Reusable for pressure rise parameters (KST values) up to 250 bar x m/s. It can be curved to vessel radius, thereby avoiding the possibility of material accumulating in front of the explosion panel. Equipped with inspection windows for easy inspection. Access door for easy vent panel replacement.

Explosion protection is regulated by the ATEX directive, which is divided into the ATEX Product Directive 2014/34/EU and the ATEX Operating Directive 1992/92/EC. The term " explosion " is understood to mean a chemical reaction or a physical process in which temperature and pressure increase considerably in a very short time (a few milliseconds).

Kst (bar-m/s) is a measure of relative explosion severity compared to other dusts while Pmax (bar) measures the maximum explosion pressure of the dust. Donaldson Torit Model DFE 4-16 dust collector handling a hybrid mixture pictured with explosion venting and isolation suppression system installed. In deze film ziet u het effect van een stofexplosie van een product met een kst-waarde minder dan 200 (stofklasse 1) . (bv bloem, meel, mais, graan.)

Atex kst value

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.

ATEX General information on explosion protection KSt value. This is a classification value which expresses the shattering effect.

Size 7"-28" are rated for Class ST 3 applications - Kst max 400 bar m/s. Pred 0.50 bar.

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.

Tomas är en av Sveriges och Europas främsta experter inom området maskin-, process- och anläggningssäkerhet. Han har lång praktisk erfarenhet av olika typer av anläggningsprojekt i de flesta medlemsländer inom de flesta branscher och anlitas av många företag för såväl riskanalyser, -kontroller, projektsupport, utbildning och Dust testing laboratory We are a UK based company offering a full range of dust explosion tests to determine the hazardous properties of particulates. For those materials where the explosive nature of the dust is in doubt, our classification test to EN ISO/IEC 80079-20-2 exposes the material to 4 different ignition sources to determine flammability; 10KV electric spark ignition, hot coil De même, les autres composants installés sur le filtre, tels que le réservoir, le séquenceur, les sondes de niveau et de température et les éléments filtrants (manches et cartouches) doivent être adaptés et certifiés conformément à la réglementation ATEX. Attention: la subdivision est un élément essentiel de la directive ATEX. ATEX: Term used to describe the legal requirement for explosive atmospheres in Europe (or a contract specification outside Europe).May refer to equipment (ATEX 95) or the protection of Workers from Potentially Explosive Atmospheres (ATEX 137) depending on the context.

3 The Kst value is calculated as the equivalent pressure in a 1 m sphere from the cube law (Kst = cube root of volume x explosion pressure rise), as previously described. For St3 rated materials, the actual explosibility – kSt should be known in order to determine the nature and capacity of necessary protective devices for ATEX compliance. The ATEX zone classification of the areas into which the machinery will be installed will be required and this is the responsibility of the owner/employer/operator. 2008-10-30 Closed plant and equipment handling flammable materials in powder form carries a risk of explosion whenever the particle size is less than 0.5 mm. Minimizing this risk places stringent demands on equipment manufacturers and plant operators.
