TS 12871

TS 12871 addresses the rules for competent services that work on rectifiers and/or inverters. Its focus is not the internal design of the equipment itself, but the way the service organisation is run: management practices, structural characteristics, technical facilities, personnel competence, and certification-related arrangements.

Core elements of a competent service setup

In general technical terms, rectifiers convert electrical power into direct current, while inverters convert direct current into alternating current in many common applications. Service work on this type of power-electronics equipment typically involves understanding control circuits, protection functions, cooling arrangements, connection integrity, and fault diagnosis. A competent service therefore depends on qualified staff, suitable measuring and test equipment, controlled workflows, and proper documentation.

Service framework covered by the standard

• Management and service organisation
• Structural characteristics and physical facilities
• Technical equipment and service tools
• Personnel requirements and technical responsibility
• Certification-related rules

In practical terms, TS 12871 supports a service model where rectifier and/or inverter maintenance is carried out within an organised and technically controlled framework. For the electrical and electronics service sector, a well-structured service organisation matters for consistent maintenance, reliable fault repair, and traceable service delivery.
