Helmets save lives. That is not a marketing line, it is the reason the Government of India made BIS certification for helmets mandatory. Every helmet sold in India, whether made locally or imported from abroad, must carry the ISI mark under IS 4151:2015 before it can legally reach a consumer, and since January 1, 2026, every new two-wheeler sold in the country must come with two BIS-certified helmets included by the dealer, one for the rider and one for the pillion. Demand has surged as a result, and so has enforcement: the government has already cancelled or let lapse over 160 manufacturing licenses in 2026 alone for non-compliance.
If you are a helmet manufacturer, importer, or brand owner trying to understand how to get a BIS certificate for a helmet, what the testing process involves, how much it costs, and what documents you need, this page covers everything you need to know, clearly and completely.
IS 4151 is the Indian Standard for Protective Helmets for Scooter and Motorcycle Riders. It specifies the construction, performance, and testing requirements that every certified helmet must meet.
The standard covers the following key areas:
| Test | What It Checks | Method |
|---|---|---|
| Impact Attenuation Test | How well the helmet absorbs shock during collision | Helmet dropped onto a flat anvil and a kerbstone anvil from specified heights |
| Penetration Test | Whether a pointed striker penetrates the shell | Pointed striker dropped from prescribed height onto helmet |
| Retention System Test | Strength and stretch of chin strap | Load applied to chin strap; stretch and breakage limits checked |
| Retention System Effectiveness | Does the helmet stay on during an accident | Dynamic test simulating helmet coming off during impact |
| Field of Vision Test | Does the helmet restrict rider's view | Measurement of horizontal and vertical fields of vision |
| Surface Friction Test | Does the helmet snag during a slide | Rotational impact test on oblique surface |
| Visor Optical Quality | Is the visor clear and non-distorting | Visual and optical tests on visor material |
The total cost of obtaining BIS certification for helmets under IS 4151 includes several components. Here is a breakdown :
