Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Response spectrum or curve reported with the agreed units, sample reference and measurement conditions.
Derived optical, magnetic, or acoustic properties supplied in a labelled format suitable for direct sample or condition comparison.
Measurement conditions and comparison notes provided with the processing basis and quality checks agreed during technical review.
Measured result included when selected in the confirmed reporting scope.
Sample requirements
What to provide before work begins
Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.
| Suitable sample | Submission requirement | Planning note |
|---|---|---|
| Solid / component | Provide a clean, stable and clearly labelled specimen with the target face or region identified. | Confirm dimensions, cutting permission and whether the original geometry must be preserved. |
| Powder / particles | Provide a dry, homogeneous and clearly labelled sample in a sealed container. | Exact mass and any drying or dispersion step are confirmed after technical review. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Common planning decisions
Short answers to issues that can change preparation, scope, timing or interpretation.
What should I send for Laser Doppler Vibrometry (LDV)?
Provide solid / component, powder / particles as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Which scope should I choose?
Choose the scope that matches the decision, comparison and reporting depth you need; TESTDOG confirms the final route after technical review.
What will I receive?
Typical outputs include response spectrum or curve, derived optical, magnetic, or acoustic properties, measurement conditions and comparison notes. Final files follow the confirmed reporting scope.
How long will it take?
Typical turnaround is 8 working days after sample acceptance and method confirmation.
