    Abstract - (Show below) - (Hide below)

    Provides users of pyrogen fire extinguishing aerosol systems with specific requirements for the control of fires of Classes A, B, C or F and E type.

    Scope - (Show below) - (Hide below)

    This Standard sets out requirements for design, installation and commissioning of fire extinguishing systems utilizing SOYUZ pyrogenically generated fire extinguishing aerosol for use as single or multiple systems for total flooding applications in normally unoccupied areas. The SOYUZ pyrogenically generated fire extinguishing aerosol shall be generally referred to as Pyrogen in this Standard.
