Assessing competence
Option 1 :
Use of Formal External Recognition
Option 2 :
Assessment of external laboratories competence by licensee

Accreditation to ISO17025
Need to consider:
n Scope of Accreditationn Parameter, units of measurementn Matrixn Method usedn Limit of quantitationn Uncertainty of Measurementn Fitness for Purposen Sampling/sample integrity
