identical text or by endorsement, at the latest by February 2006, and conflicting national standards
shall be withdrawn at the latest by February 2006.
This European Standard forms part of a series of tests for chemical properties of aggregates. Test
methods for other properties of aggregates are covered by Parts of the following European

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
filler aggregate
aggregate, most of which passes a 0,063 mm sieve, which can be added to construction materials to
provide certain properties
3.2
water susceptibility of filler
measure of the degree of separation which occurs in the presence of water from a filler bitumen
mixture, e.g. as a result of intra-crystalline water inclusion between aggregate particles and binder
coating
3.3
subsample
sample obtained from sampling increments or a bulk sample by means of a sample reduction
procedure
3.4
test portion
sample used as a whole in a single test
3.5
aggregate size
designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D
NOTE This designation accepts the presence of some particles which will be retained on the upper sieve
(oversize) and some which will pass the lower sieve (undersize).
3.6
particle size fraction
fraction of an aggregate passing the larger of two sieves and retained on the smaller
NOTE The smaller sieve size can be zero.
3.7
constant mass
successive weighings after drying at least 1 h apart not differing by more than 0,1 %, by mass
NOTE In many cases constant mass can be achieved after a test portion has been dried for a pre-
determined period in a specified oven at (110 ± 5) °C. Test laboratories can determine the time required to
achieve constant mass for specific types and sizes of sample dependent upon the drying capacity of the oven
used.
4 Principle
A mixture of filler and bitumen is stirred in hot water. If filler becomes separated from the mixture
(indicated by the turbidity of the water), the filler is recovered on a filter paper and weighed.
