In addition there is also a classification of ISO quality grade palm oil based on recommendations APCC (2006) are as follows:
Grade I = Refined and deodorized oil (oil that has been purified and removed the smell)
Grade II = Refined oil (oil that has been purified)
Grade III = White oils obtained by wet processing (no colored oil (nodes) obtained from pegolahan wet method)
Grade IV = Industrial Oil No. 1-obtained by the process of extraction (oil Industry No. 1 - obtained by extraction)
Grade V = Industrial Oil No. 2-obtained by the process of solvent extraction (oil Industry No. 1 - obtained by extraction using a solvent)
Quality requirement of each class of quality (grade) are presented in Table 5 below.
