It is used as a quality control and inspection test to reveal by deep acid etching the macrostructure in specimens cut from bars and to show the presence of such conditions as pipe, cracks, porosity, segregation, or foreign material. The etched surface is generally examined visually, but magnification up to about 10<span class=\"unicode\">\u00d7<\/span> is occasionally employed.<\/p>\n<p id=\"s00051\">1.2 The values stated in inch-pound units are to be regarded as standard.
