The fresh mortar for this test shall have a voiwne of not less than 50 times the maximum aggregate particle size, wid in no case less than 50 nil or 1,5 tinws the quantity needed to perform tire test, whichever is the greater. It shall be obtained either by reduction of the bulk test sample (sec EN 1015.2) using a sample divider or by quartering or by preparation from ehy constituents and water in the laboratory. The flow value of the mortar in the hulk test sample shall be (letI’rmIned in accordance with EN l0l53 and reported
Lalx)rdt()ly mixed samples shall, before testing, he brought to a defined flow value as specified In
EN 1015-2.
Ready to use mortars (factory-made wet mortars which are retanled). and pre-batched aJ.r-lmwJsan(l wet mortars when not gauged with hydraulic binders, shall be tested within their specified workable life.

Ilefore testing, the batch shall be gently stirred by hand usmg a trowel or palette knife in 5 s to lOs to counteract any false setting etc., but without any wkbtionai mixing of the batch.
Any deviation from the mixing procedure shall be noted.
