Essential oils — Determination of optical Rotation
2017
Document Number: NL ISO 592 : 2017
Sector: Chemical Technology
TC: NL TC 54
ICS: 71.100.60
This International Standard specifies a method for determining the optical rotation of essential oils. When dealing with solid oils, partially solid oils, oils that are highly viscous at room temperature, or highly coloured oils, this determination is carried out on a solution of the oil.
