When specified (see 6.2), a sample shall be subjected to first article inspection(see 6.3) in accordance with 4.4.3.2 Formulation. The PBXN-111 shall be a plastic-bond
17、ed, castable material that contains aplastic material used to bond the solid component material to form a flexible explosive. Theformulation of explosive PBXN-111 shall comply with the requirements specified in table I (see 6.7).3.2.1 Cure conditions. The explosive shall be cured at a temperature be
18、tween 20 and 50C until aShore A hardness of at least 20 is measured.3.2.2 Equivalent ratio. The weight percent of the polybutadiene and the isodecyl pelargonate shallbe kept in a ratio of 1:1 0.05. The weight percent of the polybutadiene and the isocyanate shall becalculated using an NCO/OH ratio of
19、 1:1 0.05. The NCO/OH ratio shall be calculated using theequivalent weights of materials obtained by chemical analysis using the techniques of 4.5.2 of WS 16305 and 4.6.2 of WS 23148. To avoid shelf life problems with component materials, thischemical analysis must be conducted at least every six mo
20、nths on lots of materials being used. Theweight percent of each ingredient shall be determined to two significant figures (see 6.4).3.2.3 Uncured explosive requirements. The uncured explosive shall have a maximum moisturecontent of 0.05 percent, as determined on a sample of uncured explosive taken b
