Testing: Scope, Evidence & Reports

DOES buyer reference | Updated November 12, 2026

A useful test starts with a clear question and ends with evidence that answers it. Before sending detail parts, components or subassemblies, agree what will be tested, who will perform the work and how the result will be accepted.

1. Define the item and decision

Identify the item type, quantity, material and configuration at a non-sensitive level. Clarify whether the purpose is development learning, defect screening, production acceptance or an investigation. These purposes can require different methods and records. Use an agreed channel for drawings, proprietary information and controlled technical data.

2. Agree the technical scope

The authorized technical owner should identify the applicable specification and revision, method or procedure, coverage, test conditions and acceptance criteria. Identify any required hold points and who may approve changes. A commercial inquiry is not a substitute for an approved procedure or engineering disposition.

3. Verify provider and personnel fit

Confirm the performing organization, work location, method capability, relevant personnel qualifications, equipment suitability and calibration evidence. Review any customer-required certification or accreditation for its actual scope and validity. A general quality-system certificate does not by itself qualify every test method.

4. Define the report before work starts

Agree the identifiers needed to connect the report to the tested item: part or assembly identification, revision where applicable, serial or lot reference, test date, procedure/specification revision, method, coverage and conditions. Agree whether readings, observations, images, equipment references, limitations and reviewer authorization must accompany the result.

5. Separate results from disposition

A report should state what was observed or measured and compare it with the agreed criteria where the scope requires that comparison. Missing coverage, deviations and limitations should be explicit. Repair approval, design acceptance and release to service remain with the authorized party unless specifically included in the agreement.

6. Agree logistics and records

Confirm handling, packaging, contamination restrictions, shipment authorization, data rights, report access and record-retention responsibilities. Agree scope, quotation and schedule before shipping. Do not send customer parts or sensitive files without coordination.

A simple pre-award checklist

Can the buyer and provider each identify the same item, method, criteria, qualified performer, evidence package, approver and delivery expectation? Resolve differences before work begins. This is a general scoping aid; the controlling contract, specifications and authorized technical decisions govern.

How DOES supports the work

DOES scopes and coordinates NDT, NDE and general testing through qualified subcontractors for aviation, aerospace and defense, space, nuclear and microelectronics applications. The provider, methods, personnel qualifications, applicable specifications, criteria and reporting are agreed for the engagement.
