Nanotechnologies. Characterization of multiwall carbon nanotubes. Mesoscopic shape factors PAS 015 BS 5421-2 describes eight methods1 Scope This European Standard applies to boilers used for central heating (heating boilers) with forced draught burners with a nominal heat output not exceeding 1 000 kW, which are operated either with negative pressure (natural draught boilers) or with positive pressure (pressurized boiler) in the combustion chamber, in accordance with the boiler instructions. This European Standard specifies the necessary terminology, the requirements on the
