Explosion pressure

Under explosion pressure is defined as the determined under specified conditions pressure , which in a closed space in the explosion occurs in a potentially explosive environment at a certain composition. The explosion pressures are referred to as excess pressures in relation to atmospheric pressure (1 bar). ${\displaystyle p_{\mathrm {exp} }}$

Expected explosion pressure

The explosion pressure to be expected is the maximum pressure that can occur in a part of the system with an implemented protection concept (taking into account the given systems , processes and all operating parameters and conditions). The expected explosion pressure cannot be higher than the maximum explosion pressure , unless there is a pressure in the system that is higher than normal pressure (1 bar). ${\displaystyle p_{\mathrm {erw} }}$ ${\displaystyle p_{\mathrm {max} }}$

Maximum explosion pressure

The maximum explosion pressure denotes the highest determined explosion pressure under the conditions given above.
