Description
The Reference Block Type 2 is a standardised penetrant testing reference panel designed for the routine assessment and verification of Dye Penetrant Inspection (DPI) and Fluorescent Penetrant Inspection (FPI) system performance. Manufactured in accordance with ISO 3452-3, it provides a reliable method of monitoring penetrant sensitivity, washability and overall inspection process performance.
The reference block is manufactured from stainless steel, plated with nickel followed by a hard chromium alloy coating. Five artificial star-shaped defects, ranging from approximately 3.0 mm to 5.5 mm in diameter, are produced in the plated surface to assess penetrant detection sensitivity.
In addition to the artificial defects, the block incorporates four adjacent surface roughness patches with specified roughness values of Ra 2.5 µm, 5 µm, 10 µm and 15 µm. These areas allow assessment of excess penetrant removal and washability during the inspection process.

Important Information
Reference Block Type 2 is intended for routine assessment of penetrant testing system performance. It is not designed for determining penetrant sensitivity classification or for comparative testing between different penetrant systems.
For accurate and consistent results, testing should be carried out in accordance with the applicable inspection procedure and ISO 3452-3 requirements.
