25、(E) DIN EN 16855-1:2017-05 5 Introduction The drafting of this 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 per
26、formance 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. It also aims to identify the reference standards for calculation, measurement of insulation properties, to ident
27、ify 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. EN 16855-1:2017 (E) DIN EN 16855-1:2017-05 6 1 Scope This European Standard applies to prefabricated walk-in cold room
28、 kits and components. It 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
29、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 t
30、o be: installation inside an existing building; not exposed to external weather conditions. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
