16、ntical text or by endorsement, at the latest by April 2006, and conflicting national standards shall be withdrawn at the latest by April 2006. Regarding types 1 and 2 France asked for a national deviation due to a French national regulation (decree no 96-465 of June 4, 1996), see Annex C. This docum

34、he colour of the ring shall be orange. For classes A and B, 12 net fixings shall be equally spaced on the underside of the ring element. When tested in accordance with 5.2.2, pressure release rings, after release and with the load no longer applied, shall return automatically and instantly to the or
35、iginal position. When tested in accordance with 5.2.3, all rings shall show no rupture and no permanent deformation of more than 10 mm. 3.4.3 Nets in classes A to D The colour of the net shall be white. The net shall be made of net yarn with a breaking force of at least 1 700 N. Net yarn shall be no
36、t less than 4,5 mm minimum diameter. When attached to the ring the net shall hang vertically from the net fixings with an overall length of (400 500+) mm. NOTE The net should offer sufficient resistance to the passage of a basketball of 749 mm to 780 mm circumference to slow down the flight of the b
37、all. This makes it possible that it can clearly be determined visually whether the ball has or has not passed through the net. 3.4.4 Framework in classes A to D For basketball equipment that is designed to permit height adjustment of the backboard with basket and net, lock-ing devices shall be fitte
38、d at 3 050 mm1)and 2 600 mm (mini basketball), see h1in figure 8. After height adjustment the horizontal distance from the backboard to the playing court shall not change. 1) in line with FIBA regulations EN 1270:2005 (E) 12 3.4.5 Rigidity 3.4.5.1 When tested in accordance with 5.4 with a force F1,
39、the horizontal permanent deflection of the frame-work after removal of the test force, ready for use, from the zero position shall not be more than 10 mm. 3.4.5.2 When tested in accordance with 5.4 with a force F3for indoor equipment, the horizontal permanent de-flection of the framework after remov
40、al of the test force, ready for use, from the zero position shall not be more than 10 mm. If the equipment can be used outdoors, the horizontal permanent deflection of the framework after removal of the test force, ready for use, from the zero position shall not be more than 10 mm, when tested in ac
41、cordance with 5.4 with a force F4. 3.4.6 Stability When tested in accordance with 5.5 with a force F2, the vertical permanent deflection of the framework after re-moval of the test force, ready for use, from the zero position shall not be more than 10 mm. 4 Safety requirements 4.1 General All corner
42、s and edges up to a height of 2 900 mm, which are exposed within the playing court area free space and are not protected by padding, shall be rounded with a radius of at least 3 mm or be chamfered. The edges of the backboard shall be chamfered or padded. 4.2 Ring The ring shall be fixed on the frame
43、work in such a manner so that no force, transmitted by the ring, is directly ap-plied to the backboard. The fixing plate shall be designed such that it does not protrude the lower edge of the backboard. Pressure release rings shall meet the following requirements: a) there shall be no gaps between t
44、he bracket and the ring that create a danger of entrapment; b) the pressure release mechanism shall not disengage until a static load of 1 050 N has been applied to the top of the ring at the most distant point from the backboard; c) when disengaged the housing of the pressure release mechanism and
45、fixing shall not have any gaps greater than 8 mm; d) when disengaged the ring shall not deflect more than 30 below the original horizontal position.

NOTE A net attachment according to Figure A.1 fulfils this requirement. 4.4 Heigh
47、t adjustment and storage position The construction to adjust the height of the backboard and to store it shall prevent unintentional changes during use. During activation of the height adjustment system the operator shall be able to view both the adjustment mecha-nism and the backboard. NOTE 1 These
48、 requirements also relate to hoisting the whole equipment. NOTE 2 The future European Standard on hoisting devices will also apply. 4.5 Padding for classes A and B (see Table 6) 4.5.1 The backboards shall be padded as follows: a) for the bottom and sides of the backboards the padding shall cover the
49、 bottom edge and side edges to a dis-tance of 350 mm from the bottom; b) for the front and back surface the padding shall cover to a minimum of 20 mm from the bottom (see Figure 12). 4.5.2 The supports shall be padded as follows (see Figure 12): a) for the bottom surface of any backboard support behind the backboard and at a height of less than 2 750 mm above the floor shall be padded on to a distance of 1 200 m from the face of the backboard; b) fo
