SURFACE MEASUREMENTS
| NOMINAL GRIT | RA MEASUREMENT | TYPICAL APPLICATIONS AND TECHNIQUES | |
|---|---|---|---|
| Micron (micrometer) | Micro-inch | ||
| 80 | 2.5 | 100 | Dull polish – applicable for tube, bends and tees in general food processing subject to daily cleaning in place (CIP). Normal abrasive techniques achieve this. |
| 100 | 1.2 | 48 | |
| 120 | 1.0 | 40 | |
| 150 | 0.8 | 32 | Satin polish – used by high end food and beverage plants, cosmetics, toiletries and with standard pharmaceutical and biotechnology applications. Easier to CIP. Sequential use of abrasives is required. |
| 180 | 0.6 | 24 | |
| 240 | 0.5 | 20 | |
| 320 | 0.4 | 16 | Bright polish – Top end pharmaceutical (water for injection), high value biotechnology materials, semi-conductors, solvents and pure gases. Abrasives plus electropolishing normally required. |
| 500 | 0.1 - 0.2 | 4 - 8 | |
