Have you implemented surface classification per Part 9? Let’s discuss below. 👇 Title: ISO 14644-9 PDF – Quick Guide to Surface Cleanliness Classification
| System | Contaminant | Typical Units | Common Method | |--------|-------------|---------------|----------------| | System A | Non-viable particles (≥0.05 µm) | Particles/m² | Surface particle counter, microscopic | | System B | Viable particles (CFU) | CFU/m² or CFU/contact plate | Contact plate, swab, air sampler (surface mode) | Iso 14644-9 Pdf
This standard defines classification systems for surface contamination by solid particles – both non-viable (dust, fibers) and viable (microbes). Use it to set limits for product-contact surfaces, walls, floors, or equipment in cleanrooms. Have you implemented surface classification per Part 9
Looking to classify surface contamination by chemical or molecular layers? That’s where ISO 14644-9 comes in. Use it to set limits for product-contact surfaces,
While most cleanroom professionals know Part 1 (airborne particles), Part 9 focuses on – specifically classifying surface cleanliness by particle concentration (non-viable & viable).
