Tool 3.4 Conduct Group Calibration
|Description||Describe the procedures for carrying out a Group Calibration.
Group Calibration is a tool to group calibration demand from users and provide the calibration device through another competent NMI. This tool can be combined with training and development of own capabilities. Concept can last forever or lead to competence in NMI to substitute this service in future.
|Objectives||Provide calibration services to a group of interested companies (group calibration) with the help of an experienced NMI from the region.|
|When to apply||Implementation|
|Requirements||Tool 2.10 Organization of Group Calibration
- For the organizing NMI: Capability to organize and coordinate the group calibration.
- For the subcontracted NMI: Facilities for conducting the calibration (equipment, procedures, trained personnel).
|Resources||Medium to High (for travel expenses)|
|Limits of the tool||Small group of companies can participate due to time limitations in traveling around the country for on-site calibrations or too large number of calibrations in the laboratory.
Costs might be too high due to travel costs for experts and standards.
|Steps||Depend on the two types of application:
- Round trip in the country for on-site calibrations (e.g. balances, test machines)
- Collection of equipments for group calibration in laboratory (e.g. multimeters)
