4.3.1 First article samples. Unless otherwise specified, as soon as practicable after the
award of the contract or order, the manufacturer shall submit two complete converters, one inner
vessel (complete with all lines and fittings) and one secondary overpressure safety device. The
samples shall be representative of the construction, workmanship, components, and materials to
be used during production. When a manufacturer is in continuous production of these units from
contract to contract, submission of further first article samples on the new contract may be
waived at the discretion of the procuring activity (see 6.2b). Approval of the first article samples
or the waiving of the first article inspection does not preclude the requirements of submitting to a
conformance inspection. The first article inspection samples shall be furnished to the
Government as directed by the contracting officer (6.2c).
4.3.1.1 First article information. Upon completion of the first article inspection program,
pertinent comments and recommendations will be forwarded by the Government activity
responsible for conducting the inspection program (see 6.2c) to the contracting officer. One
approved converter shall be returned to the manufacturer for use in monitoring production. The
other sample shall be consumed or destroyed in the first article inspection and shall not be
considered as part of the quantity to be delivered under the contract.
4.4 Conformance inspection. The sampling and inspection levels shall conform to
ASQ-Z1.4. Conformance inspection shall consist of the following examinations and tests:
Visual examination
Dimensions
Permanent volumetric expansion
Pressure tests
Filling time
Buildup time
Dielectric strength
Insulation resistance
Relief valve test
Sensing element calibration
Evaporation loss tests
Secondary overpressure safety
