Provides assurance that recognized best practice has been employed in the selection and construction of the assembly.
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 a third-party verification of the compliance of such assemblies to international standard 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 to provide assurance that recognized best practice has been employed in the selection and construction of the assembly.
