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).
Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and is used widely in a variety of industries.
The British standard defines the liquid limit as the water content of a soil at which a 80g, 30º cone penetrates 20mm. Because it is difficult to obtain a test with exactly 20 mm penetration, the procedure is performed multiple times for a range of water contents and the results are interpolated.
The six most frequently used NDT methods are eddy-current, magnetic-particle, liquid penetrant, radiographic, ultrasonic, and visual testing. [3] NDT is commonly used in forensic engineering , mechanical engineering , petroleum engineering , electrical engineering , civil engineering , systems engineering , aeronautical engineering , medicine ...
The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils.
The California Bureau of Cannabis Control implemented Phase 3 testing standards on Jan. 1, 2019, which included analytical testing for heavy metals. How to Tell if Your Vape Cartridge is Legit or ...
Dye-n-Pry is a useful technique in which a dye penetrant material is used to inspect for interconnect failures in integrated circuits (ICs). This is mostly commonly done on solder joints for ball grid array (BGA) components, although in some cases it can be done with other components or samples. The component of interest is submerged in a dye ...
