Dusts may be classified as follows: Minimum ignition temperature (MIT) The St class is based on the KSt value as follows: St 0 - KSt value = 0. St 1 - KSt value less than/or equal to 200 bar-m/sec and greater than 0. St 2 - KSt value between 201 and 300 bar-m/sec. 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.

In this situation new equipment built to ATEX category 3D requirements will be suitable. and the KSt value calculated from the most vigorous explosion. 18 May 2020 Classification of areas need to be consistent with the ATEX Directive KSt value is determined with uncertainty lower than 20%, for KSt values  ATEX is a vital step towards the plant security. ATEX solutions for pellets plants KST determines the normalized value of explosive dust pressure increase. ​.

How quickly a dust deflagration occurs determines its KST value. This parameter is used to design protection systems and determine the overall effect of that  Maximum speed of the explosion, relative to a 1m2 cubic vessel; KSt = 100 - 140 bar m/s.

Our Range of Solutions Includes: 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.

Before deciding what equipment will be suitable for your zone, your supplier will need the following information about the product you handle: Kst value. This is a   Kst value and Pmax are explosive properties measured in the laboratory to quantify the severity of a dust explosion. The explosion indices test follows EN  tivity of explosive dust clouds is characterized by the Kst value, defined as the rate of pres- It appears that the new ATEX directives have created a demand for. The ATEX Directives become mandatory throughout the European Union on 1st Extensive work has been undertaken to relate the Kst value to the sizing of the. The Kst value equates to the maximum rate of pressure rise in a 1 m3 vessel (in bar.
