Sampling for tests.
Hazard Notice
The materials described herein are flammable or explosive or
both. Consequently, they present hazards in manufacture,
handling, storage and shipment. The contractor should
recognize these hazards and take appropriate measures to
guard and protect against fire, explosion, adverse
environment, corrosive atmosphere, rough handling and
electrically-induced incidents.
4.5.3.1 Sampling of Composition A-5. The tests in 4.6
shall be performed on samples representative of the batch
which were taken in accordance with ASTM E300, for solids.
Approximately 1 kg sample shall be obtained from each batch
produced.
4.5.3.1.1 Sampling of Composition A-5, Class 1. The
selection of batches for testing for Composition A-5, Class
1 shall be in accordance with MIL-STD-1916 except that in
lieu of Table IV (MIL-STD-1916), the following continuous
sampling plan shall be used: i=7, f=1/3 and there shall be
no reduced or tightened inspection level. If any sample
fails to meet any test requirement, the batch represented by
the sample shall be rejected. All batches produced between
the time that the last batch was tested and accepted and the
batch which failed shall be tested in accordance with the
applicable methods given in paragraph 4.6, unless otherwise
directed by the contracting officer. If any of these
batches fail to meet any of the test requirements, that
batch shall also be rejected. In addition, after any
failure of a batch the contractor will return to 100%
inspection until "i" successive batches are accepted in
accordance with MIL-STD-1916.
4.5.3.1.2 Sampling of Composition A-5, Class 2. Testing
for Composition A-5, Class 2 shall be conducted on 100% of
the batches. If the sample for a batch fails to meet any of
the test requirements, the batch shall be rejected.
4.5.3.2 Sampling for density/sensitivity test. A
representative sample of approximately 200 grams Composition
A-5 shall be taken from the sample obtained in accordance
with 4.5.3.1. The inspection samples for Class 2
Composition A-5 shall be 100%. If any sample fails to meet
the test requirements of 4.6.7 the batch represented by the
sample shall be rejected as Class 2 material.
