GOVERNMENT QUALITY ASSURANCE ACTIONS

The quality programs of the

contractor

and of

his

subcontractors are subject

to

continuous evaluation,

review,

and inspection by the cognizant NASA installation

or

its

designated representat ives. Actions by or on behalf of the Government

will determine not only

whether

the requirements ofthis publ ica tion have been

met,

but

5.5

ONTR TOR SOUR E INSPE TION

The contractor shal l either provide for

non-Govermnent inspection at

source

or

require

objec ti ve evidence that the subcontractor complies in detail

with

applicable requirements

when the procuring contractor s receiVing inspec

cannot verify the

quality

of the ar t ic les

because

of the following:

a.

Artic les

being

procured

are

at a

level

of assembly which prevents

verificat ion of quality at the procuring contractor s plant,

or

b.

In-process

controls have such an effect on the

quality

of the

art icles , that

the

qua li ty canno t be

determined

solely by inspec

t ion

or tes ts

of

the

completed

c .

Verification tests are destrucbve in
