“无损检测 渗透检测用试块（英文版）”介绍

Penetrant inspection test blocks are crucial elements within the non-destructive testing (NDT) industry, especially for evaluating surface defects on materials or components without causing any harm to them. These specialized blocks simulate various types of surface flaws in different sizes and shapes, enabling users to verify the effectiveness of their penetrant inspection procedures, as well as the sensitivity of the penetrant systems used.

Made from materials like metal, plastic, or glass, these test blocks are precision-engineered with specific types of cracks, such as fine lines, star-shaped cracks, holes, or even more complex geometrical patterns. They are utilized to confirm that the entire penetrant inspection process—which includes pre-cleaning, application of penetrant, removal of excess penetrant, developer application, and flaw revelation—is conducted correctly and effectively. Furthermore, they play a vital role in the certification and training of personnel involved in this kind of NDT, ensuring high standards and reliability in defect detection across industries like aerospace, automotive, and manufacturing.
