Standard Interpretation

Standard: 2016
Section: V1M4, Section (k)


k) The laboratory shall use and document a measure of relative error in the calibration.

i, ii-a and ii-b discuss running calculations on the calibration standard results used in the curve.

For metals analysis, we use ICP/ICPMS and a zero point and single calibration standard, which makes it impossible to calculate %RE or %RSE of a mid point and low level calibration standard. We are interpreting the standard to read that when a zero point, single calibration standard is used, the requirements of do not apply and are replaced by the requirements in the next paragraph - section (which specifically discuss requirements for single point calibrations.)

Please confirm that we are interpreting these requirements correctly.


Your interpretation is confirmed as correct.
