Three series of accurate laboratory thermometers of solid-stem, mercury-in-glass type, overall length about 400 mm; Series A and B are graduated in either Celsius or Fahrenheit for either total or partial immersion. Appendix gives procedure and recommended values for average emergent liquid column temperature for partial immersion thermometers.

This British Standard specifies requirements for series A, B and F laboratory thermometers (see foreword) calibrated either for total or for partial immersion, covering the overall temperature ranges − 30 °C to + 400 °C and − 23 °F to + 320 °F.

NOTE The titles of the publications referred to in this standard a relisted on the inside back cover.
