Vi hjælper også gerne din virksomhed med at finde de rigtige løsninger, således ATEX-kravene er tilgodeset. Nedenfor er mere specifik information, men kontakt os gerne på Teknologisk Institut udfører de tests, som kræves i relation til ATEX-direktivet 2014/34/EU samt de tests, som er relevante i forbindelse med en ATEX-APV. Det kunne fx være fastlægges af diverse parametre for det ”støv”, der kan give anledning til en eksplosiv atmosfære i produktionen.Vi gennemfører også relevante tests i ATEX-standarderne. 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.

To prevent this from happening, Ex-Machinery developed a special ATEX heater that dries the The ATEX directive 2014/34/EU evaluates these zones as follows: ATEX Zone 20: high probability of explosive atmosphere (over 1000 h/year) ATEX Zone 21: average possibility of explosive atmosphere (between 10 and 1000 h/year) ATEX Zone 22: low possibility of explosive atmosphere (under 10 h/year) In particular, TAMA AERNOVA is capable to manufacture 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.

The ATEX directives also include hazards from mechanical sources and therefore the equipment scrutinized and regulated will be diverse. It is the owner/operators responsibility to determine the risk of possible explosion in his premises and a risk assessment must be carried out to allow him to declare his zones under ATEX directive 1999/92/EC, to comply with DSEAR regulations.

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. Kst, aka the dust deflagration index, is one of the parameters used to quantify the severity of a dust explosion.

However, the tea leaves generate fine dust particles which, when airborne, may cause dust explosion hazards. To prevent this from happening, Ex-Machinery developed a special ATEX heater that dries the The ATEX directive 2014/34/EU evaluates these zones as follows: ATEX Zone 20: high probability of explosive atmosphere (over 1000 h/year) ATEX Zone 21: average possibility of explosive atmosphere (between 10 and 1000 h/year) ATEX Zone 22: low possibility of explosive atmosphere (under 10 h/year) In particular, TAMA AERNOVA is capable to manufacture 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.

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.

limit (LEL), Kst value the company is required to take steps according to ATEX 137. Critical safety measures: • Zone division depending on the explosion risk • Labelling hazardous areas • Determine which protective actions to implement • Operation instructions for employees • Creating an explosion prevention The maximum rate of pressure rise can be measured on the pressure vs time graph (see above) and then Kst calculated knowing the volume V of the test vessel : (dP/dt) max = Kst.V-0.33 [Laurent] Kst is expressed in bar.m/s. Depending on the value of Kst, powders can be classified in classes. St1 : 0 < Kst < 200 Der K St -Wert ist eine staub- und prüfverfahrensspezifische Kenngröße, die zusammen mit dem maximalen Explosionsüberdruck das Reaktionsverhalten eines Staubes charakterisiert. Der K St -Wert wird aus der maximalen Druckanstiegsgeschwindigkeit mit Hilfe der folgenden Formel ermittelt, die als kubisches Gesetz bezeichnet wird.
