TS 12853

TS 12853 is a service standard dealing with the rules for authorised services that support typewriters, calculators, money counters, data-bank equipment, paper shredders and electronic blackboards and similar office and service machines. It addresses the service organisation as a whole, including management structure, technical facilities, staff characteristics and the rules related to certification.

What the standard focuses on in a competent service setup

Standards of this kind are not mainly about repairing a device in isolation; they are about whether a service centre can deliver maintenance and repair work in a consistent, traceable and organised way. Management structure covers roles, responsibilities and operating order. Structural properties relate to the physical conditions and workplace arrangement needed to provide the service properly.

Technical equipment refers to the tools, measurement and inspection capabilities needed to carry out service work. Personnel characteristics concern whether technical managers and staff have the competence to identify faults, perform maintenance and support the relevant equipment group. In this context, certification matters because it defines how authorised service status is established and maintained.

How the scope separates the equipment classes

• The standard brings together common service rules for different office and business-use machines under one framework.
• It covers both mechanical and electronic systems such as typewriters, calculators and money counters.
• It also includes devices with different functions, such as paper shredders and electronic blackboards.
• In general technical terms, service quality for these machines depends on correct diagnosis, suitable spare parts, safe intervention and functional verification.

The focus of the standard is the organisation of the authorised service, not the design of the products themselves. Technically, that means the emphasis is on the adequacy of the service infrastructure and the reliability of the maintenance process rather than on the internal construction of each machine.
