This standard was first published in 1968. The technical committee responsible for the prepara- tion of this standard felt the need to revise this standard to keep pace with IS0 standard on this subject. In this revision, the Table 1 Density of water has been suitably modified in addition to the density of air at 27°C and 760 mm Hg pressure. While density at a specified temperature is a fundamental molecular property of a given sub- stance, the product specification generally and for good reasons include relative density at a specified temperature say, 20°C/20”C or 27”C/27”C, etc, that is. density of substance at the specified temperature density of water at the specified temperature This is because the accuracy of the relative density is independent of the accuracy of the density bottle or pyknometer. The technical committee, the composition of which is given in Annex A, responsible for formula- tion of this Indian Standard is working on to incorporate a suitahle formula for evaluation of relative density at a specified temperature in a product specification when relative density is conveniently measured at ambient temperature. This standard is based on the IS0 758 ‘Method for determination of density of liquids at 20°C. In order to obtain uniformity of methods in Indian Standards and also international agreement on the methods where possible, the details of the method prescribed by IS0 have largely been left unchanged except at a few places where change is called for to suit Indian conditions. In reporting the result of a test or analysis made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it should be done in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values ( revised )‘. i IS 4730 : 1994 Indian Standard METHOD FOR DETERMINATION OF DENSITY OF LIQUIDS ( First Revision ) 1 SCOPE 6 PROCEDURE This standard prescribes a reference method for 6.1 Clean and dry the density bottle and weigh the determination of the density of liquids for it with its stopper to the nearest milligram. industrial use with an accuracy of 0.05 percent.
