Helmet standards

[shirt]

yup, the 2002 tethers can be used with 2010 posts so longs as the HANS itself is 2002 and the helmet 2010. Diagram makes it easy.

its either allowed or not, the 'one race' things is both bks, unsafe, and shows they don't know the answer! the photo above is from my own notes for FIA cross country rallies. Our local motorsport authority just lifts this directly from FIA guidelines so your series scrutes should have access to it.

As you were everyone, with the help of google, I've found the above diagram in a current (17/4/19) motorsport UK technical doc and the same with commentary in a 2016 MSA news which explicitly states that both the two valid HANS/tether cominations on the LHS are valid with either of the valid helmet/post combinations on the RHS. I'll print out and laminate both as handy helper sheets for the next scrutineering!

You found that before I did.. how many competitors have been told the same and then spent the money replacing (without any real need).

or, how many competitors don't read the regs?

Same can be said of the Scrutineers! Interestingly, I don't know where you'd look for those specific compatabilities for HANS devices, tethers, posts and helmets. Perhaps you could help as I can't see them in the Blue Book.

The detail isn’t in the blue book. It’s an FIA standard, so you need to go there for the finer points.

And that's not the easiest thing to do in the world. Perhaps "Mr Shirt" can help us.

I'm about to contradict myself massively, but I've never even seen a blue book let alone read one! I compete at low level under ATCUAE but scrutineer FIA cross country rally, F3 and GP2 using their own specific material. I can well sympathise regarding scrute knowledge though, not everyone reads the blurb and the scrute for the series I compete in seems to do all his 'scrutineering' in the time taken to walk across the pit garage floor.


Anyway, if you're racing under the MSA, best print and/or direct them towards their own material:

Details there on the last page. You can also find a full list of FHR compatible helmets here:

Thanks for the reply.

I think I have what I wanted, but your comment made sense. Why not just read the regs! So I went off to find the FIA regs to see where the compatibility is defined and completely failed!

I don't think that the compatibility between helmet and FHR is defined by the FIA because there is no "issue". If it's not a problem, it won't be referenced. The MSA has provided the appropriate clarification (several years ago) and that should be good enough for the officials.
