- Preparation note
- Exact mass and any drying or dispersion step are confirmed after technical review.
Cyclic or accelerated ageing programme
differences between materials, batches, treatments, or service conditions
- Best used when
- differences between materials, batches, treatments, or service conditions
- Typical result
- Pre/post performance comparison
- Preparation note
- Confirm the applicable standard, dimensions, loading direction and number of replicates.
Pre/post comparison with functional or analytical checks
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
- Failure observations and acceptance summary
- Preparation note
- Confirm power, connections, operating state, access restrictions and permitted disassembly.
Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Exposure log and condition record reported with the agreed units, sample reference and measurement conditions.
Pre/post performance comparison supplied in a labelled format suitable for direct sample or condition comparison.
Failure observations and acceptance summary provided with the processing basis and quality checks agreed during technical review.
Exposure record 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. |
| Test coupon / specimen | Provide labelled specimens prepared to the agreed geometry, orientation and surface condition. | Confirm the applicable standard, dimensions, loading direction and number of replicates. |
| Device / assembly | Provide a complete labelled device or assembly with drawings, interfaces and operating limits. | Confirm power, connections, operating state, access restrictions and permitted disassembly. |
| 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. |
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 Smoke Density Testing?
Provide powder / particles, test coupon / specimen, device / assembly, solid / component 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 exposure log and condition record, pre/post performance comparison, failure observations and acceptance summary. Final files follow the confirmed reporting scope.
How long will it take?
Typical turnaround is 7 working days after sample acceptance and method confirmation.
