Certifying testing bodies

Businesses wishing to act as testing bodies to carry out interoperability tests for public safety digital radio equipment and for public safety digital radio control centres may apply for certification, if they have the necessary know-how, independence and objectivity to conduct interoperability tests for public safety digital radio terminal equipment in a structured and clear manner.

Testing bodies must fulfil the following requirements:

  • Compliance with the applicable standard DIN EN ISO/IEC 17025:2005

Requirements for conducting interoperability tests for public safety digital radio equipment:

  • Experience with existing systems and regulations governing the non-public land mobile service of public safety agencies (analogue PMR, Public Safety Digital Radio Regulation),
  • ETSI mobile radio standard TETRA and already existing TETRA radio systems,
  • Trunked radio, GSM and DECT as similar radio communications technologies,
  • Know-how and long-standing experience in testing protocols in telecommunication systems, especially radio communications systems,
  • Know-how and long-standing experience in operating interoperability platforms and their use and maintenance as part of certification tests,
  • Know-how and long-standing experience in similar areas such as

    • electromagnetic compatibility,
    • electrical safety,
    • health and
    • usability to assess potential vulnerabilities and risks,
  • Experience with applications using cryptographic functions (specifically: TETRA-radio interface encryption and authentication procedures, end-to-end encryption, key management systems),
  • Experience in developing and setting up test environments and
  • Experience in validating test specifications and test environments.


Requirements for conducting interoperability tests for public safety digital radio control centres:

  • Knowledge of and experience with public safety control technology and systems,

  • Know-how and long-standing experience in operating interoperability platforms and their use and maintenance as part of certification tests,
  • Know-how and long-standing experience in similar areas such as

    • electromagnetic compatibility,
    • electrical safety,
    • health and

  • Experience with applications using cryptographic functions (specifically: TETRA-radio interface encryption and authentication procedures, end-to-end encryption, key management systems),
  • Experience in developing and setting up test environments and
  • Experience in validating test specifications and test environments.

Furthermore businesses wishing to act as testing bodies for carrying out interoperability tests for public safety digital radio must be willing to comply with or already fulfil the industrial security procedures of the Federal Ministry of Economics.

Responsibility for certifying testing bodies

A certificate confirming that the above-mentioned requirements have been met can be obtained from the Federal Office for Information Security (BSI).

The certification of testing bodies to carry out interoperability tests for public safety digital radio equipment and for public safety digital radio control centres is not limited to one business or a specific number of businesses.

Further information can be obtained directly from the BSI:
