Traceability Example for Secondary Method 11 NMI: calibrates Master Reference FCAE Calibration lab: uses ISO 27891, PMP requirements and Master Reference FCAE to calibrate multiple Reference CPCs with desired particle material(s), sizes and concentrations NMI: provides traceability of particle size standards Calibration benches for PMP: use ISO 27891, PMP requirements and Reference CPCs with desired particle material(s) to calibrate CPCs If the NMI can provide calibration of Reference CPCs with the desired particle material, the Master Reference FCAE may become obsolete for the secondary PMP method.
