DIN EN 50465 VDE 0130-310:2015-06

This European Standard specifies the requirements and test methods for the construction, safety, fitness for purpose, rational use of energy and the marking of a micro combined heat and power appliance; (hereafter referred to as “mCHP appliance”).
This European Standard applies to mCHP appliances of types B22, B23, B32, B33, B52, B53, C1, C3, C42, C43 C52, C53, C62, C63, C82, C83 and C9 based on the classifications of CEN/TR 1749
This European Standard does not contain the requirements necessary for appliance capable of producing electrical energy without using the thermal energy.
This European Standard does not cover all the requirements for mCHP appliances that are intended to be connected to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Aannex DD).
