EVS-EN 12350-2:2002

This standard specifies a method for determinig the consistency of fresh concrete by the slump test. The slump test is sensitive to changes in the consistency of concrete which correspond to slumps between 10 mm and 200 mm. Beyond these extremes the measurement of slump can be unsuitable and other methods of determinig the consistency should be considered. The slump continues to change over a period of 1 min after de-moulding, the slump test is not suitable as a measure of consistency. The test is not suitable when the maximum size of aggregate in the concrete is greater than 40 mm.
