Methodology for Long-Term Permeation Test Periods for HD in High-Density Polyethylene: Universal Munitions Storage Container for the Non-Stockpile Chemical Materiel Program
Abstract
As part of the Explosive Destruction System for the Non-Stockpile Chemical Materiel Program, the Universal Munitions Storage Container was evaluated as a storage candidate for over-packing leaking and non-leaking munitions that contain chemical warfare agents. A 12 year storage period was the program target. Permeation experiments were performed with a series of material thicknesses over a 13 month period, and thickness versus breakthrough time was extrapolated to the 12 year target. Permeation breakthrough measurements for distilled mustard (HD) and non-welded high-density polyethylene (HDPE) at 120 F were completed for thicknesses of 2080 mil for extrapolation to the ~250 mil container thickness. A Ficks law extrapolation inferred a breakthrough time of 1011 days for the 250 mil non-welded HDPE at 120 F. It is unlikely that a 250 mil thick HDPE container will provide safe containment for the target 1 year period. A custom methodology was developed for the long permeation periods. Expected breakthrough times and, therefore, test times were unknown; thus various permeation times were included in the experimental plan. The methodology developed was successful in providing the necessary measurements. This long-term methodology provides a new capability in permeation cup testing
