17 Page 17 INF GR / PS / 5 th Meeting INF GR / PS JapanOttawa, Canad, Sep Page 17 INF GR / PS / Effective Head Mass at Impact Effective head mass varies significantly according to the impact conditions such as vehicle shape, stiffness, walking stance and so on. Average effective head mass ≒ Head mass Adult head: 4.5 kg (Ref. IHRA/PS150, ISO/N354) Child head: 3.5 kg (Ref. IHRA/PS178, SAE973317) * 3-Year Child Head Mass = 2.7 kg * 6-Year Child Head Mass = 3.5 kg * 5 th % Adult Female Head Mass = 3.6 kg
