Your cache administrator is webmaster. Difference Between Precision And Uncertainty Volumetric flask is used to dilute original sample to known volume, so it is paramount that it contains exact volume. Note that ASTM standards, while adopted worldwide, may be different from your national standards.

The error in judging the reading is therefore bigger that the error from the stop clock.
