Access door for easy vent panel replacement. The explosion severity test is conducted to determine maximum pressure (Pmax), Maximum rate of pressure rise ( (dP/dt)max) and Kst of an ignited powder, dispersed in air, as a dust cloud. Working through a range of powder concentrations, the powder is dispersed into a 20L explosion vessel (sphere) using, dry compressed air. These suspended dust ATEX-compliant dust removal filters 1. Features-Explosion protection is stipulated for combustible dusts by the 94/9/ EC Directive.- Dust constant (Kst value) corresponding to the approval for the decoupling elements Explosion decoupling must be provided for the dust removal fil- However, it is believed that particles with diameter greater than 500 μm have a low explosion tendency: this value is often assumed as limit beyond which a dust can’t explode.

The Kst value is then calculated which may be used to design new explosion protection systems or verify existing designs.

Furthermore, Kst value, minimum possible variation, the deflagration index values can va ry by situation. Testing should be done on the exact material being processed to accurately determine its K St. Table 3 lists some common organic and metal dust K St values.

From the tests, the arithmetic mean of the maximum values (both maximum pressure and maximum rate of pressure rise) is obtained. The Kst value is calculated as the equivalent pressure in a 1 m 3 sphere from the cube law (Kst value = cube root of volume x explosion pressure rise).

It is the equivalent of the explosion class given to the highest value describing the pressure rise in a closed vessel which is determined under specific test conditions, and expressed in bar Kst-value for classification into dust explosion classes St 1, St 2 and St 3. Examples of explosion parameters: Explosion pressure and explosion severity The dust explosion classes are the basis for designing constructive protection measures in addition to the maximum explosion pressure pmax. Dust explosion classifications Explosion pressures are measured for a range of dust concentrations using piezo-electric pressure transducers.
