The 10,000 is a standard track event and world records are kept on it. This is where you see most of the top level marathoners come from. Other than wind and elevation where the meet is held, it is a lot more consistent as far as what times you can expect the top runners to do.
A 10k is a road race and times can be all over the place based on road conditions, course layout, weather, etc.
To put it another not-so-nice way. A 10k is for weekend warriors. The 10,000 is for serious track athletes.
Actually, a 10km road course should be a minimum of 10,010m long…
Actually, a 10km road course has to be a minimum of 9,990 m long. Last I remember they give 1 in 1000 error.
Edit: I remember this because when the world record was set at the Crescent City Classic around 1984 they had to re-certify the course and it made it by 1 meter (9991).
Results: In either a pre-race or post-race validation, the course passes if the validator’s measurement finds it to be at least the nominal distance; it fails if the validator’s measurement finds it to be less than the nominal distance. Remember that the original certification measurements will have included the SCPF. Therefore, in a perfect world, the validator ought to find the nominal distance plus SCPF. For example, in checking a 10 km course, the validator should find 10,010 meters. If the validator finds less than 10,000 meters, the course Fails. Note: If the original measurements for certification were done by two measurers who have IAAF Grade A or Grade B status, and if those measurers used standard certification procedures including the SCPF, the course may be considered pre-validated. For such pre-validation status to apply, a report of the original certification measurements must be filed with the RRTC Validation Chair including all data related to the measurements along with a narrative and map. Consequences of Passing or Failing Validation: If the Course Passes: The course will be regarded as having the correct length for record purposes, meaning that records can be accepted if the course is used as measured in the validation and if all other requirements for a record performance are satisfied. No further adjustment to the course is required, and in particular, the course should not be shortened. Any shortening of the course would require a new certification and would lose its status of having passed validation. If the Course Fails: If it’s a post-race validation, then any pending records that prompted the validation will be rejected. If it’s either a pre-race validation or a post-race validation in which the course being validated matched the course originally certified, the original certification is nullified. To obtain a new certification, the validator’s measurement may be used as one of the required measurements, but at least one additional measurement, by either the validator or some other person, is required. Since these measurements will then be considered as part of a certification process, the SCPF must be used. Following a re-certification done this way (using the validator’s ride as one of the measurements), the course will be considered pre-validated.

So a 10km World record can be short of 10km’s and still be a WR?

Interesting. Just curious – what is the source?
I didn’t notice at first the year you were referencing. They actually changed the certification rules for courses at the end of 1984. Prior to that, courses had a +/- tolerance. Now, they don’t. So that explains why that record was on a “short” course.
All you really did was out yourself as an American (as if your signature didn’t give it away already). For all the non U.S. people who post here, including presumably the OP, that’s not even a joke. They just see it as you misunderstanding the punctuation. I fulfilled my patriotic duty to try to laugh at a joke of a fellow citizen but nothing came out.
