Clear assignment
Documents are clearly assigned to the order, line item, or lot.
Quality documentation
Quality assurance and documentation in manufacturing
During ordering and production there are many inspections and documentation steps to ensure quality standards and transparency. Because this documentation landscape can become confusing quickly, we give you an overview of the documents we can provide - some mandatory, some available on request.
What are the core principles of quality documentation?
To guarantee the quality of manufactured parts, requirements are verified through suitable inspection methods and clear documentation. Documentation accompanies the full production process and includes information from drawings, specifications, purchase orders, and industry or mandatory standards such as ISO certifications and ISO norms.
Transparent inspection scope
It remains transparent which characteristics were checked and to what extent.
Evidence and traceability
Measurement results, material evidence, and conformity confirmations stay documented in a structured way.
Document control
Creation, review, release, and archiving follow controlled and traceable rules - partly automated through our digital manufacturing platform.
Overview of document types
The overview below helps classify the main document types. Details on individual documents are covered in the next sections.
EN 10204
What are EN 10204 material certificates?
Material certificates according to EN 10204 mainly differ in two ways.
→
Whether the inspections are non-specific, meaning they describe typical values, or specific to the actual delivery or batch.
→
Who confirms the document - internally by the manufacturer or additionally with independent acceptance.

Inspection reports and measurement protocols
Dimensional inspection report and measurement protocol
- Feature list, target-vs-actual values, tolerances, and result
- Inspection scope, measuring equipment, date, and assignment to lot or part number
- Particularly useful for critical fit surfaces, sealing areas, functional dimensions, tight tolerances, and first parts
Functional / final inspection report
- Inspection steps and acceptance criteria
- Measured value or status for each step plus serial number or lot
- Useful for leak testing, torque, force, flow, pressure, or electrical inspections
Special inspections
What inspections are included in first articles and first samples?
When a part is new, receives a revision, or moves into serial ramp-up, a normal final inspection is often not enough. In such cases, a first article inspection is performed. First articles are parts manufactured for the first time under realistic serial conditions.
This does not only refer to the part itself, but to a representative production run that reflects the future serial state. First article submission therefore usually includes both the product and the production process.
What exactly is a first article?
A first article comes from an initial production batch under serial conditions. For the submission process, a quantity agreed in advance with the customer is released from that batch.
A representative serial run means production takes place at the final manufacturing location, runs over a realistic time interval, covers a defined customer quantity, and is completed entirely under serial conditions.
- Materials, tools, manufacturing equipment, and inspection equipment match the serial setup
Checklist: what is needed for successful document control and delivery?
assemblean manages smooth document control and delivery, both digitally and in paper form. To create the requested documentation successfully and keep traceability intact, the following information should be clarified during project setup:
✓
Drawing number and revision
✓
Specification and standards
✓
Required document scope
✓
Inspection scope: sampling or 100%
✓
Language and format
✓
Traceability requirements (supply chain law)
