I do not believe the Telecommunications Industry Assn standards address service loops for cabling. BICSI just recommends putting cabling in a figure eight instead of a bid loop. Big loops can degrade category cabling's performance. If a client plans on having a lot of MAC work I would recommend using a Consolidation Point (CP) or a MUTOA (Multi-User Telecommunications Outlet Assembly) in the work area. Also any service loops need to be added in the total length allowed for the cabling (e.g. 295' for a permanent link). MUTOAs also need to be used based upon a formula because of the use of long patch cords.
