Weights shall be measured with equipment having a minimum accuracy of 1.0 percent of the nominal ingredient weight sp
30、ecified in Table I. 3.3.2 Ammonium perchlorate (AP) ratio of particle sizes. Control of the propellant burn rate shall be maintained by varying the ratio of weight fractions of the unground (coarse) and ground (fine) ammonium perchlorate (see Table I). The weight fractions are the weight of the coar
31、se AP or fine AP divided by the total weight of the coarse and fine AP. The ratio of the coarse (200) AP/fine (55) AP for NSWC/IH-BC-15, NSWC/IH-BC-16 and NSWC/IH-BC-17 shall be nominally 30/70 but may be adjusted as needed. The ratio of the coarse (200) AP/fine (30) AP for NSWC/IH-BC-20 shall be no
32、minally 38/62 but may be adjusted as needed. The ratio of the coarse (200) AP/fine (10) AP for NSWC/IH-BC-21 shall be nominally 40/60 but may be adjusted as needed.

The value of this ratio shall be nominally 0.90/1.0 based on the functional equivalence values from the vendors ingredient certifications. The amoun
40、t of the HX-752 shall be nominally 0.30% and can be adjusted as needed to improve cold temperature strain properties. Total amounts of the HTPB polymer, IDPI, and HX-752 shall remain constant at 14.37 1 percent. 3.3.3.4 Binder, NSWC/IH-BC-20. Control of the physical properties of the propellant shal

44、 varying the amounts of HTPB polymer (WS 20700), Isophorone Di-Isocyanate (IPDI, MIL-C-85498) and HX-752 bonding agent. The amounts of HTPB polymer and IPDI shall be determined by adjusting the ratio of chemical equivalents of the curative (IPDI) to the chemical equivalents of the HTPB polymer. The
45、value of this ratio shall be nominally 0.90/1.0 based on the functional equivalence values from the vendors ingredient certifications. The amount of the HX-752 shall be nominally 0.30% and can be adjusted as needed to improve cold temperature strain properties. Total amounts of the HTPB polymer, IDP
46、I, and HX-752 shall remain constant at 12.85 1 percent. 3.3.3.6 Binder, NSWC/IH-BC-22. Control of the physical properties of the propellant shall be maintained by varying the amounts of HTPB polymer (WS 20700), Isophorone Di-Isocyanate (IPDI, MIL-C-85498) and HX-752 bonding agent.
