4. QUALITY ASSURANCE PROVISIONS

4.1 Responsibility for inspection,. Unless otherwise specified in the

contract or purchase order, the contractor is responsible for the performance
of al 1 inspection requirements (examinations and tests) as specified herein.
Except as otherwise specified in the contract or purchase order, the
contractor may use his own or any other faci 1Ities sui table for the
performance of the inspection requirements specified herein, unless
disapproved by the Government. The Government reserves the right to perform
any of the inspections set forth in this specification where such inspections
are deemed necessary to ensure supplies and services conform to prescribed
requirements.

I 4.1.1 ~esponsibility for compliance. Unless otherwise specified, all

items shal 1 meet all requirements of sections 3 and 5. The inspections Set
forth in this specifi cation shal 1 became a part of the contractor’s overal 1
inspection system or quality program. The absence of any inspection
requirements in the specification shal 1 not relieve the contractor of the
responsibi 1ity of ensuring that al 1 products or supplies submitted to the
Government for acceptance comply with al 1 requirements of the contract.
Sampling inspection, as part of manufacturing operations, is an acceptable
practice to ascertain conformance to requirements; however, this does not
authorize submission of known defective material, either indicated or actual,
nor does it commit the Government to acceptance of defective material .

4.2 Classification of inspections. The inspection requirements

specified herein are classified as follows:

a. Qualification inspection (see 4.4)

~ . ..
I b. Quality conformance inspection (see 4.5)

4.3 Inspection conditions. Unless otherwise specified, all inspections

shal 1 be performed in accordance with the test conditions specified in
section 2, MI L-STD-202.

4.3.1 Light output criteria. Unless otherwise specified, 1ight output

criteria shall be as specified in the detail specification. The test
procedure for determining the change in 1ight output before and after burning
shal 1 be the same for any one type lamp.

4.3.2 Lamp operation. Unless otherwise specified, lamps shall be

operated at the rated voltage specified in the appl icable .detai1
specification. Voltage tolerance shal 1 be within ~ one-half percent of the
rated voltage (unless otherwise specified in the detail specification).

MI L-L-6363G

4.3.3 Lamp mounting. Unless otherwise specified, lamps shall be tested

in a lampholder or fixture suitable for the lamp under test. The lampholder
or fixture shall be rigidly mounted with no special provisions for absorbing
or isolating t~e effects of shock, vibration or temperature. When testing
directional beam lamps which require light distribution measurements to be
made relative to a specified reflector for flight axis,’ provision shall be
made in the test fixture for rotation of the mounted lamps to provide the
required measurement axis. Care shal 1 be taken to ensure that the 1ight
output measurements for each directional beam lamp is made on the same
mechanical angle each time so that changes in the beam axis can be detected.

4.3.4 Precautions. The following precautions shal 1 be observed when

performing the high temperature tests’:

a. The test chamber shall be capable of maintaining the specified

temperature within f50C (~1OoF). The test chamber shal 1 be
operated for 1 hour’ prior to installation of lamps to ensure that
the temperature has stabi 1ized.

b. Temperature measurements shal 1 be made with thermocouples having

leads at least 20 inches long within the oven. This will minimize
the conduction of heat away from the junction.

c. Baffles shall be placed within the oven so as to shield the lamps

and thermocouple junction: from direct radiation from the heating
elements and surfaces of the oven.

d. The lamps shal 1 be mounted so that there is a clear space between

the lamps equal to at least the width .of one lamp. The lamps shal1
be mounted so that the flux from any l-ampdoes not directly strike
any other lamp.

4.4 Qualification inspection. Qualification inspection shall be

performed at a laboratory acceptable to the Governrnent qualifying activity
(see 6.3), on sample lamps produced with equ~pment and procedures normally
used in production. The samples may “be selected at random from recent
production or fabricated, i! 1amps of recent production are not available.
Qualification Inspection shall be classified as follows:

a. Full qual if!cation - Lamp samples shall be subjected to and pass

all inspections and tests specified in table I.

b. Qualification by similarity - Lamp samples shall be subjected to

and pass all inspections and tests specified in table II.

4.4.1 Extension of qualification by similarity. Unless otherwise

specified, qualification of similar lamps from the same or different detail
specifications may be extended from a previous fully qualified lamp, provided
the fol lowing conditions are met and the requi red data and samples are
supplied to the qualifying activity.
