What are the standard criteria that apply to all IFR departure procedures?

The standard criteria that departing aircraft will adhere to in order to assure obstacle clearance include:

1. Cross the departure end of the runway at or above 35ft
2. Make no turns until 400ft AAE (above aerodrome elevation)
3. Maintain a climb gradient of 200ft per NM until the en-route structure is reached – unless otherwise stated.
