    Abstract - (Show below) - (Hide below)

    Describes the essential requirements for equipment and protective devices for a water-tube boiler plant as defined in EN 12952-1, to ensure the boiler operates safely within the allowable limits (pressure, temperature, etc.).

    Scope - (Show below) - (Hide below)

    This Part of this European Standard specifies the requirements for equipment for steam boilers and hot water generators as defined in EN 12952-1, wherein steam or hot water will be generated. Requirements for equipment for chemical recovery boilers are given in Annex A, and design examples for hot water generating systems are given in Annex B.
