Abstract The impact test for industrial safety helmets in British Standard 5240 concerns only vertical impacts onto the crown of the helmet mounted on an immovable headform. Methods of testing helmets in lateral and vertical impacts were devised involving a crash dummy test with a flexible neck of stiffness equivalent to a human neck, and measurement of the rotational acceleration of the head. Overall, the tests showed that the current BS 5240 impact test and its criteria for injury are unrealistic. Provision for side impact tests would lead to improvements in helmet designs.
