SCHEDULE 1 REGULATION 12 3.3.4 Ventilation It is the manufacturer’s responsibility to provide for adequate ventilation in the headgear design. 3.3.5 Retention System The retention system should be attached so that the headgear remains in its normal position during play. The chin strap that secures the headgear should be affixed to both sides of the headgear and pass under the lower jaw in close proximity to the jaw and the neck. The minimum width of the chin strap shall be 15 mm. Buckles or similar hard fixings may not be used. Rubber buttons or Velcro® type fixing materials are acceptable. 3.4 Performance Requirements 3.4.1 Impact Attenuation When tested in accordance with the procedures specified in Section 4.3, the peak acceleration of impacts delivered to test locations shall not be less than 200g. 3.4.2 Retention System Strength When tested in accordance with Section 4.4, the strap should stay intact and closed when loaded with a 7 kg mass but should fail when strained dynamically by an additional mass of 10 kg allowed to fall through 300mm. 3.4.3 Retention System Effectiveness When tested in accordance with the procedures specified in Section 4.5 the headgear may shift but not roll off the wearer’s head when initially subject to a static load of 3 kg followed by an additional dynamic load exerted by a 4 kg load falling through 175mm. 4. Test Methods and Procedures – Headgear 4.1 Sampling Three (3) test specimens of each size shall be submitted by Manufacturers, complete with ‘Information supplied by the Manufacturers’ (see section 9). Two specimens shall be used for impact attenuation testing at the various conditions and one for retention system testing. 4.2 Conditioning of Specimens Prior to impact testing, one specimen will be exposed to ambient conditions and another to high temperature conditions as follows: (i) Ambient Temperature - one sample is conditioned by exposing it to a temperature of 20°C +/- 2°C and relative humidity condition of rh60% +/- 5% for a period of between 4 and 24 hours.
