This European Standard specifies the requirements and test methods for rational use of energy of gas-fired type B tumble dryers not exceeding a nominal heat input of 20 kW and with drum volume not exceeding 350 l, hereafter referred to as "Appliances". This European Standard applies to types B22 and B23 direct gas-fired appliances and to types B11 and B11BS indirect gas fired appliances. This Standard does not apply to: a) catalytic combustion appliances; b) appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere; c) appliances of the condensing type wherein the heated air and products of combustion used for the drying process are dehumidified by cooling with water or air; d) appliances intended to be used in vehicles or on board ships or aircraft; e) appliances of types B22D and B23D. This standard covers type testing only.
