That's a great question, and I doubt anyone can answer it except the manufacturer.
Personally if I hadn't "used" it in anger - i.e. crashed on it I suspect it would be fine, BUT foam does die, goes brittle, and loses it's protective qualities, so maybe 7 years is pushing it. I'd especially look for the 1621-2 label - and if it doesn't have it bin it on that principle alone.
Helmets for instance are considered past it at about 5 years maximum.
