| 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 first published in 1977. And in this first revision, Kerosene oil as a thermometric liquid has been added. A sampling plan for lot testing has also been prescribed and several editorial changes such as the inclusion of the Reference clause, Hindi Title, ICS no, BIS certification marking clause, etc. have also been incorporated. | |
