Lid Question

[Matt]

OK, So I get the gist of the rules - BS something or another or equivalent.

So what about EN966? e.g. An open face microlight helmet?

[CB1]

Wont meet the rya rules Matt.

No open face helmet meets the rules, as the definition for the helmet standard used is a full face definition. You can ask the manufacturer for an equivalency statement for an open faced helmet. That is what I had to get.

[Matt]

Is this cos EN996 is inferior to BS6658B, or some other reason I've missed?
