Upon completion of this course, you will be able to:
- Outline the scope of <41>
- Understand the risk-based approach for qualification activities (calibration, performance checks)
- Explain the requirements of assessing balance performance according to <41>
- Understand the requirement of calibration and determination of measurement uncertainty
- Perform the repeatability assessment
- Calculate the minimum weight of analytical balances
- Understand the difference between minimum weight and smallest net weight
- Perform the accuracy assessment
- Outline the scope of <1251>
