Role of an independent laboratory
• To determine the quality / quantity of the commodity
• The price of the goods is based on the quality / quantity
• Also the processing (refining & bleaching) is depending on the quality of the crude oils/fats
• All based on independent analyses, using contractual methods

Birth of an ISO-method • A member state proposes a method (New
Work Item Proposal) • This is balloted with the members for adding
to the work programme and for comments • These comments are evaluated and the
method is amended • An international ring test is organised • The ring test results are evaluated to see if
they meet the ISO statistical requirements

Birth of an ISO-method 2
• Additional comments (if any) are taken into account for the next version of the method
• Voting is performed • Method is accepted if the members agree • In general this procedure takes about 3
years • The methods are reviewed after 3/5 years

Laboratory certification
• The laboratory must be recognised by the contract organisations and others e.g. FEDIOL, VERNOF, GMP, QS
• By means of: – participation in ring trials, questionaires
and audits • Accreditation according to ISO 17025 is
recommended and appreciated
11

ISO 17025 accreditation
• Management and documentation quality system in compliance with ISO 9001
• Suitable, qualified employees • Using validated methods • Using calibration standards and equipment
that can be traced back to national standards • Yearly participation in proficiency tests • Yearly audit by Council for Accreditation
(RVA)

Tank cleaning procedure
• Butterworthing with fixed / transportable machines
• Depending on the melting point of the cargo, this must be done with cold / warm or hot seawater
• Followed by many cleaning cycles with (alkaline !!) detergents
• Afterwards the tank is rinsed with fresh water
33

Tank Cleaning final
• Inspection of the tank; visually and by means of wall wash tests
• Analyses of these wall washes on the spot or in the laboratory
• Calculation of the risk in case of any doubt
