Mechanical Engineering Certification & Testing

The challenges of using wireless technologies in mechanical engineering and production environments

The question of the future has always revolved around new technologies – and what they mean for us. This also applies to mechanical engineering, for which digitization and the advancing (radio) networking of machines and systems represent both challenge and opportunity in equal measure.

By equipping plants with radio technologies, manufacturers who want to bring their products to market are faced with new regulatory requirements. On the other hand, there are users of connected systems whose efficiency gains in production depending on the functionality and performance of their machinery.

Regulatory requirements and performance in use. This is a broad field in mechanical engineering in which we support our customers with advice and assistance.

cesitec and CETECOM - The ideal combination for mechanical engineering

For manufacturers and distributors of machines and systems, the Machinery Directive is initially decisive for approval. This directive primarily includes requirements that relate in particular to machine safety with regard to the operator.

With the advancing digitalization and the accompanying networking of devices, machines and production sites, the specifications for the approval of the devices are changing significantly and a wide variety of challenges arise for the performance and the reliable and safe operation of the digitalized and connected machines and systems in use.

cesitec and CETECOM as partners for the mechanical and plant engineering industry

CETECOM and our wholly owned subsidiary cesitec combine a service portfolio that addresses the challenges for the approval and use of machinery and equipment, making them ideal partners for companies in this segment.

CETECOM - Your contact in radio matters

With the changing requirement to equip plants with wireless technologies, machine builders who want to bring their products to market are facing new regulatory requirements. On the other side are users of connected plants whose efficiency gains in production depend on the functionality and performance of the machinery. This is where CETECOM joins:

Regulatory requirements and performance in use. A broad field in mechanical engineering in which we provide our customers with advice and support.

The Radio Equipment Directive (2014/53/EU) for Mechanical and Plant Engineering

Even the use of a single radio module (e.g. Bluetooth, WLAN or 2G/3G/LTE/5G) means that the Radio Equipment Directive 2014/53/EU must also be taken into account for CE marking.

The Radio Equipment Directive (RED) 2014/53/EU has been mandatory since June 13, 2017 for all radio equipment that falls within the scope of this directive. The directive has completely replaced the R&TTE directive after a transitional phase as of this date.

The scope of application addressed relates to all devices and machines that use a radio module, regardless of whether (previously) other specifications and directives are still used (e.g. the Machinery Directive).

The technologies used determine the test framework defined in the Radio Equipment Directive:

  • Electromagnetic compatibility (EMC)
    • EN 301 489-1 / and e.g. -17 for BT/WLAN or -52 for mobile communications
  • Electrical safety
    • EN 62368-1
  • Radiated Spurious Emission or other radio tests
  • Health and safety
    • EMF measurement / MPE calculation or SAR measurement depending on application resp. the distance of the machine to the body of the operator and the respective emitted power

If the underlying standards are harmonized, manufacturers have the option of drawing up a self-declaration (EU Declaration of Conformity); the involvement of a Notified Body for Radio Applications is therefore optional.

If a Notified Body is involved, it will issue an EU Type Examination Certificate for the manufacturer after checking all test reports and reviewing the submitted documents. This often facilitates the certification process for international market approvals.

Connectivity as a guarantee of success for production sites

Security, data throughput, availability – characteristics that are inseparable from an efficient production facility.

With more than 25 years of experience in connectivity and wireless networking, combined with our expertise in mechanical engineering, we are your ideal partner for networking your production facilities:

We advise you on the selection of radio modules and on the correct integration up to operational readiness.

  • In the course of network planning at your production site – e.g. for 5G campus networks or IoT networks based on ISM radio systems – we support you with network coverage measurements.
  • We perform on-site electromagnetic compatibility tests or tests based on regulatory radio standards and help with troubleshooting and advise on interference remedies.
  • Within the scope of measurements according to EMF-V (formerly BGV B11/DGUV 15/16) for occupationally exposed persons, we advise companies in order to protect their employees in the best possible way.
