BS EN 68551-1 is the first part of the BS EN 68551 series of standards that applies to prefabricated walk-in cold room kits and components. BS EN 68551-1 provides test or calculation methods to assess thermal insulation performances under normal end-use conditions. Performance characteristics of walk-in cold rooms are to be assessed in terms of thermal insulating properties, in order to give a basis on which assessing energy consumption related properties of walk-in cold rooms, and of their components. Performance characteristics are to be assessed for every single component of the walk-in cold room, and for the assembled walk-in cold room as a whole.
The normal end-use conditions of a walk-in cold room are considered to be:
BS EN 16855 on walk-in cold rooms is useful for:
Walk in cold rooms are thermally insulated enclosure kit made of prefabricated sandwich panels intended for the storage of chilled and/or frozen perishable items, accessible via at least one door, and which is large enough to let somebody walk in it. BS EN 16855-1 European Standard was driven by the necessity to compare the systems placed on the market on the base of the minimum thermal insulation requirements and to establish the average level of energy consumption for a future minimum energy performance standard definition, with reference to the EU policy on increasing energy efficiency of energy related products (Directive 2009/125/EC) in the frame of the EU “20-20-20” targets. BS EN 16855-1 also aims to identify the reference standards for calculation, measurement of insulation properties, to identify the best practice rules for elimination of thermal bridges, assembly techniques and provisions to be taken in order to ensure the best level of insulation and power consumption.
