BS 1365:1990

Two series of mercury-in-glass thermometers for either total immersion or partial immersion. Series A comprises 7 thermometers, scale range approximately 60°C, scale interval 0.5°C covering range -10°C to +360°C. Series B comprises 24 thermometers, scale range approximately 10°C, scale interval 0.1°C covering range -10°C to +220°C.

This British Standard specifies requirements for two series, A and B, of mercury-in-glass thermometers. In each series, thermometers calibrated for total immersion, i.e. immersion to the reading (designated A1 or B1) and thermometers calibrated for partial immersion (designated A2 or B2) are included for each temperature range.

Series A1 comprises seven total immersion thermometers, each with a scale span of approximately 60 Celsius degrees, covering the range − 10 °C to + 360 °C.

Series A2 covers the same range for an immersion of 80 mm.

Series B1 comprises 24 total immersion thermometers, each with a scale span of approximately 10 Celsius degrees, covering the range − 10 °C to + 220 °C.

Series B2 covers the same range for an immersion of 70 mm.
