The method, preparation route and reporting depth depend on what you need to decide.
Standard thermal scan
thermal transitions, stability, heat flow, expansion, conductivity, or temperature-dependent behaviour
- Best used when
- thermal transitions, stability, heat flow, expansion, conductivity, or temperature-dependent behaviour
- Typical result
- Temperature-dependent curve
- Preparation note
- Exact mass and any drying or dispersion step are confirmed after technical review.
Controlled-atmosphere or temperature programme
differences between materials, batches, treatments, or service conditions
- Best used when
- differences between materials, batches, treatments, or service conditions
- Typical result
- Transition or thermal-property values
- Preparation note
- Confirm dimensions, cutting permission and whether the original geometry must be preserved.
Kinetic, modulated, or comparative analysis
whether the measured result supports a specification, root-cause, or development decision
- Best used when
- whether the measured result supports a specification, root-cause, or development decision
- Typical result
- Test programme and interpretation notes
- Preparation note
- State the substrate, nominal thickness and whether sectioning or mounting is permitted.
Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Temperature-dependent curve reported with the agreed units, sample reference and measurement conditions.
Transition or thermal-property values supplied in a labelled format suitable for direct sample or condition comparison.
Test programme and interpretation notes provided with the processing basis and quality checks agreed during technical review.
Method-specific images 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 |
|---|---|---|
| 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. |
| 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. |
| Film / coating | Provide the coated substrate or a flat film with the test surface and coating side clearly marked. | State the substrate, nominal thickness and whether sectioning or mounting is permitted. |
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 Vicat Softening Temperature / Heat Deflection Testing (Vicat/HDT)?
Provide powder / particles, solid / component, film / coating 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 temperature-dependent curve, transition or thermal-property values, test programme and interpretation notes. Final files follow the confirmed reporting scope.
How long will it take?
Typical turnaround is 7 working days after sample acceptance and method confirmation.
