REGULATION 12 SCHEDULE 1 edges, seams, buckles or other items on the surface of the product that could harm the wearer or other players during normal use. 3.3 Design 3.3.1 Zones of Coverage The headgear must have zones of coverage that cover the crown, temple, forehead (sweatband area) and ear areas. The zones of coverage shall fulfil the requirements of the impact performance specification (Section 3.4.1) and have a maximum padding thickness of 10mm+2mm tolerance band plus an additional allowance of 1mm on each side for fabric. The typical dimensions of the zones of coverage are given in Table 1. Areas outside designated zones of coverage do not have to meet impact requirements but must be of soft foam or leather and be less than or equal to 5mm in thickness. Where this overall thickness consists of padded material covered by fabric, 0.5 cm is the maximum measured thickness for the combination of the uncompressed padding and the fabric. The fabric can contribute up to a maximum measured thickness of 1 mm on each side of the padding. All padding materials must have a density not greater than 45 kg/m3 + 15 kg/m3 tolerance band.
