Dye penetrant inspection: Dye penetrant inspection (DPI)‚ also called liquid penetrant inspection (LPI)‚ is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals‚ plastics‚ or ceramics). Penetrant may be applied to all non-ferrous materials‚ but for inspection of ferrous components magnetic-particle inspection is preferred for its subsurface detection capability. LPI is used to detect casting and forging defects‚ cracks‚ and

Hypothesis testing begins with the assumption that randomization is used to collect quantitative data about the sample and that the distribution of this data has a normal shape. Significance tests state two explanations‚ or hypotheses‚ about a parameter. One‚ called the null hypothesis‚ states that the parameter equals some value (usually 0). The other‚ called the alternative hypothesis‚ states that the parameter is greater than‚ less than or (not) equal to the value stated in the null hypothesis
