Refer to the design and dimensions of test block Type 2
1 Design
1.1 General Provisions
The inspection panel (see Figure 2) is rectangular in shape and measures 155mm x 50mm x 2.5mm.
Note: All dimensional deviations are ± 10%, unless otherwise stated.
The base material is stainless steel X2Cr NiMo17-12.3(1.4432) in accordance with EN10088-1, with an initial hardness of HV20=150 ± 10 or equivalent
1.2 Washable area
To examine the washability of the penetrant, four adjacent areas with dimensions of 25mm and 35mm were fabricated on one of the detection surfaces of the panel, with roughness of Ra=2.5μm, Ra=5μm, Ra=10μm and Ra=15μm respectively (see Figure 2).
The area with Ra=2.5μm can be obtained by grinding with a grinding wheel, while the rest can be achieved through electroplating.
1.3 Defect Area
The defect area is on the other half of the panel inspection surface (see Figure 2).
1.3.1 Electroplating
The inspection surface of the panel should be plated with a non-electroplated nickel layer of 60μm ± 3μm thickness to achieve a hardness value range of HV0.2=500-600.
This nickel layer should be plated together with a chromium layer with a thickness of 0.5μm to 1.5μm. Then the panel should be heat-treated to achieve a hardness range HV0.3=900-1000, for instance, by heating to 405℃ and holding for 70 minutes. The roughness Ra of the chromium layer should be 1.2μm to 1.6μm.
1.3.2 Artificial defects
On the other side of the inspection surface (the coating area), five equidistant notches should be made using a typical load range of 2KN to 8KN.
For example, five artificial defects can be manufactured using the loads given in Table 1:

The artificial defect notches are fabricated using compressors (120KN) or appropriate vickers with hemispherical cone heads.
