PSM-5 Test Panel
The PSM-5 panel is used for verification of operation (performance) of the system (ČSN EN ISO 3452-1) at the beginning of each working period.
This panel is composed from 2 parts:
- defect surface
- rinsing surface
The defect surface contains 5 imprints with graduating scales.
The rinsing surface enables verification of washing away ability of penetration agents.
The panel is supplied with either one of 2 types of rinsing surface:
- smooth, chromed
- rough, sanded
The approximate sizes of the imprints on the defect surface (varying panel from panel) are the following:
| E | D | C | B | A | |
| IN | 0.210 | 0.148 | 0.086 | 0.062 | 0.031 |
| mm | 5.34 | 3.75 | 2.19 | 1.57 | 0.79 |
The basic dimensions valid for both types are:
0.09 x 4 x 6 IN (2.286 x 101.6 x 152.4 mm)
This panel meets the requirements of the norms MIL – STD – 6866 and ASTM E – 1417
Note: This panel must never be used as an equivalent panel for cases where there is required the gauge N.2 according the the norm ČSN EN 3452-1.
Below is the comparative chart of the imprints between PSM-5 and a Type 2 gauge according EN 3452-3
| Gauge Type | PSM-5 | Type 2 according to EN 3452-3 |
|---|---|---|
| Number of Imprint | typical size (average) of imprint in mm | |
| 1 | 0.79 | 3.0 |
| 2 | 1.57 | 3.5 |
| 3 | 2.19 | 4.0 |
| 4 | 3.75 | 4.5 |
| 5 | 5.34 | 5.5 |
