TIC Companies are frequently asked to prepare composite samples in non laboratory environments such as the deck of a marine vessel or on the top of a shore tank. These samples are often referred to as “Deck Composites” or “Field Composites”. While such samples may be considered necessary as a matter of expediency, TIC Council would like to point out that the use of such composite samples and any analysis derived from them can be very problematic. TIC Council recommends that composite samples prepared in non laboratory environments should be avoided and that its members’ clients review their current sampling instructions and explore alternatives to this type of sampling. The reason most frequently given for preparing deck composites is to provide a sample to be retained on board after a ship has loaded. Non representative nature of deck composite samples with uncertain sample storage conditions on board, generally lead to these samples being rejected in the case of a dispute. #Deck Composite #TIC council #VTIC services #technical Bulletin
