The National Electric Code (NEC 2002), is the standard for most of the US. Some states and municipalities have adopted modifications to the NEC 2002. You can be generally confident that if you follow NEC 2002, you will be OK.
In NEC 2002, Article 344.30 Securing and Supporting (for rigid metal conduit, or RMC)
RMC is required to be secured at least every 10ft. RMC shall be securely fastened within 3ft of any box. 5ft is acceptable where structural members do not readily permit fastening within 3 ft. Where approved, conduit shall not be required to be fastened within 3ft of the service head for above-the-roof termination of a mast.

at least every 10 ft and within 3 ft of any box. is best to check with your local inspector to see what that city requires.the NEC is only a minimum requirement so some municipalities may require more
