To prepare International Standards for Overhead Lines above 1 kV AC and 1.5 kV DC Nominal Voltage, excluding railway traction supports and line materials.

These Standards will provide design criteria that may serve as a guide to national regulations differing from each other only in the local conditions and in the assumed safety level.

These Standards will deal with mechanical loadings and strength of the line, with clearances and with tests on supports, fittings and foundations.

Including design requirements for supports and foundations to be able withstand the required mechanical loadings.

Excluding Recommendations dealing with tests on conductors and insulators established respectively by Technical Committees Nos 7 and 36.?
