Fast heating tube test of MCX-8100 EMTAP 41 Test

The EMTAP 41 fast heating tube test has been carried out during STANAG 4170 qualification of MCX-8100. Seven tubes have been tested and all open up by a burning or degree 1 reaction with no fragmentation. The recovered tubes may be divided into two groups. Four tubes have one longitudinal crack in the center of the body. These reacted after 124+5 seconds at an outer tube surface temperature of 500+33oC. The three remaining tubes, still in one piece, have two or more longitudinal cracks in the body. For these tubes the time to reaction is 154+12 seconds with an outer tube surface temperature of 390+25oC. MCX-8100 gives a degree 1 or burn reaction for all seven tested tubes in the fast heating test. This shows a mild reaction of the MCX-8100 composition when exposed to the fast heating threat. For munitions filled with MCX-8100 the possibility to achieve IM properties should be good when exposed to thermal threats.
