This document describes a method for determination of sorption of graded thermally treated and densified biomass fuels such as classified in ISO/TS 17225-8. Apart from pelletized materials as described in ISO/TS 17225-8, the method can also be applied to non-compressed or non-densified thermally treated biomass as specified in ISO 17225-1 Table 14 and Table 15.

This European Standard specifies methods for testing, rating of performance and calculation of water heating energy efficiency of air/water, brine/water, water/water and direct exchange/water heat pump water heaters and heat pump combination heaters with electrically driven compressors and connected to or including a domestic hot water storage tank for domestic hot water production. This European Standard comprises only the testing procedure for the domestic hot water production of the heat pump system. NOTE 1 Testing procedures for simultaneous operation for domestic hot water production and space heating are not treated in this standard. Simultaneous means that domestic hot water production and space heating generation occur at the same time and may interact. NOTE 2 For heat pump combination heaters the seasonal efficiency of space heating is determined according to EN 14825. This European Standard only applies to water heaters which are supplied in a package of heat pump and storage tank. In the case of water heaters consisting of several parts with refrigerant connections, this European Standard applies only to those designed and supplied as a complete package. This European Standard does not specify requirements of the quality of the used water.

This European Standard specifies the safety, construction and performance requirements for automatic burner control systems, programming units and flame detector devices, intended for for similar usages, with gas and oil burners and gas and oil burning appliances, with or without fans. These devices are hereafter referred to generally as "automatic burner control systems”. This European Standard is applicable to automatic burner control systems that include additional functions. This European Standard does not cover automatic burner control systems utilizing thermo-electric flame supervision devices. NOTE 1 European Standards for burners, appliances or processes which use automatic burner control systems, programming units or flame detectors can override the requirements of this standard. NOTE 2 Provisions for production control are not part of this European Standard.
