About Explosion Protection Services
DEKRA is a recognized European Notified Body for testing, assessments and certification of products designed to work in dangerous atmospheres or in potentially explosive environments, including petrol stations, gas containers or combustion energy transportation and storehouses. Our explosion safety specialists assess and certify according to the ATEX Directive 2014/34/EU, among others. Additionally, we are a founding member of the globally acknowledged IECEx scheme, through which we provide services both as a certification body (ExCB) and as a testing laboratory (ExTL). DEKRA is a UK Approved Body to deliver UKEX certification. This accreditation allows DEKRA to deliver UKCA marking under the UKEX scheme for market entry into Great Britain.
DEKRA offers one-stop certification to our clients, combining actions to prevent duplication of activities. DEKRA’s explosion protection test results are internationally accepted, providing our customers with a firm foundation for operating on a global scale. DEKRA is acknowledged by and collaborates with many national test and approval centers including FM Approvals, USCG and MSHA in the US, NEPSI and CQST in China, NANIO CCVE in Russia, and KTL, KOSHA and KGS in the Republic of Korea.
We test amongst others:
Equipment, components and protective systems used in hazardous areas
As a Notified Body in the Netherlands and Germany, DEKRA tests and certifies non-electrical equipment of Group I (mining) and Group II (industrial) according to Directive 2014/34/EU as well as in line with the mechanical IECEx standards. We guide manufacturers and suppliers through the whole process, from choosing the best process for assessing conformity to issuing the pertinent EC declaration of conformity.
When operating equipment assemblies (plants) in potentially explosive atmospheres, the implementation of preventive explosion protection measures is not enough to exclude explosion hazards. Constructive explosion protection always has to include an explosion-proof design of the plant in combination with explosion-protected decoupling.
Constructive explosion protection requires the use of so-called protective systems. The ATEX Directive 2014/34/EU specifies the minimum requirements for protective systems and the conformity assessment process for the EU market.
Examples of protective systems that DEKRA tests and certifies include:
Systems for pressure relief, such as explosion vents and rupture discs
Systems for suppressing explosions
Systems for explosion decoupling, such as flameproof rotary feeders, quick-closing gate valves, explosion protection valves, extinguisher barriers, double-flap valves, swing-type check valves, relief pipes and squeeze valves
Quite often, equipment is supplied or operated in combination with other equipment or components. These are often considered as single functional units (assemblies) in the scope of the Directive 2014/34/EU, IECEx 02 and INMETRO. Examples of such products are valves and their operating gear, pumps and fans. Complete plants may also be marketed as an assembly or a functional unit (like a device according to RL 2014/34/EU). For this, they need to be evaluated according to their ignition hazard, also in interaction with separate parts.
At DEKRA, we offer the following services to manufacturers of such plants and systems (assemblies) as part of the conformity assessment:
Risk assessment for the assembly regarding additional ignition hazards and other relevant risks
Test of safe use of bought-in ATEX products
Assessment of electrostatic ignition hazards at plants and within processes
Use of components without CE marking
Special requirements in the documentation (e.g. instruction manual) of assemblies
In addition, DEKRA offers solutions to manufacturers who want to assemble customized plants by combining several components into modular systems.
Knowing the flame and explosion characteristics of combustible dusts is necessary for safe handling. The type and volume of the tests are always adapted to each specific case (e.g. plant, procedure, process conditions and organizational measures). In particular, processes of segregation or enrichment of fine dust have to be considered.
DEKRA offers packages of parameter determination such as maximum explosion pressure, Kst value, minimum ignition energy and further examinations such as assessment of electrostatic ignition sources, explosion propagation modeling and investigations into causes of explosions.
Service facilities which overhaul, repair and modify equipment used in hazardous areas need to ensure continued safe operation of equipment. The IECEx 03 Certified Service Facilities scheme provides an international program for assessing and certifying explosion-related service facilities according to the requirements of IEC 60079-14, IEC 60079-17 and IEC 60079-19.
IECEx 03 enables you to demonstrate that your workshops fulfill these requirements and that you have an effective quality management system in place. The scheme also helps you to market your services internationally, as it is accepted by all IECEx countries. DEKRA is a Certification Body for IECEx 02,03,04,05 and ExCB. We work with many standards and approval bodies to help you to export your products and services worldwide.
