Family-level profile
AP5000-series HEPA Test PSL particles
| Attribute | Current Applied Physics page |
|---|---|
| Intended use | HEPA/ULPA filter efficiency, leak testing, aerosol generation and research |
| Published range | Approximately 30 nm–3.1 µm |
| Published concentration | 10% solids by weight |
| Published volumes | 15 mL, 100 mL and 1,000 mL pathways |
| Explicit limitation | Not intended for instrument calibration or diagnostic reagents |
Why the limitation matters
Challenge-grade and calibration-grade are different
The AP product page explicitly separates this family from instrument-calibration material. A challenge family can prioritize aerosol generation, concentration and test economics while a calibration standard must satisfy a different evidence and uncertainty need.
Do not relabel the product in downstream content. Preserve the manufacturer’s intended-use limitation on product pages, proposals and procedures.
