If you unlock a weapon via certifications that it will be available to any class that can use it, on the character who earned the certifications. It wont be available to any other character on your account.

I have just confirmed this using two VS alts that I have. On the first one I purchased the Sirius SX12 SMG for certifications and was able to equip it on both of it's Infiltrator and Light Assault classes. When I logged into my second VS alt, the Sirius SX12 was still locked.
