Sampling 1. Using the coherent sampling method The sampling method which has been used by both parties (seller and buyer) needs to be clearly stated and communicated between the seller and the buyer. Any sampling method will induce a margin of error, which both parties will communicate to each other. 2. The ISO standard The ISO standards (and more particularly ISO 4552 & 3713) set the sampling & sample preparation methods. 3. Sampling practice The sampling is conducted in accordance with the best possible practice, the ISO methods should be used as the constant reference, and especially ISO 3713. Parties shall keep samples for possible cross-checks and umpires. In case the delivery of one lot is made by several trucks or containers, it is understood that the sampling must be conducted on the whole lot delivered, and not on one single truck or container. In case the delivery is made by vessel or barge in bulk, the whole shipment will be sampled. 6
