Low Temp Bolting

[Ian63]

What are the low temperature (-30 deg C) effects on ISO 898.1 Grade 8.8 bolts? ISO898.1 specifies a charpy impact strength of 30 J when tested to ISO 83, which I assume is conducted at a low temperature, but I don't know what that temperature is though. Any advise would be a great help.
