Final functional verification is the point where the completed DVS-G is evaluated as an assembled instrument. It complements component traceability and supplier documentation by confirming that the finished gauge performs its intended vacuum-holding function before release.
Supplier documentation supports incoming-component quality. Final DVS verification checks the completed instrument after assembly.
Why final verification matters
A component can arrive with acceptable supplier documentation and still become part of an assembly that needs final checking. Connections, fittings, seals, assembly steps and handling can all affect the finished product.
Final verification provides a last quality checkpoint before the gauge is released for shipment.
What the functional check is intended to verify
Each assembled gauge is functionally tested to verify that it maintains vacuum for a defined test duration prior to final release.
The finished DVS-G is evaluated after the instrument has been assembled.
The gauge is checked to verify that it maintains vacuum during the defined test period.
Verification occurs before the instrument is released as a finished product.
The result becomes part of the quality record associated with the serialized gauge.
How it fits with component traceability
The DVS-G quality record connects a serialized sensor assembly to the serial number of the finished gauge. Final functional verification adds another layer by documenting that the completed instrument was checked after assembly.
Together, these records provide a clearer product history than either component documentation or final testing would provide on its own.
Functional verification is not the same as calibration
A functional vacuum-retention check and a calibration procedure serve different purposes. Functional verification evaluates whether the assembled unit performs the intended check defined for final release.
Calibration, where required, typically involves comparison against defined reference standards and documented measurement conditions. Customers should confirm any calibration requirements associated with their own process or quality system.
Documented release
Final verification supports the release record for the finished DVS-G. Depending on the product record and purchasing requirements, the retained documentation may include the finished gauge serial number, serialized component information, supplier COC, functional verification record, signature and date.
- Finished DVS-G serial number.
- Associated serialized sensor assembly.
- Supplier Certificate of Conformance.
- Final functional verification.
- Applicable release signature and date.
The role of final verification in a quality-sensitive environment
For manufacturers working in aerospace, defense, space and other quality-controlled environments, documentation often matters nearly as much as the physical instrument. A defined final verification step helps show that the completed gauge was not released solely on the basis of incoming component documentation.
It also provides a documented checkpoint that can be referenced later if the instrument's build history is reviewed.
Program-specific requirements for calibration, approval, certification, acceptance testing or instrument control remain the responsibility of the applicable customer and governing process documentation.
