![]() ![]() The Head Injury Criterion or HIC score is an empirical measure of impact severity based on published research describing the relationship between the magnitude and duration of impact accelerations and the risk of head trauma.Two test methods shall be used to determine the impact attenuation of a playground surface or surfacing materials: critical fall height test, and installed surface performance test. G-max is the measure of the maximum acceleration (shock) produced by an impact. The test method quantifies impact in terms of g-max and Head Injury Criterion (HIC) scores. This specification specifies impact attenuation performance requirements for playground surfaces and surfacing materials and provides a means of determining impact attenuation performance using a test method that simulates the impact of a child’s head with the surface.
