| Sl.No. | Synosis Points | |
| 1 | Adjustable range thermometers can be used over a wide range of temperatures in several industrial, agricultural and scientific applications where the variations around a ‘datum temperature’ do not exceed a span of 6°C, and where precise measurement of variations in temperature is involved. Such thermometers can be used with advantage in studies of chemical micro-reactions, combustion phenomena, fuel evaluation, germination of seeds, storage of cereals, micro-calorimetry, etc. | |
| 2 | This standard was originally published in 1977. . In relation to the Minamata Convention where mercury shall be removed from products by 2025, the committee responsible for formulating this standard decided to revise the standard by providing alternative thermometric liquids in addition to the mercury as liquid-in-glass thermometers are still in use in the country. | |
| 3 | In this first revision, Kerosene oil has been added as an alternative thermometric liquid. Several editorial changes such as the inclusion of the Reference clause, Hindi Title, ICS no, BIS certification marking clause, etc. have also been incorporated. | |
