Provides assurance that recognized best practice has been employed in the selection and construction of the assembly.

Provides assurance that recognized best practice has been employed in the selection and construction of the assembly.

Technical Requirements

Assemblies of already-certified ATEX equipment require the system integrator to compile a technical file and assess the various sub-assemblies and certified products together. Notified Body services are not required under ATEX unless the assembly has been modified from its original certified design or it incorporates certified ‘U-type’ components, which must be re-assessed in the final ‘equipment’ application. However, even under the voluntary route, increasingly end users and plant operators require third-party verification of assembly compliance with international standards and recognized codes of practice.

Typical Products Include

• Enclosure systems incorporating U-type Components, certified by Unit Verification
• Skids or containerized equipment packages
• Temporary equipment packages

Accredited certification bodies such as DNV can provide third-party assessment and certification for such assemblies on a voluntary basis, ensuring recognized best practices in assembly selection and construction.
