Quite often equipment is supplied or operated in a combination with other equipment or components, in other words, we are dealing with single functional units (assemblies) in the scope of Directive 94/9/EC, for example products such as:

• Valves and their operating gears
• Pumps
• Fans

But also complete plants may perform assemblies, including safety, control and regulating units; for example:

• Belt conveyor systems including drives and controls
• Elevators
• Dedusting equipment/filtering systems
• Silos
• Packaging machines
• Electropneumatic controls
• Sampling systems

Special ATEX requirements on systems and plants

DEKRA EXAM GmbH supports manufacturers of such plants and systems (assemblies) as part of the conformity assessment process regarding the following aspects:

• 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 processes
• Use of components without CE marking
• Special requirements on the documentation (e.g. instruction manual) of assemblies

Customised solutions for plants and systems

In addition to that, DEKRA EXAM GmbH offers simple and compelling solutions to manufacturers who want to assemble customised plants by combining several components to modular systems:

• Individual agreed conformity assessment processes
• Optimal amount of formal efforts
• Flexibility when modifying or supplementing the system

Plants protected by construction

The supply of explosion-proof plants – i.e. plants resistant to impact and pressure in case of explosion e.g. filter systems, separators, mills or scales – includes also plants with protective systems in place such as relief systems; for these plants special requirements according to Directive 94/9/EC have to be observed. Here DEKRA EXAM GmbH supports manufacturers regarding:

• Individual agreed conformity assessment processes
• Conducting the tests needed (explosion test, water pressure test, etc.)
• Simulation of calculations (e.g. finite element calculations to assess enclosure strength)
