NDT PT Type II Reference Test Block 2.5-15μm Roughness Patches for Penetrant System Calibration ISO 3452-3: 2013 describes two types of reference blocks - Type 2 reference blocks are for routine assessment of DPI system performance. Reference block type 2 is made from stainless steel plated with a layer of nickel then a hard Chromium alloy. Five star-shaped defects of ranging from 3.0 to 5.5mm diameters have then been artificially produced in this layer with the five defects
