Those ratings are the minimum safety standards your helmet must meet to be legal and get through scrutineering. It must match one of them. i.e. snell 2005 or 2 BS6658 - 85 Type A FR.
There will be a sticker inside if it does, so you can check. You'd also know as you'd have bought it from a place that sells track/racing helmets. Pikey karting/bike helmets aren't up to the job and are not fire resistant which is mandatory.
Do you not need your ARDS race license to do this race?!?! To pass the exam you'd already know these things. You'll also need fireproof race suit/boots/underwear etc.
