14、6 EN 14953:2005 (E) 3 Foreword This European Standard (EN 14953:2005) has been prepared by Technical Committee CEN/TC 217 “Surfaces for sport 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 identica
15、l text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the latest by May 2006. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Aust
16、ria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 14953:2005 (E) 4 1 Scope This
17、 European Standard describes two methods for determining the thickness of granular materials within a structure. The two methods can be used to provide an indication of the thickness of surfacing material, one using a steel tape, the other using a floating disc and a steel tape. Method 1 is applicab
18、le to layers within a profile. Method 2 measures the thickness of a material at the surface. 2 Method 1 Profile and divider method 2.1 Application This method is suitable for determining the thickness of granular materials on-site or in the laboratory, provided that a profile can be removed without
19、destroying the structure. 2.2 Principle A hole is excavated within the structure to reveal a cross-sectional profile of the layers. This enables the thickness of each layer of material to be measured. 2.3 Apparatus 2.3.1 Spade, which cuts cleanly. 2.3.2 Trowel. 2.3.3 Two-in flexible divider. 2.3.4 S
20、teel tape, graduated in millimetres. 2.3.5 1 m straight edge. 2.3.6 Corer, for laboratory analysis. 2.4 Test area Ensure that the test area is sufficiently moist to enable a clean cut to be made into the structure. If the thickness of a surface material is to be measured, the surface smoothness, i.e
21、. evenness, shall be within the limits of 2 mm under a 1 m straight edge. If surface evenness is not within these limits, the surface shall be tamped and levelled by luting within a tolerance of 2 mm under a 1 m straight edge. 2.5 Procedure Create on-site a vertical profile by digging a hole, no les
22、s than 300 mm x 300 mm square, to the depth required to reveal the layer or layers to be measured. For laboratory analysis remove a core no less than 150 mm in diameter with a corer. From the profile to be measured remove all loose surplus materials to give a smooth even face to the profile. Insert
23、the flexible divider above and below the layer in the profile of material to be measured (Figure 1). Remove the divider, measure and record the distance between its two points in millimetres (Figure 2). EN 14953:2005 (E) 5 Figure 1 Divider adjustment in profile Figure 2 Measuring the distance betwee
24、n the points of the divider 2.6 Calculation and expression of results Express the results in millimetres. If a profile has strata of varying thickness, measure the profile in three locations across its face, one on each side and one in the centre, and calculate the mean value. 2.7 Test report The te
25、st report shall include the following particulars: a) reference to this European standard, i.e. EN 14953:2005, Method 1; b) type of material under test; c) depth of profile excavated; d) average thickness of layer; e) condition of the ground at the time of the test; f) for surfacing materials, smoot
26、hness of the material, i.e. its evenness under a 1,0 m straight edge, prior to and after luting and tamping, as appropriate. EN 14953:2005 (E) 6 3 Method 2 Floating disc method 3.1 Application This method is suitable for the rapid testing of a number of areas for thickness of surfacing materials, wh
27、ere loose particulates are used. For very accurate measurement, i.e. within 2 mm, method 1 should be used. 3.2 Principle A smooth straight edge is laid over an excavated hole which is to the depth of the measurable layer. A floating disc is placed in the hole, lowered onto the top of the straight an
28、d locked onto the probe. The floating disc is removed and the distance between the bottom of the probe and the underside of the disc is measured and recorded. The thickness of the straight edge is measured and subtracted from the recorded figure. 3.3 Apparatus 3.3.1 1 m straight edge. 3.3.2 Steel ta
29、pe, graduated in millimetres. 3.3.3 Trowel or spade. 3.3.4 Floating disc (see Figure 3). 3.4 Test area Ensure that the test area is sufficiently moist, to enable the materials to be moved without breaking during the excavation. If the surface is undulated, ensure that the area is levelled (by luting
30、) and tamped to within a limit of 2 mm under a 1 m straight edge. 3.5 Procedure Remove the surface material down to the top of the next layer of material. Ensure that the excavation is sloping on two sides. Leave the other two sides free of excavated material for the positioning of the straight edge
31、. Lay the straight edge over the hole. Hold the probe of the floating disc vertically down the side of the straight edge with the tip resting at the bottom of the excavated hole. Lower the floating disc on top of the straight edge and lock it in position. Remove the probe from the hole. Measure the
32、thickness of the straight edge and subtract this from the depths recorded with the floating disc. Record the result in millimetres.

33、 Take three measurements over an area of 1,0 m x 1,0 m and calculate the mean value. 3.7 Test report The test report shall include the following: a) reference to this European Standard, i.e. EN 14953:2005, Method 2; b) type of material under test; c) size of the hole expressed in millimetres; d) con
34、dition of the test area, i.e. moist, saturated, etc.; e) method of recording the depth with a metal tape or a floating disc and metal tape; f) smoothness of the surfaces at the time of the test, i.e. its evenness under a 1 m straight edge, prior to and after luting and tamping, as appropriate; g) al
35、l measurements taken in each location and the mean result of each location.
