2- Procedure
Made of hard Material, having a square section of
side (40 ±1)mm and a length of 200 mm.A further
length of 120mm of handle.
6- Thermometer 7- Rule Or Measuring Tape
A minimum length 700 mm and having
Sub-divion not greater than 5 mm alongentire length.
Made of hard non-absorbent material to
ensure proper mixing of concrete.
A container made from non-absorbent
material not attacked by cement paste,with appropriate dimensions such that
the concrete can be toughly re-mixed.
3- Tamping Bar2- Mould
It is not applicable to self-compacting concrete, formed concrete or non-fines concrete, nor to concrete with maximum aggregate size exceeding 63mm.
Before taking a sample of freshly mixed concrete, dampen the
sampling container (wheelbarrow) toughly by clean water.
Take a sample of freshly mixed concrete by using every
precaution that assist in obtaining sample that are trulyrepresentative of the nature and condition of concrete. Take
enough sample to perform the flow table test and if there is
any test specimen required to take for testing.

BS EN 12350-Part-5:Flow Table Test.
Testing Fresh Concrete
This European standard specifies a method for determining the flow of the fresh concrete.
This test determine the consistency of fresh concrete by measuring the spread of concrete on a flat plate which is subjected to jolting.
