1 Scope
1.1 This standard (Part 1/Sec 1) stipulates materials and loads to be adopted in the design of self-supporting steel lattice towers for overhead transmission lines.
1.1.1 Permissible stresses and other design parameters are covered in IS 802 (Part 1/Sec 2 ) : 1992 of this standard.
1.1.2 Provisions on fabrication including galvanizing, inspection and packing, etc, and testing of transmission line towers have been covered in IS 802 (Part 2) : 1978 and IS 802 (Part 3) : 1978 respectively.
1.2 This standard does not cover river crossing towers and guyed towers. These will be covered in separate standards.
