（CA20L）20L EXPLOSION CHAMBERS FOR GAS AND DUSTS

Explosion chambers are used for the measurement of the basic explosion characteristic of flammable dusts, gases and vapors. The characteristics measured are the maximum explosion pressure, the maximum rate of pressure rise, the lower and upper explosibility limits and limiting oxygen concentrations.

APPLICATION

Two sizes of explosion chambers are mandated by international standards for dust explosion testing– 1 m3 (our CA 1M3) and 20 l (our CA 20L). For gas and vapor samples which require a volume larger than 5 l the CA 20L is recommended. Testing methods using the CA 1M3 and the CA 20L are an essential part of a standard set of tests used by certified bodies, Universities and other research organizations to characterize dust, gas and vapors. Design of mitigating and protective measures such as explosion venting devices, automatic suppression or partial inerting, without knowledge of these explosion parameters is unimaginable.

COMPLIANCE

•   EN 14034 (1-4) sets up 1 m3 explosion chamber (our CA 1M3) as a standard instrument for measurement of maximum pressure, rate of pressure rise, lower explosion limit (LEL) and   limiting oxygen concentration (LOC) of dust dispersions. 20 l sphere (our CA 20L) is an alternative of 1 m3 explosion chamber given by EN 14034 (1-4)

•   Both CA 1M3 and CA 20L could be delivered with instrumentation for measurement of explosion parameters of gases and vapors according to EN 15967 (maximum pressure and rate of pressurerise), according to EN 14756 (LOC) and EN 1839 (explosion limits)
