Other Criteria - std301320040045

DOE-STD-3013-2004

1) The purpose of the 9-meter drop test of the entire package is to ensure that a

storage package accidentally dropped from the maximum storage height would

not release any material. The number of tests, the number of samples per test,

and the drop orientation of the samples are specified in 49 CFR 178.603(a). The

target for the drop tests is defined in 49 CFR 178.603(d). The distance of the

drop is measured from the target to the lowest point on the sample container.

The drop height specified in the criterion is to be used instead of the heights

indicated in 49 CFR 178.603(e). The criterion for passing the test is that it retain

its function, (i.e., that it remain leak tight as defined by ANSI N14.5 [ANSI

1997]).

2) The purpose of the 1.3-meter drop test for the inner container is to ensure that a

loaded inner container accidentally dropped from the maximum packaging height

would not release any material. See A.6.2.3.1 for details of the tests.

3) The hydrostatic proof test provides verification that the container will remain leak

tight under maximum design conditions, plus a safety margin.

2. Testing During Use

ANSI N14.5, Leakage Tests on Packages for Shipment, specifies that the acceptable

maximum leak rate is 1 x 10-4 std. mm3/sec (1 x 10-7 std. cm3/sec) of dry air at one

atmosphere [ANSI 1997]. Full penetration weld closures provide the highest integrity

and longest life seals possible. Welds eliminate gaskets, which may degrade and

leak. Mechanical seals using bolts or screwed connections are susceptible to wear,

creep relaxation, seizure, or other mechanical failure.

Other Criteria

1. Identification markings are required on all storage containers to facilitate

maintenance of an inventory data base and management of stored materials.

2. The outer container will be placed in and moved through contamination-free areas. It

is important that the container not compromise the contamination-free nature of

those areas. Further, the outer container, when open prior to filling or loading,

should still be capable of placement in, or transport through contamination-free

areas.
