IEC 60794-3-40:2008 is part of IEC 60794 family specification that covers sewer cables and conduits for installation by blowing and/or pulling in non-man accessible storm and sanitary sewers, also applicable for man-accessible and lateral ones. Systems built with components covered by this standard are subject to the requirements of sectional specification IEC 60794-3. This publication is to be read in conjunction with IEC 60794-1-1:2011, IEC 60794-1-2:2003 and IEC 60794-3:2001.
