IS 3506 : 1989 Tables for Alcoholometry (Pyknometer Method)

1 Scope

1.1 This standard covers two tables. Pyknometer tables give theapparent specific gravity or apparent relative density, tº/tº, measured in air using 50 mlcapacity pyknometer, that is, apparent mass of alcoholic liquid attºC/apparent mass of water at tºC,against the ethanolic content at 20ºC in thealcoholic liquid at 20ºC that is real strength20º/20º or volume percent ofethanol at 20ºC. Table 2 gives the minorcorrections for conversion of ethanolic real strength at 20ºC to that at 15ºC or 15.56ºC which may be required under the present Excise Rulesuntil the international system of real strength at 20ºC is adopted for excise purposes in our country.
