Any judgment in accordance with 8.1.1 and 8.1.2
would normally have an approximate 95 % probability of being correct
however, the precision statistics obtained in this
interlaboratory study (ILS) must not be treated as exact
mathematical quantities that are applicable to all circumstances
and uses. The limited number of laboratories reporting results
guarantees that there will be times when differences greater
than predicted by the ILS results will arise, sometimes with
considerably greater or smaller frequency than the 95 %
probability limit would imply. Consider the repeatability limit
and the reproducibility limit as general guides, and the associated probability of 95 % as only a rough indicator of what can
be expected.
