Gives guidance on the selection and use of solid-stem and enclosed-scale thermometers in the temperature range -200°C to 1050°C.

This Section of BS 1041 gives guidance on the selection and use of: hermetically-sealed glass thermometers in which a thick-walled capillary stem is fused to a reservoir or bulb containing a thermometric liquid and the temperature scale is engraved or permanently marked on the stem; NOTE Thermometers of this type are commonly known as “solid-stem thermometers??. enclosed-scale liquid-in-glass thermometers, in which a comparatively thin-walled capillary together with a separate strip bearing the scale is enclosed in a hermetically-sealed glass sheath. Collectively, they span a temperature range from − 200 °C to 1 050 °C and are in some cases cap able of measurement uncertainties of ± 0.005 degrees Celsius (see 5.2). Generally, but not without exception, they fall within the scope of the following British Standards: BS 593 BS 692 BS 791 BS 1365 BS 1704 BS 1900 BS 5074 BS 2000-0:Addendum 1 NOTE 1 In this Section of BS 1041, temperatures below 0 °C are indicated with a minus sign; temperatures above 0 °C have no sign. NOTE 2 The titles of the publications referred to in this Section of BS 1041 are listed on the inside back cover.
