9. RELATIONSHIP TO OTHER METHOD PRINCIPLEs
Instruments with specific instrument-dependent methods which
do not fall within the tolerance limits of this ECCLS s t an–
dard Method may nevertheless be able to produce numerically
equivalent results by a calibration process.In such cases the
manufacturer should document that the methods fulfill the
performance criteria given.in 2.1 of these ECCLS standards.
The validatian of calibration of enzyme methods is discussed
in ECCLS Reference Enzyme Materials, Draft 2, 1987 (9).
