1 Psychrometers, which are also known as dry and wet bulb hygrometers and curometers, unventilated, are used for measuring atmospheric humidity (relative humidity) for agricultural, commercial and industrial purposes. They consist of two similar liquid-in-glass thermometers exposed side by side, the bulb of one of which is covered with a piece of wet fabric and allowed to cool by natural free evaporation. Relative humidity is computed from the readings of these two thermometers by the use of psychrometric tables.
2 This standard was originally published in 1970. The first revision of this standard is undertaken in view of the technological advancements taking place in the industry. Several editorial changes such as the inclusion of ICS No., Hindi Title, Reference Clause, and statuary changes such as the BIS Certification Marking clause as per the BIS Act 2016 have also been incorporated.
