Hardware buying guide
Start with the question the test must answer. Share the intended use, known failure modes, and the evidence needed for the next product decision.

Build a testing brief →03 / Compare
Compare test conditions, sample counts, preparation, reporting, and retest scope. Ask whether the planned work is exploratory testing or evidence for a specific requirement.
Compare provider details →State whether the work investigates a failure, compares designs, checks a customer requirement, or supports a formal assessment. Each purpose changes the samples, method, operating conditions, and reporting you need. Put the decision and its owner in the request before asking for a lab slot.
NIST explains that laboratory accreditation concerns competence for specific tests or calibrations and is documented by a scope. Where accredited work is needed, check the selected location and method against the current scope rather than accepting an organization-wide claim.
Use these evidence requests to resolve the project scope before ordering.

| Question | Evidence to request | Needs clarification |
|---|---|---|
| Can the proposed site perform the method? | Named facility, equipment envelope, and applicable scope where required. | An accreditation logo with no location or method confirmation. |
| Will the setup represent our product? | An agreed fixture, operating state, and measurement arrangement. | A lab booking is offered before sample and setup needs are understood. |
| What evidence will the report contain? | Defined results, conditions, deviations, and sample identification. | Only a pass/fail summary is offered when investigation needs data. |
Illustrative project: a powered sensor must keep logging during an environmental trial. Specify the enclosure revision, mounting arrangement, power, software, and logging check. Ask the lab how it monitors the unit during the run and records interruptions. If a failure occurs, preserve the setup and timeline in the report before changing the design or scheduling a retest.
No. Accreditation concerns a lab's competence within a defined scope. Ask separately what product assessment or certification, if any, the engagement delivers.
Agree the sample plan with the test owner and lab based on the objective or applicable method. Record spares, destructive work, and whether the same sample is used across tests.
Review the conditions, sample, and failure evidence before deciding on a design change. Agree which checks must be repeated and how the new report relates to the earlier result.

Documented service scope
These records have an official capability source. Details may cover one service within a provider's wider offering; confirm the process and material combination for your project.
Processes: Mechanical testing, Nondestructive testing, Chemical analysis, Environmental testing, Metallurgical analysis
Scope and buying questions: Specify the specimen, material, acceptance standard, and whether the test is destructive. Which preparation, sampling, and traceability records are required? Confirm the laboratory and current method scope, and distinguish routine testing from an investigation of a field failure.
Official capability source →Processes: Battery testing, Testing and conformity assessment, Certification services
Scope and buying questions: Identify the battery or product configuration and the exact laboratory. Which electrical, mechanical, or environmental tests are proposed? Request the applicable standard and report scope rather than assuming every service applies at every DEKRA site.
Official capability source →Processes: Vibration testing, Shock testing, Environmental simulation, Thermal shock testing, Package testing, Accelerated life testing
Scope and buying questions: Define the load profile, operating conditions, fixtures, instrumentation, and failure criteria. Which sequence best represents the intended use? Ask what monitoring, raw data, functional checks, and failure analysis are included alongside the final test report.
