EN 16027:2011 – Protective clothing – Gloves with protective effect for association football goal keepers
For each of the required sequences of measurement performed in accordance with this standard a corresponding estimate of the uncertainty of the final result shall be determined. The uncertainty of measurement shall be expressed in the form ± X. It shall be used in determining whether a “PASS” performance has been achieved. If the final result minus X is below the pass level and there is the requirement that a certain value shall be exceeded then the sample shall be deemed to have failed. NOTE It is anticipated that values of uncertainty of measurement will usually be between 2 % and 5 % of the measured value for force and length measurements.
5.2 Sampling and conditioning Two pairs of unused gloves for goal keepers of each size distributed to the market shall be provided for testing. The samples shall be conditioned for at least 24 h in an atmosphere of (20 ± 2) °C and a humidity of (65 ± 5) %. Testing shall be carried out in the conditioning environment or within 10 min of removal from that environment.
5.3 Ergonomics At least two sizes of gloves, one sample each, shall be used. Each sample shall be put on and adjusted by a subject of appropriate dimensions of the intended user according to the information supplied by the manufacturer. Check by visual and/or tactile inspection that the glove is free of hard or sharp edges or corners, seams and buckles and that the restraint system does not constrict the user in use.
For testing the typical movements, a subject shall catch and fist a ball according to the rules of association football. The subject shall report any restrictions or severe discomfort when executing typical moves. The size of the gloves with protective effect shall be tested according to EN 420:2003+A1:2009, 6.1.3.
5.4 Stiffness
5.4.1 Apparatus The apparatus is illustrated in Figure 1. The apparatus comprises a palm support on which to place the palm of the glove to be tested and a finger support on which to place all fingers of the glove except the thumb. The finger support is attached to a pivot table lever. A scale enables measurement of the pivot angle of the lever with an accuracy of ± 1°. The surfaces of the palm support and of the finger support are on same level with accuracy of ± 0,2 mm. The pivot axis of the lever is (18 ± 0,2) mm below the upper surface of the finger support. The apparatus further comprises a holding bar to press down the glove to the palm support. The surface of this bar facing the glove is plane with a radius of (3 ± 0,1) mm on both long edges of the bar.
The total width of the bar shall be 15 mm and the length minimum 200 mm. The long axis of the bar shall be parallel to the pivot axis with an accuracy of ± 0,5°. The horizontal distance of long axis of the bar to the pivot axis shall be (17,5 ± 0,2) mm.
A guiding system shall be provided to keep the holding bar in horizontal orientation with an accuracy of ± 1°. The holding bar shall be weight loaded so that it shall be pressed down to the gloves upper surface with a force according to Table 1. A force to pivot the lever shall be applied radial to the pivot axis with a distance of (170 ± 5) mm.
The force shall be measured by a strain gauge or other appropriate instrumentation with an accuracy of ± 0,5 N. To replace the fingers of the hand, the fingers of the gloves except the thumb shall be filled with extension springs according to EN 13906-2 with the following specifications: De=15 mm, d=1,5 mm, spring steel according to EN 10270-1, any grade, length min. 200 mm.
