SCHEDULE 1 REGULATION 12 Figure 4. Typical apparatus for Impact Testing of Headgear 4.3.3 Reference Testing A flat MEP (modular elastomer programmer) reference surface will be used measuring 150mm diameter, 25mm thick mounted on a matching steel base. The headform will be dropped onto the MEP impact surface from a distance 300mm +/- 5mm. Resolved gmax values recorded by the accelerometer on three successive drops shall lie within +/- 10g of the mean. 4.3.4 Impacting The headgear is matched for best fit to the testform according to the manufacturers recommendations. Each headgear is impacted where additional padding has been applied within the specified zones of coverage (crown, forehead and temple/sweatband areas). An energy level of 13.8J will be used for impact. This is equivalent to the ‘J’ headform falling through 300mm. The height of fall will be adjusted for each headform mass. Note: Mass of headforms used are A - 500 mm - 3.1Kg ± 0.10 M - 600 mm - 5.6Kg ± 0.16 E - 540 mm - 4.1Kg ± 0.10 O - 620 mm - 6.1Kg ± 0.18 J - 570 mm - 4.7Kg ± 0.14 Last update: 14 January, 2015 200
