the metrological and technical requirements for clinical infra-red (IR) ear thermometers with maximum device for intermittent determination of human body temperature.
This European Standard applies to devices that when taking temperatures are powered by a power supply either internal or by mains and that provide an indication of the subject's body temperature through measurement of thermal radiation from all or part of the ear canal.
NOTE:   Devices designed to measure tympanic membrane temperature only are also covered by this standard.
