4. QUALITY ASSURANCE PROVISIONS
4.1 The supplier is responsible for the performance of all inspec-
tion requirements as specified herein. Except as otherwise specified,
the supplier may utilize his own or any other inspection facilities
acceptable to the Government. Inspection records of the examination
and tests shall be kept complete and available to the Government as
specified in the contract or order. The Government reserves the
right to perform any of the inspections set forth in the specification
where such inspections are deemed necessary to assure supplies and
services conform to prescribed requirements.
4.1.1 Sampling. Unless otherwise specified, and when applicable,
the sampling plans and procedures used by the Government inspector in
the determination of the acceptability of products submitted by a
supplier for Government inspection, shall be in accordance with the
provisions set forth in MIL-STD-105.
4.1.2 Preproduction sample. Unless otherwise specified for each
contract or order, a representative sample of five arming devices
shall be manufactured using the methods and procedures proposed for
the production lot. These shall be submitted to the Government inspector
for preproduction tests at an activity designated in the contract or by
the Bureau of Naval Weapons for purposes of determining compliance with
the requirements of the contract, specifications, and drawings. Further
production of the arming device by the contractor prior to approval of
the contracting activity or the completion of tests on the preproduction
samples shall be at the contractor's risk. Preproduction samples
accepted will be applied as part of the quantity specified by the
contract or order.
4.1.3 Lot size. As applied to Government inspection of units of
product, the term "lot" shall mean "inspection lot," i.e., a collection
of units of product submitted by a supplier for Government inspection.
Unless otherwise specified, the number of units of product in
"inspection lots" will be as determined by the Government inspector and
may differ from the quantity designated in the contract or order as a
lot for production, shipment, or other purpose.
4.1.4 Periodic production samples. From each succeeding lot or
grand lot of 300 or less, a random sample of 5 arming devices will be
selected by the Government inspector for submission to a Bureau of Naval
Weapons assigned activity to determine compliance with the requirements
of the contract, specifications, and drawings.
