Start with scope
Explain quality methods, standards scope, test requirements, version control, market applicability and evidence verification.
How we structure the research
- Identify the exact product, process, market and version
- Locate the applicable requirement in an official source
- Check evidence scope, issuer, method and date
- Record exclusions and avoid claiming certification from a logo
Choose suitable sources
Use official documentation, original research and relevant technical references. State versions, dates, units and important conditions alongside the claim. Manufacturer documentation can establish what that manufacturer specifies; broader claims may require independent evidence.
Distinguish evidence and illustration
Diagrams on the site may simplify a concept. They are illustrative, not test records, engineering drawings or certification evidence. Examples are not customer case studies unless clearly substantiated.
Keep uncertainty visible
Show assumptions and exceptions. Link to the source that supports a claim, and state when evidence is incomplete or conflicting.
