53 FACILITIES GUIDE | JUNE 2020 LIGHTING STANDARDS Some National Associations and governments have set different requirements for indoor or outdoor lighting and may use different units of measurement. However, as a guide, the following shows the minimum standards according to the European Standard for Sports Lighting (EN 12193:2008) where: • Class I: Top-level national and international competitions (non-televised) with requirements for spectators with potentially long viewing distances. • Class II: Mid-level competition, such as regional or local club tournaments. This generally involves medium-sized numbers of spectators with average viewing distances. High-level training may also be included in this class. • Class III: Low-level competition, such as local or small club tournaments. This does not usually involve spectators. General training, school sports and recreational activities also fall into this class. LIGHTING RECOMMENDATIONS 5.1 General recommendations Reference area The Total Playing Area (TPA), for which the following lighting requirements are defined, includes the Principal Playing Area (PPA) and extends to a perimeter of 1 m inside the perimeter of the court. Reference grid for calculation and measurements Calculations and measurements of the performance of a lighting installation should be done on a specific grid, where grid points are determined by the length and width of the TPA. For horizontal illuminance the reference level of the grid is the ground. For calculation, it is recommended to define a grid of 15 points along the length direction and seven points along the width direction of the TPA, with a grid spacing of 2.5 × 2.5 m. Measurements can be done by using only one point out of two, on 5.0 × 5.0 m spacing (see Fig. 3).
