1.1 This standard specifies the metrological and technical requirements for clinical electrical thermometers for continuous measurement of human or animal body temperature. Such instruments are normally used to monitor the temperature at appropriate body sites of a patient undergoing certain surgical procedures or during intensive care. 1.2 The measuring range of clinical temperature covered shall be a minimum of 35.5oC to 42.0oC, which is consistent with the range specified by Gulf Standard No GSO OIML R115: 2002 “Clinical thermometers, mercury-in-glass with maximum device”, 1.3 This standard applies to battery-or mains-powered instruments. 1.4 The instruments may be equipped to accommodate secondary indicators, printing devices, and other auxiliary devices. The metrological requirements for such accessories are not covered by this standard. 1.5 Clinical electrical thermometers designed to measure skin temperature are not covered by this standard “Clinical electrical thermometers with maximum device” are covered by GSO OIML R115 : 2002. 1.6 This standard does not exclude the use of any contact device based on other measurement principles that meets equivalent performance standards in continuously measuring temperature.
