TS 12843

TS 12843 is a service standard for competent services that work on water treatment devices and systems. It brings together requirements related to service organisation, technical equipment, and personnel characteristics, creating a common framework for servicing both small household units and larger industrial water treatment installations.

Service organisation and technical competence

The technical idea behind this standard is that a service provider for water treatment equipment must be competent not only in name but also in operating structure. In general technical terms, water treatment devices may use filtration, activated carbon, ion exchange, membrane technologies, or similar processes to improve the physical and chemical properties of water. Service competence therefore matters for diagnosis, maintenance, spare-part handling, and a documented working practice.

Defined boundaries of the scope

TS 12843 excludes sewerage treatment systems and devices. This boundary is important because potable-water and process-water treatment differ from wastewater and sewerage treatment in equipment, operating conditions, and technical responsibilities. The standard focuses on the characteristics of competent services, especially personnel and technical facilities, rather than defining the performance of the treatment equipment itself.

• Small-capacity household water treatment devices
• Industrial water treatment systems
• Organisational structure of competent services
• Technical equipment and working arrangement
• Personnel qualifications and technical responsibilities
• Sewerage treatment systems are excluded
