Policy
How technical content is created
- Use primary sources such as standards bodies, NIST and current manufacturer documentation where available.
- Distinguish current product specifications from legacy content and general technical guidance.
- State assumptions, limitations and application boundaries.
- Avoid claims of regulatory approval, endorsement or universal compliance without evidence.
- Use lot-specific certificate values instead of generic marketing values for measurement decisions.
- Correct material errors and update pages when controlling sources change.
Source hierarchy
What controls when sources conflict
| Priority | Source |
|---|---|
| 1 | Current lot-specific certificate, quotation and product documentation |
| 2 | Current Applied Physics product page and controlled technical document |
| 3 | Official standards body, NIST or regulator source |
| 4 | Current technical publication or peer-reviewed research |
| 5 | Legacy Applied Physics page or archived reseller material, clearly labeled |
| 6 | General educational inference, explicitly identified |
