Explosive substance

Japanese: 爆発性物質 - ばくはつせいぶっしつ(英語表記)explosive substance
Explosive substance
A substance that is in a thermodynamically unstable equilibrium state, and when a certain amount of energy is applied, it undergoes a physical or chemical change (explosion), causing a sudden increase in pressure around it. It is also called an explosive. Among these, those whose explosive power can be used industrially are specified as explosives in Japan. In order to recognize the danger of explosive substances, their detonation propagation, explosive power, thermal decomposition intensity, combustion intensity, transition from combustion to detonation (roar), and various sensitivities are tested and evaluated. [Yoshida Tadao]

熱力学的に不安定な平衡状態にある物質で,ある程度のエネルギーが与えられると物理的または化学変化(爆発)を起こして,周囲に急激な圧力の上昇を起こすもの。爆発物とも呼ばれる。そのうち爆発力を工業的に利用しうるものが,日本では火薬類と規定されている。爆発性物質はその危険性を認識するために,伝爆性,爆発威力,熱分解の激しさ,燃焼の激しさ,燃焼から爆ごう(轟)への転位,種々の感度などが試験,評価される。【吉田 忠雄】
