Decibels[edit]

Can I suggest using the full word "decibels" rather than dB, and linking to http://en.wikipedia.org/wiki/Decibel#Acoustics rather than the main article about logarithmic units, which is not helpful here. Mat Teja (talk) 09:49, 11 April 2012 (UTC)

Agreed, done. (Hohum @) 21:53, 11 April 2012 (UTC)

"Subsonic deflagration"[edit]

The M84 contains 4.5 g of a modfied (hydrofobized, stabilised etc.) micronised Magnalium + Perchlorate flash composition. This type of pyrotechnic mixture (MgAl-Perchlorate flash) does not deflagrate, it does in deed detonate, i.e. the reaction upon ignition does propagate throughout the charge with supersonic speed in a sharp high-pressure front. The reason for the relatively low brisancy (shattering capacity) of the M84 is
i) the small charge (explosive yield slightly above a single standard No.8 blasting cap) and
ii) that the composition, despite being quite exothermic, produces very little gas; almost all reaction products are solids or liquid particles.
The limited concussion is caused primarily by the intense heat impulse, superheating the air gap within the massive perforated steel body of the grenade. This type of pyrotechnic compositions (Mg/Al+Chlorate/Perchlorate/Nitrate flash compositions) are also classified as high explosives (means detonation capable) by the official dangerous goods classification schedules.
