TS 12845

TS 12845 is a rules standard for authorized services handling professional-purpose audio and video equipment, covering their business organization, structural features, technical equipment, staff qualifications, and certification arrangements. In practical terms, it addresses not the devices alone, but the service organizations that maintain and repair them under an authorized-service framework.

The standard’s focus is the institutional setup expected for service providers working on professional audio-video systems. In general technical terms, professional AV equipment is used in environments such as broadcasting, production, live presentation, recording, and other applications where reliability matters. For that reason, service capability depends on proper diagnosis, suitable test equipment, spare-parts control, and trained personnel.

What the standard is organized around

• Business and organizational arrangements for authorized services
• Physical and structural characteristics of the service facility
• Technical equipment and maintenance/repair infrastructure
• Staff qualifications and technical responsibility
• Certification principles
• Excludes modem devices used as computer peripherals

The standard is concerned with the authorized service structure itself rather than the internal design of the equipment being serviced. That distinction matters because professional audio and video products often require specialized measurement, troubleshooting, and repair capability that must be defined at the service-organization level. It also explicitly excludes modem devices used as computer peripherals, keeping the scope limited to professional AV service operations.

This document was withdrawn in 2016, but it remains useful for understanding how authorized-service requirements are framed around competence, organization, and continuity of technical support in the audio-video field.
