BS 1041-2.1:1985

This standard BS 1041-2.1:1985 Code for temperature measurement. Expansion thermometers is classified in these ICS categories:

• 17.200.20 Temperature-measuring instruments

This Section of BS 1041 gives guidance on the selection and use of:

1. 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”.

2. 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.

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