The thermal activation device shall be capable of operating at a rated temperature and arranged to initiate the aerosol-forming compound.Other methods of activation device. Methods capable to initiate the aerosol-forming compound, other than 4.4.2 and 4.4.3, shall be specified by the manufacturer.End plate and housing. The outer case and all parts inside the generator shall be made of corrosion-resistant material or shall be suitably treated to resist corrosion. The manufacturer shall ensure that the materials of construction are also compatible with the solid aerosol-forming compound and the cooling device so that corrosion or chemical action does not adversely affect performance. Materials for non-metallic components that are exposed to ultraviolet light shall be UV-stabilized. The housing shall be designed so that the function cannot be adversely affected by ageing or environmental influences. Non-metallic materials and elastomers shall be selected to be stable and not alter their performance over the working life recommended by the manufacturer.The test samples shall conform to the technical description (drawings, parts list, description of function, operating instructions) as stated by the manufacturer (see 5.17 and 7.3). The manufacturer shall specify the minimum distance from the generator outlet to the first obstacle. The manufacturer shall specify the minimum and maximum mass of aerosol compound discharged from the generator.The service life of condensed aerosol generator under specific conditions, as described in 5.5, shall be specified by the manufacturer and as a minimum requirement shall not be less than 15 years. The specified service life shall be verified by test using the accelerated ageing test as described in 7.7.The selected unit sizes shall be appropriate for the protected area in terms of the minimum thermal clearance from the discharge outlets. The following general criteria shall apply: for locations where personnel can be situated, the minimum thermal clearance shall refer to a temperature not exceeding 75 °C; for locations where combustible materials or equipment can be situated, the minimum thermal clearance shall refer to a temperature not exceeding 200 °C;  for locations where non-combustible equipment can be situated, the minimum thermal clearance shall refer to a temperature not exceeding 400 °C.BS EN 15276-1 pdf download.
