Technical details of the barriers.
The construction of the barriers.
The barriers should be constructed of metal or other suitable material, with the top bar of wood or other material
appropriate. It must consist of two bases and two rods supporting a rectangular frame reinforced by one or more bars
transverse rods being fixed at the ends of each base. The barrier should be made such that for
overturn it is required a force of at least 3.600 kg applied to the center of the top edge of the top bar.
The counterweights should be adjustable so that whenever power is required minimum and maximum 3.600 Kg
4kg. to break down the barrier.
Measures of barriers.
Barriers male.
For proof of 110m height should be l, 067m;
For proof of 200m height should be 0.762 me
For proof of 400m height should be 0.914 m.
Barriers female.
For proof of 100m height should be 0.840 me
For proof of 400m height should be 0.762 m.
Maximum width of barriers: 1.20 m.
Maximum length of the bases: 0.70 m.
Total weight minimum of barriers: 10Kg.
Note: In all cases there is a tolerance of 3 mm plus or minus the standard height for ease of manufacture
barriers.
The width of the barriers - The width of the base should be higher and 70mm thickness between 10mm and 25mm. This bar should
be firmly secured in rods.
The finishing barriers - The upper bar must be painted with white stripes and black, so that when their
ends are white. The barriers should be placed on the floor so that their bases are on the side where
the competitor approaches.
Note: To test the resistance of the barriers should be used a balance spring whose force of attraction is applied in the
center of the top bar. One may also use a hook applied at the center of the upper bar by means of a rope
passes through a pulley by placing weights on the other end of the rope.

All races must be run with lanes, the competitors must remain in their lanes throughout the
route.
