ICAO PANS-ATM DOC4444 5.4.1.1.1 refers to a "separation buffer" to which navigation tolerances are added:
"Lateral separation shall be applied so that the distance between those portions of the intended routes for which the aircraft are to be laterally separated is never less than an established distance to account for navigational inaccuracies plus a specified buffer. This buffer shall be determined by the appropriate authority and included in the lateral separation minima as an integral part thereof."
The Australian MOS Part 172 10.8.1.1 defines that buffer as 1NM:
"
10.8.1.1 The Lateral Separation buffer is 1NM between the possible positions of two aircraft. (ICAO PANS-ATM, Chapter 5.)"
