Calibration Standards¶
Calibration standards document the reference standards and reference instruments used during a calibration. Traceability to recognized standards is a central requirement of ISO 17025.
Overview¶
One or more standards can be assigned to each calibration operation. The standards reference inventories that are maintained as reference standards in the system.
Columns¶
| Column | Field | Description |
|---|---|---|
| Inventory Number | C2430 | Inventory number (MTAG) of the reference standard used. |
| CTAG | CTAG | Unique identifier of the associated calibration operation. |
| MTAG | MTAG | Inventory number of the calibrated device. |
| Device Identifier | I4201 | Internal device identifier of the reference standard (from inventory). |
| Manufacturer | I4202 | Manufacturer of the reference standard (from inventory). |
| Model | I4203 | Model designation of the reference standard (from inventory). |
| Serial Number | I4204 | Serial number of the reference standard (from inventory). |
| Next Calibration | duedate | Due date of the next calibration of the reference standard. |
The columns I4201--I4204 are automatically displayed via the link to the inventory and are filterable.
Typical Workflows¶
- Assignment During Calibration: When creating a calibration, the reference standards used are assigned as standards.
- Traceability: Through the link to the inventory, the complete calibration chain from the reference standard to the national standard is traceable.
- Validity Check: The system indicates whether the calibration of the reference standard was valid at the time of use.
Technical Notes¶
Inventory Link
Standards reference existing inventories in the system. The field C2430 contains the inventory number (MTAG) of the reference standard.
Validity Check
Expired or uncalibrated reference standards can compromise the validity of the performed calibration. Regularly check the calibration status of the standards in use.
- The assignment is made per calibration operation (CTAG) and calibrated device (MTAG).
- Standards can be added or removed via the calibration detail view.
- Deletion requires the
inventory_details_calibrations_standards_deletepermission. - The display is configurable via the field management.
