| 1 | A general purpose maximum and minimum thermometer is used in educational institutions, industries, offices, green houses, etc., for registering extremes of temperature during a given period, usually 24 hours. It also acts as two thermometers each roughly indicating the dry bulb temperature of the ambient air. For more accurate work, however, use is made of two separate thermometers, that is, one indicating the maximum temperature and the other the minimum temperature during a given period (see IS 5681 ‘General meteorological thermometers, Liquid-In-Glass - Specification (second revision)’). | |
| 2 | This standard was originally published in 1973. 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. 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. | |
