14、ommittee CEN/TC 217 “Surfaces for sports areas”, the secretariat of which is held by BSI.This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2004, and conflicting national standards shall be
15、withdrawn at the latest by December 2004.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard : Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hu

17、 surfaces, shock pads and loose-laid synthetic surfaces when subjected to varied water, frost and heat conditions.2PrincipleA comparison between the dimensions in the plane of a test piece parallel and perpendicular to the direction of its manufacture is made before and after it has been subjected t
18、o varied water, frost and heat conditions.3Apparatus3.1Test apparatus3.1.1 Support, to hold the test piece during conditioning and the taking of measurements.3.1.2 Metal plate, with a mass of (15 1) kg/m2, of dimensions along each edge (10 1) mm smaller than the test piece.3.1.3 Instrument with a ga
19、uge, capable of measuring the length of the test piece to the nearest 0,01 mm.Dimensions in millimetresFigure 1 Test apparatus3.2Container, for holding water at (23 2) C, of dimensions at least 20 mm greater than the test piece and deep enough to accommodate the submerged test piece.3.3Deep-freeze,
20、capable of being maintained at a temperature of (-18 2) C, of dimensions at least 20 mm greater than the test piece.3.4Drying oven, with forced ventilation, capable of being controlled at (70 2) C, and having perforated and lacquered shelves.3.5Enclosure for conditioning, capable of providing a stan
21、dard atmosphere of (50 5) % relative humidity and a temperature of (23 2) C.4Sampling, preparation of test pieces and conditioning4.1SamplingSynthetic turf and textile surfaces incorporating integral shock pads shall be tested as a complete unit.Each component of systems incorporating loose-laid syn
22、thetic turf, textile surfaces, shock pads and synthetic surfaces shall be tested separately.4.2Preparation of test piecesTake at least three samples as delivered by the manufacturer, having a length of (400 10) mm and a width of (400 10) mm, and mark the direction of manufacture.Make three marks on
23、the edges of the test piece on the backing, two 50 mm from each corner and one halfway along the edge. Make a similar set of marks on the adjacent edge. Make the marks in the direction of manufacture and at right angles to it.4.3ConditioningCondition the test pieces at (50 5) % relative humidity and
24、 a temperature of (23 2) C for at least 48 h.5Procedure5.1GeneralTest pieces taken from carpets shall be tested upside down.For sand- or rubber-filled surfaces, perform the test without sand or rubber.5.2Initial measurement of the test piecePlace the conditioned test piece on the metal plate (3.1.2)
25、 with the backing uppermost. Determine the length of the test piece at the three marks equally spaced over the total length, using the test apparatus described in3.1, measure and record the distance between the marks on the edges parallel to and at right angle to the direction of manufacture to the
26、nearest 0,1 mm.Place the metal plate (3.1.2) on the test piece.5.3Determination of dimensional changeImmerse the test piece, laid flat, into a container (3.2) containing water and 0,1% sodium lauryl sulfate at a temperature of (23 2) C. Allow it to soak in the water for (24 1) h.Remove the test piec
27、e from the water and make the measurements described in 5.2 no later than 5 min after removal. Note and record the appearance of the test piece.Immediately after measurement, place the test piece in the deep-freeze (3.3), Iying freely but flat at a temperature of (-18 2) C. Leave it in the deep-free
28、ze for (24 1) h.Remove the test piece from the deep-freeze and make the measurements described in 5.2 no later than 5 min after removal. Note and record the appearance of the test piece.Dry the test piece for (72 1) h in a drying oven (3.4) at (70 2) C, Iying freely but flat on the perforated shelve
29、s.Immediately after removing the test piece from the oven, make the measurements described in 5.2. Note and record the appearance of the test piece.Finally, leave the test piece for (48 1) h in the conditioning enclosure (3.5). Make the measurements described in 5.2. Note and record the final appear
30、ance of the test piece.6CalculationCalculate, for each test piece, the percentage variation in each measurement using the formula:l lL= mo 100lowhere:lo is the initial length;lm is the length at each of the stages referred to in clause 5.Indicate a decrease in dimensions by a minus sign, and an incr
31、ease in dimensions by a plus sign.Calculate the arithmetic mean for each test piece in each direction and for each stage referred to in clause 5.7Test reportThe test report shall include the following:a)reference to this European Standard, i.e. EN 13746:2004;b)complete identification of the surface
32、tested, including the manufacturers reference and its previous history;c)for each test piece, the individual values of the length measurements parallel and at right angles to the direction of manufacture, together with the results obtained as specified in clause 6;d)a description of the appearance o
33、f the test pieces at each stage and their final appearance;e)type of measuring instrument used.BS EN13746:2004BSI389 Chiswick High RoadLondonW4 4ALBSI British Standards InstitutionBSI is the independent national body responsible for preparingBritish Standards.
