Chalk test
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
The forerunner of modern penetrant methods. a method of locating cracks by applying oil to a part and then removing the excess from the surface, which is then coated with whiting or chalk. after a short period of time the oil seeps out of the cracks into the whiting, or chalk, causing an appreciable difference in whiteness. this method has been replaced with more advanced penetrant methods for most applications.
