Sr. NoTestsSpecification
1DescriptionColorless, transparent, oily liquid, free, or practically free, from fluorescence. Is odorless
and tasteless when cold, and develops not more than a faint odor of petroleum when heated
2SolubilityInsoluble in water and in alcohol; soluble in volatile oils. Miscible with most fixed oils, but
not with castor oil.
3 Identification : AIdentification
Identification : BIt meets the requirements in specific test for viscosity.
4Limit of polycyclic aromatic
hydrocarbons		The absorption at any wavelength in the specific range of the sample solution is NMT
one-third of the absorbance of the standard.
5 Specific gravity0.818 to 0.880
6 Viscosity3.0 – 34.4 mm / S- at 40° C
7 AcidityNMT 1.0 mL of 0.01 N sodium hydroxide is required to produce pink color
8Readily carbonisable substanceThe acid portion of sample solution does not become darker than the standard solution.
9Solid paraffins.The liquid is sufficiently clear that a black line, 0.5 mm in width, held vertically behind the
vessel is easily seen.
10Sulphur compoundNo dark brown color develops.
