For the purposes of thisstandard, the aggregate is referred to as railway ballast.It provides for the evaluation of conformity of the products to this European Standard.NOTE The requirements in this European Standard are based upon experience with aggregate types with an establishedpattern of use.
Care should be taken when considering the use of aggregates from sources with no such pattern of use, e.g.,recycled aggregates and aggregates arising from certain industrial by-products.
Such aggregates, that should comply with allthe requirements of this European Standard, could have other characteristics not included in Mandate M 125 (as amended) thatdo not apply to the generality of aggregate types with an established pattern of use and when required, provisions valid at theplace of use can be used to assess their suitability.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

When required, the tests specified shall be carried out to determineappropriate properties.NOTE 1When the value of a property is required but not defined by specified limits the value should be declared by theproducer as an XXDeclared category, e.g., in Table 4 a value of flakiness index of say 40 corresponds to FI40 (Declared value).NOTE 2When a property is not required, a “No requirement” category can be used.NOTE 3Guidance on selection of appropriate categories for specific applications can be found in national provisions in theplace of use of the railway ballast.6.2 Railway ballast sizeRailway ballast size shall be designated by a pair of sieve sizes in millimetre with d as the lower limit designationsieve and D as the upper limit designation sieve between which most of the particle size distribution lies.For railway ballast D is 50 mm or 63 mm and d is 31,5 mm.6.3 GradingThe grading of the railway ballast determined in accordance with EN 933-1 shall be declared in accordance withthe relevant category specified in Table 1.Table 1 — Categories for gradingRailway ballast size 31,5 mm to 50 mmRailway ballast size 31,5 mm to 63 mmPercentage passing by massGrading categorySieve sizemmABCDEF8063504031,522,431,5 to 5031,5 to 6310010070 to 9930 to 651 to 250 to 3 50-10097 to 10070 to 9930 to 701 to 250 to 3 50-10095 to 10070 to 9925 to 751 to 250 to 3 50-10097 to 9965 to 9930 to 651 to 250 to 3- 5010095 to 9955 to 9925 to 751 to 250 to 3- 5010093 to 9945 to 7015 to 400 to 70 to 7-³ 85NOTE 1
The requirement for passing the 22,4 mm sieve applies to railway ballast sampled at the place of production.NOTE 2
In certain circumstances a 25 mm sieve may be used as an alternative to the 22,4 mm sieve when a tolerance of0 to 5 would apply (0 to 7 for category F).6.4 Fine particlesThe content of fine particles determined in accordance with EN 933-1 shall be declared in accordance with therelevant category specified in Table 2.
