The registration is closed – this training course is fully booked.
Objective
The training aims in improving the knowledge of the laboratory staff in EURAMET NMI/DIs on maintenance of primary mass standards and the calibration of mass standards to OIML Class E1 level uncertainties.
The course objectives are for participants to:
- Become familiar with mass scale
- Understand traceability in the mass area
- Understand the different weight classes
- Become familiar with good practice in weight inspection, handling and calibration
- Carry out ABA and ABABA calibrations
- Understand buoyancy corrections and how to apply them
- Carry out balance assessments
- Understand and produce uncertainty budgets for mass calibrations
The course will comprise a mixture of approximately 1 ½ days of formal lectures and 1 ½ days of practical sessions.
Who should attend
Mass metrology staff from EURAMET NMI/DIs who are less experienced in mass calibration at the OIML E1 level of uncertainty. Participants are expected to have basic knowledge of mass measurements.
