supersedes applicable laws and regulations unless a specific exemption has been obtained.
3. REQUIREMENTS
3.1 First article inspection. Unless otherwise specified in the contract or purchase order (see 6.2), a
first article sample of the explosive material shall be manufactured using the same formulation, process,
and procedures proposed for the production of the material. This sample shall be tested as specified in 4.4
prior to production, to determine that the contractor prior to starting production, is capable of producing
the explosive material in conformance with the requirements of this specification.
3.2 Materials. The PBXN-109 explosive shall be a plastic-bonded and castable explosive material
and shall contain a plastic material which is used to polymerize with the other ingredients to make it more
flexible.
3.3 Formulation (M101). The formulation of explosive PBXN-109 shall comply with the
requirements specified in Table I.
3.3.1 Equivalent ratio. The weight percent of isophorone diisocyanate shall be calculated (see 6.6
for calculation) using an NCO/OH ratio between 1.0/1 to 1.1/1. The NCO/OH ratios will be calculated
using the equivalent weights of materials obtained by chemical analysis using the techniques of WS 23149
paragraph 4.5 (Quality conformance inspection), WS 16305 paragraph 4.5.2 (Isocyanate content), and WS
23148 paragraph 4.6.2 (Hydroxyl content determination). To avoid shelf-life problems with component
