| the contract or purchase order, the contractor may use his own or any other facilities
suitable 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 the specification where such inspections are deemed necessary to
ensure supplies and services conform to prescribed requirements.
4.1.1 Responsibility for compliance. All items shall meet all require-ments of sections
3 and 5.
The inspection set forth in this specification shall become a part of the
contractor's overall inspection 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 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 accept defective material.
4.2 Classification of inspections.
The inspection requirements specified herein are
classified as follows:
a.
Qualification inspection (see 4.4)
b.
Quality conformance inspection (see 4.5).
4.3
Sampling.
4.3.1 Qualification sample. The qualification sample shall consist of 3 gallons of each
component. The material shall be packaged in suitable containers and forwarded to the
Commanding Officer, Naval Weapons Station, Yorktown, Va. 23491, Attn: NEDE Department. Each
sample submitted shall be plainly identified by securely attached durable labels marked with
the following information:
a. Compound, Polymeric Elastomer, Thermosetting
b. Components A and B
c. Name and address of manufacturer
d. Location and identity of the plant which produced the samples
e. Manufacturer's identification
f. Date of manufacture
g. Submitted by (name), (date), for qualification tests in accordance with the
requirements of MIL-C-82633.
4.3.2 Quality conformance samples. The quality conformance samples shall consist of
a sample for tests and a sample for examination of filled containers. The sample for test
shall be labeled with complete information on each component designation, on the lot and
batch number, date of sampling, contract number, and applicable specification.
4.3.2.1 Inspection lot. An inspection lot shall consist of the same type polymeric
compound produced by one manufacturer, at one plant, from the same materials, and under
essentially the same manufacturing conditions.
4.3.2.2 Sample for tests. A 2-gallon sample of each component shall be taken at random
from each lot in accordance with method 101.11 of SS-R-406 and subjected to tests of 4.6.
Unless otherwise specified, the values specified in section 3 apply to the average of the
results obtained from duplicate determinations for each particular test. The lot shall be
unacceptable if a sample fails to meet all the requirements of this specification except
as noted in 4.5.
4.3.2.3
Sample for examination of filled containers.
A random sample of filled
containers shall be selected from each lot of compound in accordance with MIL-STD-105 at
inspection level I and with an acceptable quality level (AQL) of 2.5 percent defective and
examined for fill, closure and damaged or leaking container, improper container, and
marking. The sample containers shall be shipped as part of the lot if the lot is accepted.
4.3.2.4 Conformance of the compound to the requirement for workmanship and any other
requirements not covered by specific tests shall be determined by appropriate visual
examination.
4.4 Qualification inspection. The qualification inspection shall consist of all the
tests of this specification as described in 4.6. The qualification sample shall be examined
and tested for all the requirements of this specification. The cognizant agency (see 6.3.1)
reserves the right to accept the manufacturer's certification of testing, when available,
in lieu of Government testing.
