4.6 Methods of examination and test.
4.6.1 Visual and mechanical examination. Switches shall be examined to determine that the materials, design,
construction, physical dimensions, markings, and workmanship are in accordance with the applicable requirements
(see 3.1, 3.4, 3.5, 3.28, and 3.33), and when specified, switches shall be X-rayed in two planes perpendicular to its
axis to ascertain correct alignment of all internal actuating elements, the integrity of the unit, and any entrapped
foreign matter.
