This is not a direct answer to your question but my humble experience is that when you receive these jobs, you almost always get a list of ‘deliverables’ … setting out exactly what you are required to deliver in terms of level, format etc. I you don’t, it can be a very good idea to ‘ask’.
It is not always safe to assume that the delivery spec will be what you expect it to be. There might well be a ‘broadcast standard’ but it does not necessarily follow that this is what you will be required to deliver to the broadcaster/network.
