OIML R126 is the International Standard for Evidential Breath Analyzers

Purpose:
To obtain admissions that:
there exists an international legal measurement standard for evidential breath analyzers
the International Standard for Evidential Breath Analyzers is OIML R126
that OIML R126 is the international standard referred to by Brian Hodgson in his paper
that Canada is a member state of OIML
that Canadian scientists have played a role in the development of this international standard
that the international standard does not state that one control test data point is adequate to check the reliability of evidential breath analyzers
to introduce the concept of MPE or "maximum permissible error" at low, medium, and high data points, such as 50, 100, 300 mg/100mls
to consider the different applications of MPE at each of: type approval, initial verification of the specific instrument, verification after repair, all contrasted with at time of subject tests.
