Accessible sampling cocks should exist on all cooling systems for each diesel engine. This including, but not limited to, main jacket water, piston cooling, fuel oil valve, auxiliary engines, low temperature systems, etc. A representative sample must be taken from each cooling water system to be tested. To minimize the effort in obtaining cooling water samples, a sample cock located in a position to draw a sample/having access to draw the sample quickly and easily, will make the task of drawing samples simple. Before taking the sample the sampling line if present, should be thoroughly flushed with cooling water to ensure a representative sample is used for testing. In each case of drawing a sample, the container should be filled with the water to be tested, sealed and labelled. It is advisable to conduct the appropriate tests within 30 minutes of drawing the sample, although this time limit can be extended when the sample container is completely filled and sealed.
