Otherwise, proceed as described in 5.1.3.1.1.3. 5.1.3.1.1.3 Examine the surface of the liquid. If there are signs of surface contamination, take samples from the surface as described in 5.1.3.1.2. Otherwise, take samples as described in 5.1.3.1.3. 5.1.3.1.2 Surface sampling Take a sample using a suitable ladle. Lower the ladle into the liquid until the rim is just below the surface, so that the surface layer runs into it. Withdraw the ladle just before it fills completely and allow any liquid adhering to the SIST EN 1203:2005
