TS 13640

TS 13640 is a standard focused on how competent services for heat cost allocators, heat meters and prepaid heat meters should be organised, and on the minimum organisational and technical conditions they need to meet. It addresses the service provider itself rather than the measuring devices as products, covering the service structure, staff qualifications, technical equipment and certification arrangements.

What the standard considers in a competent service

In general technical terms, the standard brings together management arrangements, premises and organisational structure, suitable equipment, personnel qualifications and certification. Because heat meters and heat cost allocators are used in the allocation of central heating and domestic hot water expenses, service activities around them need to be carried out in a way that protects measurement reliability and procedural consistency. For prepaid calorimeter systems, the service function becomes even more important in terms of continuity of measurement and operation.

Technical meaning in the context of heat metering

A heat meter measures thermal energy consumption, while a heat cost allocator supports expense distribution between apartments or use units in central systems. Prepaid systems connect usage to a preloaded balance or credit model. These differences show why competent service work is not limited to routine maintenance: the service may need type-appropriate installation, checking, adjustment, verification support and document control. TS 13640 is concerned with establishing that service infrastructure in a reliable, orderly and traceable way.
