of the requirements set forth in this specification. The manufacturer
may be permitted to make modifications on the sample during the testing
phase where such modifications, in the judgement of the General Services
Administration and the testing facility, are clearly in the interest of
the Govern­ment.

\(c\) In case of failure of the sample, consideration will be given to
the request of the manufacturer for resubmission for retest only after
it has been clearly shown that changes have been made in the product
which the Government considers sufficient to warrant retest.

\(d\) The manufacturer or his representative will not be permitted to
observe the actual tamper resistance tests conducted on his product at
the testing facility. However, when samples tested fail to comply with
the requirements of this specifica­tion, the sample may be examined by
the manufacturer or his representatives and full details of the failure
may be made known to them in a manner which, for reasons of security,
will be in the best interest of the Government.

4.2.3.1 [Test samples]{.underline}. Ten qualification test samples shall
be forwarded at a time and to a place designated by the General Services
Administration. In the event the samples are destroyed or damaged to
such an extent during testing that testing cannot be completed, the
Government reserves the right to require the manufacturer to furnish
additional samples to complete the testing. Samples delivered to the
test facility shall have a tag attached, which shall reference this
specification and identify the sample by class, type, and strike.\
\
4.2.3.2 [Drawings and material specifications]{.underline}. The

No changes shall be made in the construction or construction drawings of
the pedestrian door deadbolts after it has become qualified and is
furnished under contract or order unless prior written authorization to
make changes is obtained from the GSA contracting officer.

4.3 Number range level3[Qualification testing]{.underline}.
Qualification testing shall consist of the following tests described
under test methods in 4.7. Failure of the sample to withstand one or
more of these tests shall provide reason to consider the product as
having failed to meet qualification requirements.

4.4 [Classification of inspections]{.underline}. The Quality conformance
inspection shall be classified as specified in 4.5.\
\
4.5 [Quality conformance inspection]{.underline}. The pedestrian door
deadbolts shall be examined for defects in accordance with Table II.
Presence of any defect listed shall provide reason to reject the
product. Rejected lock extensions may be reworked to correct defects and
they may be submitted for acceptance. Reworked lock extensions shall be
so indicated to the Government inspector.\
\
4.5.1 [Component and material inspection]{.underline}. The supplier is

system or quality program. The absence of any inspection requirements in
the specification shall not relieve the contractor of the responsibility
of ensuring that all products or supplies submitted to the Government
for acceptance comply with all requirements of the specification.
Sampling in quality conformance does not authorize the submission of
known defective material, either indicated or actual, nor does it commit
the Government to acceptance of defective material. The inspection level
shall be level II with an Acceptable Quality Level of 2.5 percent
defective.\
\
4.5.3 [Quality conformance testing]{.underline}. Periodically, during
the term of the contract, the Government inspector, at a time convenient
to the Government, may select samples of the manufacturer's regular
production to subject them to the tests in 4.7. This acceptance testing
shall be performed by a Government agency specifically designated by the
contracting officer. Failure of the lock to meet any one or more of
these tests shall provide reason to suspend acceptance of the
manufacturer's product until the Government is satisfied that all
defects have been corrected.
