    Abstract - (Show below) - (Hide below)

    Outlines the requirements and test procedures for the construction, safety and marking of gas-fired type B tumble dryers not exceeding a nominal heat input of 20 kW and with drum volume not exceeding 350 litres. Applicable to types B22 and B23 direct gas-fired, and to types B11 and B11BS indirect gas-fired appliances. Excludes: catalytic combustion appliances; appliances intended for use in locations where special conditions prevail, such as the presence of corrosive or explosive atmosphere; appliances of the condensing type; those intended for use in vehicles or on board ships or aircraft; and those of types B22D and B23D.
