From the stuffy

vettedudes with matching cap and shirt site;
Getting SURVIVOR® Certified documents the standard for unrestored vehicles. It means that a panel of judges have certified that the car meets these requirements:
*Is over 20 years old.
*Can pass a road test over 20 miles
*Remains over 50% unrestored, un-refinished, or unaltered.
*Retains finishes good enough to use as a color guide for restoration of a car just like it
Judges inspect only four components: Exterior, Interior, Engine Compartment and Chassis. Cars must pass at least three of these four categories in order to become SURVIVOR Certified.

Those standards are extremely lax in my opinion. I don't believe many here would call cars in that category "unrestored"!
