For many carriers it's not simply a matter of standing orders but of
governmental regulation.  For US carriers, FAR 121.565(a) applies:

   Section 121.565 Engine inoperative: Landing; reporting

   (a) Except as provided in paragraph (b) of this section, whenever an
   engine of an airplane fails or whenever the rotation of an engine is
   stopped to prevent possible damage, the pilot in command shall land
   the airplane at the nearest suitable airport, in point of time, at
   which a safe landing can be made.

   (b) If not more than one engine of an airplane that has three or more
   engines fails or its rotation is stopped, the pilot in command may
   proceed to an airport that he selects if, after considering the following,
   he decides that proceeding to that airport is as safe as landing at
   the nearest suitable airport:


While not pertinent to ETOPS, the conditions enumerated under
paragraph (b) include obvious ones such as weather, terrain, weight,
etc.  Remaining paragraphs of the section deal with reporting.
