This International Standard specifies requirements for enclosed-scale adjustable-range thermometers for measuring small temperature differences not exceeding 5 C (or, exceptionally, 6 °C) within the range - 20 °C to + 140 °C. The thermometers are unsuitable for measuring absolute temperatures unless they have been compared with standard instruments immediately before use.
