Final answer:

The ASTM F1929-12 covers three dye-application methods: dip immersion, edge dip, and eye dropper. A dye penetrant is a colored dye used in detecting leaks in packaging. The method has limitations such as the need for accurate application and it's ineffective for detecting microscopic leaks.

Explanation:

The ASTM F1929-12 covers three dye application methods for the detection of gross leaks in packaging. The three methods involved are: (1) dip immersion, (2) edge dip, and (3) eye dropper.

The term dye penetrant refers to a colored dye - often red - that is used to test for leaks in the packaging by soaking into flaws and cracks, thus making them visible.

Despite its wide usage, the dye penetrant method has its own limitations. First, it requires mastery and correct application of the procedure in order to gain reliable results. Second, it's not effective in detecting microscopic leaks or pores that are too tiny for the dye to penetrate.
