4.4 Conformance inspection.
4.4.1 Inspection lot. An inspection lot, as far as practicable, shall consist of all the switches of the same type
produced under essentially the same conditions and offered for inspection at one time. Switches meeting these
requirements but having different circuit configurations or varying number of switch decks, may be combined to form
a lot.
4.4.2 Sampling and inspection. Quality conformance inspection shall consist of the examinations and tests specified
in table II. The visual examination and dielectric withstanding voltage test shall be made on all sample units. The
remaining examinations and tests will be performed on the same sample units in the order shown.
