This European Standard shall be given the status of a national standard, either by publ
19、ication of an identical text or by endorsement, at the latest by October 2001, and conflicting national standards shall be withdrawn at the latest by October 2001. This standard EN 12503 “Sports mats“ consists of: Part 1: Gymnastic mats, safety requirements Part 2: Pole vault and high jump mats, saf
20、ety requirements Part 3: Judo mats, safety requirements Part 4: Determination of shock absorption Part 5: Determination of the base friction Part 6: Determination of the top friction Part 7: Determination of static stiffness According to the CEN/CENELEC Internal Regulations, the national standards o
21、rganizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

23、tes, 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. For dated references, subsequent amendments to or revisions of any of these publications apply to this Europea

EN 12503-3:2001 Sports mats Part 3: Judo mats, safety requirements EN 12503-4:2001 Sports mats Part 4: Determination of shock ab
25、sorption 3 Principle An indentor is applied to the mat under a specified mass and the deflection of the mat normalised to the deflection at a set distance for the point of indentation is measured (see figure 1). 4 Apparatus Means of applying a load of (50 0,5) kg through an indentor vertically onto
26、the mat and a means of measuring the difference between the deflection under the centre of the indentor and the deflection at a diameter of (160 1) mm. A suitable form of apparatus is shown in figure 1. The indentor shall be 78 mm diameter and as specified in figure 2 of EN 12503-4:2001. The deflect
27、ion of the mat is conveniently measured in millimetres by means of a scale attached to the indentor and a circular aluminium or rigid plastic plate 160 mm diameter with a central hole 80 mm diameter. 5 Test piece The test piece shall be the complete mat. 6 Conditioning Condition the test pieces for
28、a minimum of 24 h at (21 3) C immediately before the test and carry out the test at the same temperature.

30、surface of the mat under a total load of (50 0,5) kg. Measure the difference between the deflection under the centre of the indentor and the deflection at a diameter of (160 1) mm 2 min 5 s after applying the load. Repeat the measurement to obtain readings at four positions which are approximately a
31、t the centre of each quarter of the mat. NOTE The readings are not to be taken at the same positions as used for measurement of shock absorption (see EN 12503-4:2001). 8 Expression of results Determine the mean of the measures of deflection. 9 Test report The test report shall include the following
32、information: a) the number of this standard, i.e. EN 12503-7; b) complete identification of the mat tested including type, manufacturers reference and previous history; c) the temperature at which the test was carried out; d) the mean deflection; e) the individual test values if required; f) details
33、 of any deviation from the procedure.
