doughie - 6/8/06 at 06:40 PM

Hi

have tried serachin to no avail

can any one let me know the minimum diameter of a roll bar to satisty mr SVA?

DIY Si - 6/8/06 at 06:42 PM

I've heard various versions, either 1.5"/37mm or 1.3/4"/44mm

No roll bar needed for sva

the only reference to roll bar thickness/diameter in the sva manual is relating to recomended seat belt achorages. if you dont have one you just need to mount the seat belt somewhere else.

will be looking to fix four points to chassis...


with the roll bar - thinking there is a minimum diameter - - mine is 45mm????


ta for all your replies

Roll bar is not needed for SVA so no minimum diameter or thickness or material specification or colour or anything. If you fit one it will be tested for edge radius compliance.

I thought it depended upon how it was fixed, ie if welded it becomes structural and as such has to suitable for the application. But if bolted its cosmetic.

nope the same reason they dont need to measure the output on the flux capacitor, because you dont need one.

As pete says, the terminals on the flux thingy still need to be radiused.

As stated "no requirement", but if you bolt one on the SVA inspector will check that the bolts are at least 8mm dia, and that they are marked 8.8 or better. Regards Ray

Atleast 11mm diameter!!!! Or 7/16ths.

Cheers,

yea, normal "safety" anchorage bolts are always based on 7/16" UNF (no idea why!)

And that's even standard in the rest of the world!
It's coming from UN-standard regulation

Now you know

James, I hate to say this, seeing as how I have now met you and feel you are a nice guy, . But you are wrong!!! it's the seat belt anchorages that need to be 11mm/7/16" or better, the roll bar fixings need to be "at least 8mm x 8.8's" or better. Read the SVA manual. Regards Ray.

No, I was right, it's just that we were talking about different things!

As you say, I misunderstood, and was talking about the seat belt bolts, not the rollbar to chassis bolts!

Sorry for the confusion!

ta for all of the advice - so i'll be ok with the 45mm diam roll bar (it's welded on)
