Diagram 1 Backstop unit 2 Backboard 2.1 The backboards shall be made of a suitable transparent material (for Level 1 and 2, of a tempered safety glass), made in one (1) piece, non reflective, with a flat front surface and shall:  Have a protective framework of the backboard support structure around the outer edge.  Be manufactured such that, if broken, the pieces of glass do not split off. 2.2 For Level 3, the backboards may be made of other material(s) painted white, but must meet the other above specifications. 2.3 The backboards shall measure 1,800 mm (+ a maximum of 30 mm) horizontally and 1,050 mm (+ a maximum of 20 mm) vertically. 2.4 All lines on the backboards shall be:  In white, if the backboards are transparent.  In black, if the white painted backboards are non-transparent.  50 mm in width. 2.5 The borders of the backboards shall be marked with a boundary line (Diagram 2) and an additional rectangle behind the ring as follows:  Outside dimensions: 590 mm (+ a maximum of 20 mm) horizontally and 450 mm (+ a maximum of 8 mm) vertically.  The top edge of the base of the rectangle shall be level with the top of the ring and 150 mm (- 2 mm) above the bottom edge of the backboard. OFFICIAL BASKETBALL RULES 2010 Basketball Equipment April 2010 Page 7 of 21 2.6 For Levels 1 and 2, each backboard shall be equipped with lighting around its perime￾ter, mounted on the inside borders of the backboards and which lights up in red only when the game clock signal sounds for the end of a period. The lighting shall be a minimum of 10 mm in width and cover a minimum of 90 % along the edge of the backboard glass area. Diagram 2 Backboard markings 2.7 The backboards shall be firmly mounted on the backboard support structures at each end of the playing court at right angles to the floor, parallel to the endlines (Diagram 1). The central vertical line on their front surfaces, extended down to the floor, shall touch the point on the floor which lies 1,200 mm from the centre point of the inner edge of each endline, on an imaginary line drawn at right angles to this endline. 2.8 Rigidity test for the backboard tempered safety glass:  When a square-shaped weight of 50 kg (250 mm wide and high, and 1,100 mm long) is applied along the centre of the backboard glass (without its frame), which is placed horizontally on two (2) parallel wooden bars at a distance of 1,200 mm from each other (Diagram 3), the maximum vertical deformation shall be 3 mm. Diagram 3 Rigidity of the backboard glass  When a basketball is dropped onto the backboard, it shall rebound from it with a minimum rebounding height of 50%. Basket Equipment.indd 6 22.12.10 11:37
