    5.1 General<\/h1>\n

    The safety goals of this European Standard shall include:<\/p>\n

    – choice of materials such that the construction and operation of the system are not detrimentally affected.
    \nIn particular, all the components of the fuel pipework shall be capable of withstanding the mechanical,
    \nchemical and thermal loads to which they can be subjected during normal operation;
    \n– reliable and correct time for ignition of the fuel\/air-mixture at the burner(s);
    \n– prevention of unintentional release of unburned fuels;
    \n– shut-off fuel-supply in case of relevant fault;
    \n– protection of pipeline by precluding the propagation of flame in reverse flow;
    \n– prevent firing when the exhaust of combustion products is not ensured;
    \n– prevent firing when the process conditions are not in the safe state.
    \nElectrical circuits shall be designed in accordance with subclause 5.7 of EN 60204-1:2006.<\/p>\n

    The combustion and fuel handling for IThE shall comply with the safety requirements and\/or protective
    \nmeasures of Clause 5.
    \nMachinery shall comply with the safety requirements and\/or protective measures of this clause. In addition,
    \nthe machine shall be designed according to the principles of EN ISO 12100 for relevant but not significant
    \nhazards, which are not dealt with by this document.<\/p>\n

    NOTE For guidance in connection with risk reduction by design, see clause 4 of EN ISO 12100-2:2003, and for safeguarding measures see clause 5 of EN ISO 12100-2:2003.<\/p>\n

    1) A risk assessment is thus obligatory and additionally necessary. The application of a harmonized Standard can, however, be part of the risk assessment. <\/span><\/p>\n<\/div>\n
