(b) Quality conformance inspection (paragraph 4.4)
(c) Periodic production inspection (paragraph 4.5)
4.3.1 Preproduction. A preproduction sample of five beacon lights,
manufactured in accordance. with 3.2.2, shall be subjected to the pre-
production tests detailed in 4.5 at an activity designated by the
procuring activity. Acceptance of the preproduction sample shall be
based on no defects in the sample. Further production of the beacon
light by the supplier, prior to the approval of the preproduction
sample, shall be at the supplier's risk.
4.3.2 Lot size. Unless otherwise specified in the contract or
order, each shipment of units of product shall be a separate `*inspec-
tion lot" and may differ from the quantity specified in the total
order or contract. In any event, all units of a single "inspection
lot" shall be made to the same design, with the same materials and
manufacturing techniques, and shall be part of one continuous pro-
4.3.3 Periodic production samples. From each succeeding lot or
grand lot of 300 or less that have passed the quality conformance
inspection of 4.4, a random sample of five beacon lights will be
selected for submission to an activity designated by the procuring
activity to determine compliance of the samples with the require-
ments of the contract, specification, and drawings. The beacon
lights shall be considered satisfactory if they meet all specifica-
tions and pertinent drawings requirements and withstand the tests
specified in 4.4 and 4.5. Failure of the periodic production sample
to comply with these requirements will result in the rejection of
the lot, as determined by the procuring activity.
4.4 Quality conformance inspection. Each beacon light delivered
under contract shall be subjected to the following tests and exam-
inations. Failure to meet any requirement specified herein shall
be considered cause for rejection.

beacon light shall be subjected to quality conformance tests under
the following conditions.
