an ATEX zoned environment or for suctioning a flammable substance are protected in different ways to ensure that the dust filter itself does not become a source of ignition. Explosion protection Kst value (m.bar/s) Dust class (Dust) > 0 to 200 1 > 200 to 300 2 > 300 > 3 The Dustmasters that are also suitable for extraction

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).

St The Kst value is then calculated which may be used to design new explosion protection systems or verify existing designs. The test follows ISO 6184/1:1985 and BS EN 14034 Parts 1 & 2 and the results will assist in making a DSEAR risk assessment. The test can also be carried out to the American Standard ASTM E1226-05. Kst and St. Classification 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.

The fire generated by a product bearing a higher Kst will be longer and faster. 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).

Il Kst, insieme al P max (Maximum explosion overPressure), mi dà invece quanto distruttiva è una data polvere una volta che sia partita l’esplosione. Esso infatti equivale al valore numerico del massimo valore di aumento di pressione in un serbatoio nelle condizioni previste dal test, ed è misurato in bar . m / sec.

DSEAR (UK) & ATEX (Europe) are applicable for any potentially explosive substance that is found in the workplace. If the explosion hazard of the material is unknown, the classification test provides a simple means of screening to ATEX Equipment; Custom-made Solutions; Downloads; Contact; Home; ATEX Equipment; RANGE OF EXPLOSION PROOF EQUIPMENT FOR EXPLOSIVE ATMOSPHERES. EXPLOSION PROOF EQUIPMENT FOR HAZARDOUS AREAS.

Combustible Dusts - OSHA Kst, the dust deflagration index, measures the relative explosion severity compared to other dusts. The larger the value for Kst, the more.

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). bar.m/s. (dP/dt) max .V 0.33 =Kst. The value dP/dt is dependent of the volume of explosion, however, it has been found that Kst is independent of the volume and is only a function of the powder used. Thus, it is usual to use Kst rather than dP/dt to express the explosion properties of powders.

*Kst the maximum rate of pressure rise is used to calculate the Kst value; an internationally recognized. Kraft_Lignin.pdf.

however, and any material with a Kst value greater than zero is considered to be at risk of an explosion.

The test can also be carried out to the American Standard ASTM E1226-05.
