The MAUR requirements are the same for all five planes. Each plane should be considered separately.

In the example below, reference point 69 is considered on the vertical plane for a level C stadium.

Level C stadium – MAUR evaluation

Reference point 69 on the 270° vertical plane

Reference point 69 – Ev-270° = 1,548 lux

MAUR >0.50

Illuminance values lower than the primary reference point:

The illuminance value at the secondary reference points 57, 70, 81 and 68 on the 270° vertical plane must be greater than:

1,548 x 0.50 = 774 lux.

Illuminance values greater than the primary reference point:

The illuminance value at the secondary reference points 57, 70, 81 and 68 on the 270° vertical plane must be lower than:

1,548 x 1.40 = 2,322 lux.

MAUR for UEFA elite level A

For a pitch illuminance system to meet the UEFA elite level A lighting requirements, there must be no more than 10 MAUR failures throughout the whole pitch.

Note - The total number of MAUR failures for each UEFA lighting category is determined by calculating the total number of failures across all 96 reference points for each of the five reference planes.
