What does LPI stand for?

Explanation:
LPI stands for Liquid Penetrant Inspection, a surface defect detection method in nondestructive testing. You apply a liquid penetrant to the surface, let it seep into any surface-breaking cracks, wipe away the excess, apply a developer to draw the penetrant out of flaws, and then inspect under appropriate lighting (visible or fluorescent). This method specifically uses liquid penetrants to reveal flaws at the surface, which is why this expansion is correct. The other terms aren’t standard NDT phrases: lateral penetration index, laser penetrant imaging, or liquid protrusion indicator aren’t recognized names for this technique.
