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.

Kst ist the main parameter to apply to the measurement of the explosion vents or for the explosion suppression. Actually, a rapid rise of pressure makes it compulsory to adopt larger vents or to manufacture a vessel with a higher resistance to the rise of pressure. 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 larger the value for Kst, the more. TILBUDSFORMULAR TIL ROTORSLUSER I ATEX-ZONE. Udfyld nedenstående formular med så mange oplysninger, som muligt.

Kst and St. Classification Vad är ATEX? På 90-talet stiftades 2 st nya lagar, som påverkar vilken utrustning, som får finnas i områden med risk för gas- eller damm-explosion. ”Produktdirektivet” kom till 1994, och ”Arbetsdirektivet” kom till 1999. 2019-03-27 · This value helps you determine both your risk and the actions you need to take to minimize the chances of an explosion. However, it can be misleading. In particular, people often mistakenly assume that a low K st value means they’re in the clear. Here are two things you need to know about K st values.

all suction side ducts that transport material with a kst value above zero is an NFPA requirement. the ATEX Directive and DSEAR (2002) regulations. The system design incorporated explosion protection suitable for a dust with a KST value < 200bar.

More simply put, these data values tell you how much pressure an explosion will … according to ATEX guidelines Safe extraction and separation of explosive dust • Metallic dust • Organic dust • Paint and spray dust parameter Kst-value for classification into dust explosion classes St 1, St 2 and St 3. Examples of explosion . parameters: Explosion pressure . however, and any material with a Kst value greater than zero is considered to be at risk of an explosion. Other than silicon or sand, every kind of dust is potentially combustible to some degree.
