NOTE 1
30、 A Part 18 on operating instructions is currently in preparation. Although these parts may be obtained separately, it should be recognized that the parts are inter-dependent. As such, the design and manufacture of water-tube boilers requires the application of more than one part in order for the req
31、uirements of the European Standard to be satisfactorily fulfilled. NOTE 2 Part 4 and Part 15 are not applicable during the design, construction and installation stages. NOTE 3 A “Boiler Helpdesk“ has been established in CEN/TC 269 which may be contacted for any questions regarding the application of
32、 European Standards series EN 12952 and EN 12953, see the following website: http:/www.boiler-helpdesk.din.de According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
