Annex 2 - Preparing sample sand

For any test to be undertaken the sample sand should represent a good average of the stock. When the sand is stored, finer particles tend to separate out a bit. Therefore take sand from at least 6 different places in the deposit and place it on the floor in a heap. Part this heap into four parts, take two parts away and make a new heap. Part the second heap into four parts and take two parts away. Take about 200 g of the remaining parts for testing.
