Default Re: Helmet BIS standards revised; now lighter, airier

Such a ridiculous change to make.

Especially the 1.2kg weight limit.


I've filed an RTI for now.

Not sure if the phrasing is correct, but here it is:

Quote:
Recent news articles are stating that the maximum weight for helmets is being reduced from 1.5kg to 1.2kg.

Sources:
1) https://auto.ndtv.com/news/bis-intro...elmets-1889488
2) https://timesofindia.indiatimes.com/...w/65096591.cms

I would like you to:
1) Produce the scientific analysis/research that proves helmets weighing above 1.2kg are unsafe
2) Explain why there is no minimum weight limit

I'm very curious to know if they have a curve of safety vs weight. In which case, they should have one peak in the curve where safety is highest. If so, all helmets should be that exact weight! Absurd.

The FIA recommends a maximum weight of 1.8kg for their full-face helmets. (FIA is the association that regulates Formula 1)

The median weight of 271 world-class full-face helmets is 1643g.

If FIA could set a limit of 1.8kg considering racing teams have access to carbon fiber and if world-class helmets weigh around 1.6kg, how on earth did we conclude 1.2kg to be the maximum limit?

Or was it a certain MetalAvian at work?

Govt to notify new standard for heavier helmets for bikes.

Quote:
This will be in addition to the already notified standard for helmets that can weigh up to 1.2 kg and meet the prescribed norms, though the implementation date of this has been extended twice.

Government to bring in newer norms for Premium Helmets in India

Source: http://overdrive.in/news-cars-auto/g...mets-in-india/

From the article, it seems like there will be a newer standard for the premium helmets which are heavier than the existing 1.2 Kg limit and the manufacturers has to adhere to this new standard. However, it's not clear whether these imported helmets has to be get BIS re-certification in order to be sold in India.
