Method A is suitable for synthetic, textile, synthetic turf and bound mineral sports surfaces, Method B is suitable for natural turf and Method C is suitable for unbound mineral sports surfaces. NOTE For unbound mineral surfaces, laboratory tests are considered to give a more precise indication of how a surface will perform. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter.

EN 12229, Surfaces for sports areas Procedure for the preparation of synthetic turf and textile test pieces. 3 Principle Water is ponded within two concentric cylinders that have been sealed onto or hammered into the sports surface. The outer cylinder is used as a buffer area to prevent the lateral flow of water from the inner cylinder. NOTE A single cylinder can be used if the test piece is fully sealed to prevent lateral flow of water. The rate of entry into the sports surface from the inner cylinder is measured. 4 Apparatus 4.1Infiltrometer, with dimensions specified in 4.1.1, 4.1.2 and 4.1.3, consisting of one or two metal cylinders (see Figure 1) capable of being sealed onto, or hammered perpendicularly into, the sports surface, as appropriate (see Figure 2). 4.1.1 Large cylinder, double-ring infiltrometer, for tests on surfaces with a rate of water infiltration less than 500 mm/h, consisting of an inner cylinder of inner diameter (300 5) mm forming the measurement area and an outer cylinder of inner diameter (500 25) mm forming the buffer area to prevent the lateral flow of water from the inner cylinder. NOTE A wide tolerance on the cylinder diameter is permitted to allow the cylinders to be stacked for ease of transport. 4.1.2 Small cylinder, double-ring infiltrometer, for tests on surfaces with a rate of water infiltration greater than 500 mm/h and where the available water supply is limited, consisting of an inner cylinder of inner diameter (150 5) mm and an outer cylinder of diameter (300 25) mm. 4.1.3 Single ring infiltrometer, in cases where the test piece can be fully sealed to prevent lateral flow of water, e.g. when measuring the rate of water infiltration in the laboratory, consisting of a single cylinder of dimensions conforming to the inner cylinder dimensions of 4.1.1 or 4.1.2.

Prepare laboratory tests specimens of either synthetic turf or textile materials in accordance with EN 12229. 5.2 Test conditions Tests shall be carried out at the prevailing site conditions. 5.3 Number and distribution of test locations On sports surfaces of less than 3 000 m2 in area, at least one test reading shall be performed per 500 m2. On sports surfaces larger than 3 000 m2 at least one test reading shall be performed per 1 000 m2. All test locations shall be selected at random. 5.4 Procedure 5.4.1If sealing of synthetic turf is required, remove any particulate fill by vacuum to allow the rings to seal onto the primary backing of synthetic turf carpets and assist the prevention of lateral seepage of water. Do not disturb the particulate fill in the measurement area. Seal the cylinders onto the sports surface with sealing material (4.5) taking care to ensure that the sealing material does not restrict water infiltration from any of the area enclosed by the inner cylinder. Apply the weights (4.7) if necessary. 5.4.2Pond water in both cylinders until the flow of water into the inner cylinder is constant and the water level approaches a steady state value. Ensure that the water level in the outer cylinder is within 2 mm of the level in the inner cylinder. 5.4.3Measure the water temperature in the inner cylinder. 5.4.4Measure the time (tA) for the water to fall by 20 mm from an initial ponding depth of (30 1) mm to a final ponding depth of (10 1) mm, or the fall in the water level (FWA) after a minimum of 30 min, whichever is quicker. NOTE The water levels between the cylinders can be maintained by the use of a siphon. Where a siphon has been employed, remove it before making any measurements. If the test piece is laid on a slope, measure the depth of water at the location in each ring with the greatest depth of water. 5.5 Calculation and expression of results Calculate the temperature-corrected water infiltration rate IA, expressed in millimetres per hour, from the following equation: A WA A t CF I = where FWAis the fall of water level (mm); Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 14:40:39 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 12616:2003 (E) 8 tAis the time taken for the water level to fall (h); Cis the appropriate temperature correction factor given in Table 1, to correct the infiltration rate to a standard temperature of 10 C.

Subdivide larger sports surfaces into two or more sections and test each section as above. 6.2 Procedure 6.2.1Hammer the cylinders of the double ring infiltrometer (4.1) into the surface to a depth of (50 5) mm, taking care to seal any cracking along the soil/cylinder interface by pressing down the soil around the wall of the infiltrometer.

NOTE Ideally, infiltration rates should be measured when soil moisture levels are high, and in this case a wetting-up period of 20 min should be used. If tests are carried out in dry summer weather, at least one hour should elapse between the start of ponding and the start of measurement. 6.2.3Measure the fall in water level (FWB) in the inner cylinder from an initial ponding depth of 30 mm over a time of 20 min. In cases when drainage is more rapid, record the time for the water to fall 25 mm. In all cases maintain the water level in the outer cylinder to within 2 mm of the level in the inner cyl
