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.
