BS EN 17956:2024

This standard BS EN 17956:2024 Energy efficiency classes for technical insulation systems. Calculation method and applications is classified in these ICS categories:

• 91.140.10 Central heating systems
• 91.140.30 Ventilation and air-conditioning systems
• 91.120.10 Thermal insulation of buildings

This document is applicable to technical insulation systems of operational installations in industry and the building services, such as pipes, ducts, vessels, equipment and built-in components. The document specifies methods for the energy efficiency classification of insulation systems for the abovementioned components with an operational temperature range of −30 °C up to 650 °C. The document addresses plant operators, engineers of operational installations, as well as the involved contractors such as insulation contractors and pipefitting contractors. The design of safe surface temperatures for personal protection, as well as the prevention of condensation, is outside the scope of this document. This document also does not apply to water-based heating and cooling systems in buildings and does not apply to directly buried district heating and district cooling pipes.
