5. SAMPLING5.1. In Drums

The sample shall be taken at random from the square root of the number ofdrums in a consignment with a maximum of 30 drums per consignment. Thesample shall be taken lrom each drum with sampling tube with valve of 125cm in length and a diameter of + 2 cm.

The orifice of the pipe can be closed or opened by a long stemmed plug. Byimmersing this pipe into the drum, the oil shall be sampled from the upper layerclown to the bortom layer. Samples shall be taken at four cliagonally tppo.itecorners and the four samples are then mixed together and from this mixture Ikg shall be taken fbr analysis.5.2. In Bulk

Tl-re sarnple shall be taken as a systematic sampling using the specificeqr'ripments as much as I kg of sample from the outflow tap of the pipe throughwhich the oil flows from the land tank to the ship.The sampling oificial shall be a person with experience or training andernployecl by i,r leg;il body.

6. METHODS OF TEST6.1 Determination of Free Fatty Acid6.t.I Principle

Test Procedureweigh to the nearest 10 mg about 2 - 50 g of the sample into a flaskHeat to boiling 50 ml of the ethanol in a second flask. while thetempelature of the ethanol is still 70 C neutralize with the KOH 0. I Nsolution, using 0.5 ml of phenolphthaleinAdd the solution tiom the second flask into the test portion in the firstflask and heat to the boiling point and titrate to the end point with the KOH0. lN solution.6.1.5 Expression of results

Express the results as a percentage by mass of lauric acid using the formula:2.00 T NLauric acid =

Where :T is the volume (mi) of NaOH used for the titration.N is the normality of NaOHW is the mass (g) of the sample.

6.2 Determination of Impurities Content6.2.1 Principle

Treatment of a test portion with an excess of n-hexane or light petroleum,then flltration of the solution obtained. Washing of the filter and residue with

w

the same solvent, drying at 103 +2oC. and weighing.Reagents

Petroleum ether orless than 1 n-Hexane. boiling range 400C to 600C,bromine valueCarbon disulphide, fieshly distilled before use

Test Procedureweigh about 5 g of sarnple to the-nearest 0.1 g into a flask.Melt the test portion, add 250 ml of petroleum ether, close the flash withthe ground glass stopper and shake. Ailow to stand overnight.Decant the solution carefully through an ashless filter paper and dry inthe oven at a temperature of 103 + 2 C.Remove trom the oven, close the vessel with its lid, allow to cool in thedesiccator and weigh to the nearest 0.001 g.
