• changes and clarifications to the sampling and sample reduction clauses, including a new informative annex on sampling from waterborne plant; • introduction of requirements for sample preparation for the Micro-Deval test previously in EN 13383-1; • deletion of an unused wet sieving method for the determination of particle size distribution of coarse gradings of armourstone. • removal to an informative annex of a previously normative alternative to the reference method for determination of mass distribution of light and heavy gradings. Otherwise the majority of the changes from the previous version are editorial.

250 mm, 180 mm and 125 mm sieves and ± 1,0 mm for the 90 mm and 63 mm sieves. In all cases the 63 mm sieve shall be used. Perforated steel plate sieves shall be in accordance with EN 933-2. 5.2.3 Test sieves, apertures conforming to ISO 3310-2 with apertures smaller than 63 mm. 5.2.4 Receivers, with a volume of at least 0,1 m3, on which the sieves will fit. 5.2.5 Weighing equipment, with a weighing capacity of at least 150 kg, accurate to 0,5 kg.

Mi is the mass of material retained on a sieve, in kilograms;
ΣMi is the cumulative mass of material retained on all sieves, in kilograms;
m3 is the mass of material passing the sieve with the smallest aperture size, in kilograms. Calculate the cumulative percentage mass (Ri) retained on each sieve to the nearest 0,1 %. Calculate the cumulative percentage mass passing each sieve (Pi) from the following formula:
Pi = 100 - Ri Record to the nearest whole number. 5.6 Test report 5.6.1 Required data The test report shall include the following information: a) reference to this European Standard; b) identity of laboratory; c) identification of the sample; d) mass of test portion; e) cumulative percentages of the masses passing each of the sieves, to the nearest whole number; f) date of test. 5.6.2 Optional data The test report can include the following information: a) name and location of the sample source; b) description of the material and of the sampling procedure; c) graphical presentation of results. 6 Determination of the mass distribution of light and heavy gradings 6.1 Principle The test consists of dividing a material into several fractions by means of weighing individual pieces of armourstone. The average mass of the pieces of armourstone is derived by dividing the total mass excluding fragments by the number of pieces of armourstone. A reference method is specified. The use of other methods not described in this standard for determining mass distribution are permitted, in particular for factory production control, provided that an appropriate working relationship with the reference method has been established. SIST EN 13383-2:2013

6.4 Procedure Weigh each piece of armourstone heavier than a fragment separately (Mi) to ± 5 % of the nominal lower limit of the grading. Weigh all fragments together (Mf) to ± 5 % of the nominal lower limit of the grading. SIST EN 13383-2:2013
