Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
Test materials can be damaged if compatibility is not ensured. The operator or their supervisor should verify compatibility on the tested material, especially when considering the testing of plastic components and ceramics. The method is unsuitable for testing porous ceramics. Penetrant stains clothes and skin and must be treated with care
Materials testing is used to assess product quality, functionality, safety, reliability and toxicity of both materials and electronic devices.Some applications of materials testing include defect detection, failure analysis, material development, basic materials science research, and the verification of material properties for application trials.

Active thermography is an advanced nondestructive testing procedure, which uses a thermographic measurement of a tested material thermal response after its external excitation. This principle can be used also for non-contact [1] infrared non-destructive testing (IRNDT) of materials. [2]

Albert Henry Lightburn (c. 1877 – 27 October 1940) was a son of Liverpool marine engineer John Bolton Lightburn (c. 1840 – 5 May 1916) and his wife Matilda Lightburn (13 May 1847 – 10 May 1930) who arrived in South Australia from England in 1898 and lived in Athelstone until after John's death, when she lived with Albert in Unley.
