This European Standard specifies requirements and testing for dial indicating thermometers using sensing methods of gas expansion (symbol GE), liquid expansion (symbol LE) and bimetallic strip (symbol BM). Nominal sizes are from 40 to 160, and temperature measurement from -100 oC to +700 oC.
Thermometers specified have circular scales, and are for industrial use only.
Thermometers of square form are also covered by this standard except for case, scale and pointer dimensions.
Annex A includes recommendations for selection and installation.
This standard does not apply to thermometers for medical use nor to thermometers with electrical limit contact devices.
