Headforms for use in the testing of protective helmets
Served as the foundational draft for both IS 7692 and EN 960, defining the original geometry and dimensions.
Key Differences
≠IS 7692 specifies 6 headform sizes (A, E, J, K, M, O), while EN 960 and ECE 22.06 offer a more granular range with different letter designations for some circumferences (e.g., a 600mm head is 'M' in IS 7692 but 'K' in EN 960).
≠The specified mass for equivalent headform sizes differs significantly. For a 570 mm headform (Size J), IS 7692 requires 4.7 kg, EN 960 requires 5.0 kg, and the more recent ECE 22.06 requires a heavier 5.6 kg.
≠The material resonance requirement in IS 7692 is 'no resonance below 3000 Hz', which aligns with ECE 22.06, but is less strict than EN 960:2006, which specifies 'no resonance below 5000 Hz'.
≠IS 7692 is a standalone specification for headforms, whereas in standards like ECE 22.06 and ANSI Z89.1, the headform specifications are an integral part of a larger helmet performance standard.
Key Similarities
≈The fundamental geometry and shape of the headforms in IS 7692 are very similar to those in EN 960, as both are based on the withdrawn ISO/DIS 6220 draft standard.
≈All standards recommend a low-resonance metal, such as magnesium alloy, as the primary material for the headform to ensure testing consistency and durability.
≈IS 7692, EN 960, and ECE 22.06 all require the headforms to be clearly marked with reference planes (Basic, Reference) and axes (longitudinal, vertical) for accurate and repeatable helmet positioning.
≈All compared standards permit the use of laminated hardwood (e.g., beech) as an alternative material to metal, provided it meets the necessary dimensional and performance criteria.
