AS 2113.1-1998 (R2013) pdf free.Oil of Australian eucalyptus – Part1:70 to 75% cineole.
This specification lays down certain characteristics of oil of eucalyptus produced in Australia and containing 70 to 75 percent cineole.
3 DEFINITIONS For the purpose of this Standard, the definitions below apply.
3.1 Oil of Australian eucalyptus—the oil obtained by the steam distillation from foliage and branchiets of any suitable species of eucalyptus provided that the oil conforms with the remainder of this specification. The oil may be rectified if necessary.
3.2 Laboratory sample—a sample as prepared for sending to the laboratory for inspection and testing and being representative of the bulk.
4 CHARACTERISTICS
4.1 Preparation of laboratory sample The minimum volume of oil required as laboratory sample shall be 50 mL, collected in accordance with ISO 356.
4.2 General description A clear, colourless to pale yellow, mobile liquid at 20°C with the characteristic odour of 1,8-cineole.
4.3 Relative density at 20°C/20°C When determined in accordance with Iso 279, the ratio of the mass of a given volume of the oil to that of an equal volume of distilled water shall be in the following range:
(a) Minimum: 0.906.
(b) Maximum: 0.926.
4.4 Refractive index When measured in accordance with ISO 280 at a wavelength of
589.3 ±0.3 nm (corresponding to the D line of the sodium spectrum), the refractive index
of the oil at 20°C shall be in the following range:
(a) Minimum: 1.458.
(b) Maximum: 1.470.
4.5 Optical rotation When determined in accordance with ISO 592, the optical rotation of the oil at 20°C using light of wavelength 589.3 ±0.3 nrn (corresponding with the D line of the sodium spectrum) shall be in the range _5.00 to +10.00.
4.6 Miscibility in ethanol When tested in accordance with ISO 875, one volume of oil shall not require more than five volumes of ethanol (700 mL/L) at 20°C to give a clear solution.
