Abstract: | The agreed purpose of an inter-laboratory certification study is to characterise a certified reference material (CRM). In
addition to this, any (successful) certification study may also be utilised as a laboratory/method performance study by the
participants. The intention of this note is to emphasise the complementary use of certification study data by the participants
of the certification study and to explain the options involved. On this occasion, an apparent paradox arising in the interpretation
of certification study data is resolved. The procedures for bias correction and estimation of bias-related uncertainty contributions
discussed on this occasion are, however, generally applicable to normal CRM use.
