Note 1: A combustible gas is a gas or any fuel that is in a gaseous state at a temperature of 15°C at a pressure of 1 bar.

This European Standard specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessories and their joints for the construction of drains and sewers outside buildings: - operating without pressure, or with positive or negative pressure; - installed below or above ground; - for conveyance of surface water, domestic waste water and certain types of industrial effluents, either in separate systems or in mixed systems.
