This part of ISO 4067 establishes conventional basic graphical symbols for conduits, pipes and ditches including fabricated parts and equipment, for use on drawings and diagrams for supply water and drainage systems in the ground. For more detailed representation, these basic symbols may be combined with designations, specified in a system of more detailed symbols, on the drawing, or describing separately. The symbols are shown and used primarily on plans, but they can in applicable cases also be used on sections, cuts and elevations.
