Explosion-proof devices according to DIN EN 14460

For the safe commissioning of components in the field of apparatus and plant engineering, equipment and protective systems for use in potentially explosive atmospheres that fall within the scope of Directive 2014/34/EU must comply with general health and safety requirements according to Annex II from Directive 2014/34/EU. If the special technical requirements in DIN EN 14460-2018 are met, the general requirements from 2014/34/EU are fulfilled due to the presumption of conformity by publication in the Official Journal of the European Union.

With the help of the FEM calculation, we perform verifications for explosion-proof devices in the scope of DIN EN 14460 for our customers, which in turn uses the computational methods of DIN EN 13445-3. Both explosion pressure resistant designs (without permanent deformation) and explosion pressure shock resistant designs (with permissible permanent deformation) can be examined.


Your advantage through calculation

With the help of FEM calculation methods, even complex components from the field of apparatus and plant engineering can be checked and optimized with regard to strength. The direct method according to DIN EN 13445-3 Annex B represents, among other things, with the plastic calculation of the load capacity verification, an efficient method for the evaluation, since a time-consuming stress categorization can be dispensed with.


Documentation of the calculation results

Depending on the customer’s requirements, the documentation of the calculation results is carried out as a verifiable calculation report in German and English or in the form of a short documentation. In consultation with you, we will be happy to present the results that are important for you in a clear and comprehensible manner in a personal meeting.
