16、able 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 filled synthetic turf and unbound mineral surfaces, laboratory tests are considered to give a more precise indic

17、ation of how a surface will perform. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

18、erenced document (including any amendments) applies. EN 12229, Surfaces for sports areas Procedure for the preparation of synthetic turf and needle-punch test pieces 3 Principle Water is ponded within two concentric cylinders that have been sealed onto or hammered into the sports surface. The outer

19、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 4.1 Infilt

20、rometer, 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 to minimise lateral leakage. 4.1.1 Large cylinder, double-ring infiltrometer, for t

21、ests on synthetic turf and synthetic surfaces and mineral and natural turf 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 a

22、rea to prevent the lateral flow of water from the inner cylinder. 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 mineral surfaces with a rate of water infiltration greate

23、r 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

24、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.

28、2616:2013EN 12616:2013 (E) 6 5 Method A Synthetic turf, textile, synthetic and bound mineral sports surfaces 5.1 Test specimen laboratory tests A piece of sports surface of minimum length 1 000 mm and minimum width 1 000 mm, in combination with the supporting layers to be used in service, if require

29、d, and using the recommended method of attachment in accordance with the manufacturers instructions. The test specimen shall be selected so the infiltrometer is positioned with the minimum number of drainage holes (perforated into the sports surface backing) possible within the two rings. Prepare la

30、boratory 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 site Unless specified in the product standard, test locations on site

31、 shall be selected be as follows. On sports surfaces of less than 3 000 m2in area, at least one test reading shall be performed per 500 m2. On sports surfaces larger than 3 000 m2at least one test reading shall be performed per 1 000 m2. All test locations shall be selected at random. 5.4 Procedure

32、5.4.1 If 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 o

33、nto 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. 5.4.2 Pond water in both cylinders until the flow of water into the inner

34、 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. 5.4.3 Measure the time (tA) for the water to fall by 20 mm from an initial ponding depth of (30 1) mm to a final ponding dep

35、th 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 slop

36、e, 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 water infiltration rate IA, expressed in millimetres per hour, from the following formula: AWAAtFI = where BS EN 12616:2013EN 12616:2013 (E) 7 FWAis th

37、e fall of water level (mm); tAis the time taken for the water level to fall (h). 6 Method B Natural turf 6.1 Number and distribution of test locations Take at least six readings at random on sports surfaces of less than 100 m2, take between seven and 10 readings, as appropriate, at random on sports

38、surfaces of 100 m2to 1 000 m2and take between 10 and 20 readings, as appropriate, at random on sports surfaces of 1 000 m2to 5 000 m2. Subdivide larger sports surfaces into two or more sections and test each section as above. 6.2 Procedure 6.2.1 Hammer the cylinders of the double ring infiltrometer

39、(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. 6.2.2 Pond water in both cylinders, as described in 5.4.2. Ideally, infiltration rates should be measured when soil moist

40、ure 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. 6.2.3 Measure the fall in water level (FWB) in the inner cylinder from an ini

41、tial 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 cylinder. 6.3 Calculation and expression of results Calculate th

42、e water infiltration rate IB, expressed in millimetres per hour, from the following formula: where FWBis the fall of water level (mm); tB is the time taken for the water level to fall (h). 7 Method C Unbound mineral surfaces 7.1 Number and distribution of test locations Take at least five test readi

43、ngs at random on sports surfaces of less than 6 000 m2. Subdivide larger sports surfaces into two or more sections and test each section as above. BS EN 12616:2013EN 12616:2013 (E) 8 7.2 Procedure 7.2.1 Thoroughly moisten the sports surface before hammering the cylinders into the sports surface to a

44、 depth of (25 5) mm, taking care to seal any cracking along the unbound mineral sports surface/cylinder interface by pressing down the unbound mineral material around the wall of the infiltrometer. 7.2.2 Pond water in the cylinders as described in 5.4.2. If steady-state is not achieved after 20 min,

45、 pond water until the water level in the inner cylinder has fallen by 25 mm from an initial level of 35 mm to 45 mm. 7.2.3 Measure the fall in water level (FWC) 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 f

46、or the water to fall 25 mm. At all times ensure that the water level in the outer cylinder is within 2 mm of the level in the inner cylinder. 7.3 Calculation and expression of results 7.3.1 Calculate the water infiltration rate IC, expressed in millimetres per hour, from the following formula: where

47、 FWC is the fall of water level (mm); tCis the time taken for the water level to fall (h). 7.3.2 Transform the numerical values to logarithms (base 10), or log10(x + 1). Calculate the mean from the log-transformed data and then transform back to the numbers represented by the logarithms to give the

48、fall of water level FWC. Express the results as the back-transformed value of water infiltration rate. 8 Test report The test report shall include the following information: a) reference to this European Standard, i.e. EN 12616:2013; b) method used, i.e. Method A, Method B or Method C; c) apparatus
