What Alteburger said. There are designed speed limits for the charted procedures if it complies with Pans Ops procedures.
Speed is specified in the Pan Ops criteria for the category of aircraft. Required max speeds are defined by the approach point ie initial approach etc.
There is a wealth of info on the jeppesen site regarding this stuff and more.
General Aviation IFR Chart Clinic - Jeppesen Supplies and look under the chart clinic reprints.
