A Penetration Testing Block is a standardized reference tool used to assess the effectiveness of liquid penetrant testing (PT) techniques. These blocks are designed with specific defect patterns, such as cracks, grooves, or notches, to simulate real-world material flaws. By applying penetrant chemicals to the block and observing the results, inspectors can verify that their testing process is effective and sensitive enough to detect flaws in actual components.
