It depends on what you are testing. The test you are quoting for for viral assay. Functioning, able to reproduce virus. The longer test was looking for RNA on surfaces, not necessarily functioning virus.
Different standards.
Plus temperature makes a big difference. The colder, the longer it remains potent. Apparently above 45-50 C, it denatures.
