Commissioning Inspection

Commissioning Inspection refers to the technical inspection of a machine, installation or technical system before it is put into regular operation. Its purpose is to verify that the equipment has been properly installed or assembled, performs its intended functions and meets the requirements for safe operation.

In the context of EAC Certification and EAC Declaration, a distinction must be made between the Conformity Assessment of a product and its subsequent commissioning. An EAC Certificate or an EAC Declaration does not automatically replace the inspections and acceptance procedures that may be required for a specific installed system.

Commissioning Inspections are particularly relevant for:

  • machinery and industrial installations,
  • production lines and interconnected systems,
  • pressure equipment and pressure systems,
  • boiler and power generation installations,
  • electrical installations,
  • explosion-protected equipment and installations,
  • other complex or safety-critical technical systems.

The type and scope of a Commissioning Inspection depend on the product, operating conditions and applicable requirements. Relevant provisions may include the applicable Technical Regulations (TR EAEU / TR CU), technical standards, Manufacturer specifications, installation requirements and national regulations of the respective EAEU member state.

Depending on the installation, a Commissioning Inspection may include:

  • verification of correct assembly and installation,
  • functional testing and verification of operating parameters,
  • inspection of safety and protective devices,
  • testing of emergency stop and shutdown functions,
  • inspection of control and monitoring systems,
  • Pressure Testing or leak testing, where required,
  • electrical testing and measurements,
  • verification of product and safety markings,
  • review of the required technical documents.

Depending on the product, the following Technical Regulations may be particularly relevant:

For machinery, particular attention must be paid to correct installation, adjustment and the proper functioning of protective devices. For pressure equipment, leak tests, strength tests and inspections of safety devices may be required. For explosion-protected installations, the installation and actual operating conditions must correspond to the intended explosion protection characteristics and Ex marking.

An important basis for commissioning is provided by the Operating Instructions. These may contain requirements for assembly, installation, adjustment, testing, commissioning and safe operation. The Technical Passport may also contain relevant information on operating parameters, inspections and operating conditions.

Depending on the installation and applicable requirements, the results of a Commissioning Inspection may be documented in:

  • a Test Report or commissioning report,
  • measurement and inspection reports,
  • installation and acceptance documents,
  • entries in the Technical Passport,
  • other technical or operational records.

Who is responsible for carrying out the inspection depends on the installation and the applicable regulations. It may be the Manufacturer, the plant engineering company, the operator, qualified inspection personnel or an appropriately authorized inspection organization. There is no general requirement for Commissioning Inspections to be performed by an Certification Body.

A Commissioning Inspection must be distinguished from Product Testing as part of EAC conformity assessment. While Product Testing evaluates compliance with regulatory product requirements, a Commissioning Inspection focuses on the specific installed or assembled system and its condition before regular operation begins.

This distinction can be particularly important for complex industrial installations. If machinery and components are assembled into a complete system at the installation site or substantially modified, it must be determined which requirements apply to the final configuration and whether existing Proof of Conformity documents cover the equipment as actually installed.

Typical problems during commissioning include:

  • incorrect assembly or installation,
  • discrepancies between the delivered equipment and its documentation,
  • incorrectly adjusted safety devices,
  • missing inspection or commissioning reports,
  • incomplete Technical Documentation,
  • changes made during installation that have not been properly assessed,
  • missing or unsuitable operating and safety instructions.

A properly performed and documented Commissioning Inspection supports the verification of correct installation, functionality and operational safety. However, it does not replace any additional regulatory approvals or special acceptance inspections that may be required before operation begins.

We support manufacturers, machinery suppliers and plant engineering companies with regulatory questions concerning the commissioning of technical installations within the EAEU. Our services include reviewing existing EAC Conformity Documents, determining the applicable Technical Regulations, assessing the Technical Documentation and coordinating the inspection and documentation requirements for the specific installation.
