inspections shall be taken in accordance with ASTM D 4057 and ASTM D 4177.
4.3.2 Sampling for examination of filled containers. A random sample
of filled containers shall be drawn from each lot in accordance with ANSI Z1.4
to verify compliance with this specification regarding fill, closure, marking,
and other requirements not involving tests.
4.3.3 Examination of filled containers. Samples shall be examined for
defects of the container and the closure, for evidence of leakage, and for
unsatisfactory markings; each sample-filled container shall also be weighed to
determine the amount of the contents.
4.4 Test methods. Testing shall be in accordance with applicable test
methods given in tables I and II and in 4.4.1 through 4.4.8.
4.4.1 Preparation of specimens for protection tests. Three specimen
panels shall be prepared for each protection test.
.
4.4.1.1 Panel composition and size. Steel panels shall be fabricated
from open hearth, cold finished, dead soft temper, low carbon steel conforming
to ASTM A 1008/1008M. The panels shall be 5.08 by 10.16 by 0.32 cm (2 by 4 by
1/8 inch) conforming to those panels specified in ASTM D 1748.
