Single-condition measurement
density, transport, rheological, dimensional, moisture, or other bulk physical properties
- Best used when
- density, transport, rheological, dimensional, moisture, or other bulk physical properties
- Typical result
- Measured property values
- Preparation note
- Exact mass and any drying or dispersion step are confirmed after technical review.
Temperature, rate, or environment sweep
differences between materials, batches, treatments, or service conditions
- Best used when
- differences between materials, batches, treatments, or service conditions
- Typical result
- Condition-dependent curves
- Preparation note
- State the substrate, nominal thickness and whether sectioning or mounting is permitted.
Comparative or specification-based programme
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
- Method, uncertainty, and comparison notes
- Preparation note
- Declare volatility, corrosivity, suspended solids and any storage or temperature requirement.
Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Measured property values reported with the agreed units, sample reference and measurement conditions.
Condition-dependent curves supplied in a labelled format suitable for direct sample or condition comparison.
Method, uncertainty, and comparison notes provided with the processing basis and quality checks agreed during technical review.
Measured response curves 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. |
| 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. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
| Gas / headspace | Provide the gas composition, concentration range, cylinder or sampling format and required pressure. | Gas compatibility, fittings, flow and safety controls are confirmed before acceptance. |
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 Membrane Electrode Performance Testing (MEA)?
Provide powder / particles, film / coating, liquid / solution, gas / headspace 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 measured property values, condition-dependent curves, method, uncertainty, and comparison notes. Final files follow the confirmed reporting scope.
How long will it take?
Typical turnaround is 15 working days after sample acceptance and method confirmation.
