This document defines procedures for determining the standard thermal outputs and other characteristics of radiators and convectors installed in a permanent manner in construction works, fed with water or steam at temperatures below 120 °C, supplied by a remote energy source. This document specifies the laboratory arrangements and testing methods to be adopted, the admissible tolerances, the criteria for selecting the samples to be tested and for verifying the conformity of the current production with the samples tested at the initial test. This document also defines the additional common data that the manufacturer shall provide with the product in order to ensure the correct application of the products. This document does not apply to fan-assisted radiators, fan-assisted convectors and trench convectors or to independent heating appliances.

EN-IEC 62282-8-201 defines the evaluation methods of typical performances for electricenergy storage systems using hydrogen. This is applicable to the systems that useelectrochemical reaction devices for both power charge and discharge. This document appliesto systems that are designed and used for service and operation in stationary locations (indoorand outdoor).The conceptual configurations of the electric energy storage systems using hydrogen are shownin Figure 1 and Figure 2. Figure 1 shows the system independently equipped with an electrolysermodule and a fuel cell module. Figure 2 shows the system equipped with a reversible cellmodule. There are an electrolyser, a hydrogen storage and a fuel cell, or a reversible cell, ahydrogen storage and an overall management system (which may include a pressuremanagement) as indispensable components. There may be a battery, an oxygen storage, a heatmanagement system (which may include a heat storage) and a water management system(which may include a water storage) as optional components. The performance measurement isexecuted in the area surrounded by the outside thick solid line square (system boundary).NOTE In the context of this document, the term "reversible" does not refer to the thermodynamic meaning of an idealprocess. It is common practice in the fuel cell community to call the operation mode of a cell that alternates betweenfuel cell mode and electrolysis mode "reversible".This document is intended to be used for data exchanges in commercial transactions betweenthe system manufacturers and customers. Users of this document can selectively execute testitems suitable for their purposes from those described in this document.

Radiators are heating bodies which emit heat partly by radiation; convectors, on the contrary, emit heat almost wholly by natural convection. ISO 3148 specifies test installation, procedure and expression of results.

A number of suitable arrangements of test apparatus are illustrated in the annex. ISO 3147 is applicable to tests of primary circuits performed in the steady-state condition, in accordance with the specifications laid down for each type of appliance in the relevant International Standards. Where appropriate, special arrangements required for certain types of appliance may also be given in these International Standards.
