This European Standard specifies the requirements against ingress of water and tests for flexible non-flame propagating liquid tight sheathing systems for the protection and management of insulated conductors and/or cables in electrical installations or in communication systems up to 1 000 V a.c. and/or 1 500 V d.c. This standard applies to metallic, non-metallic and composite liquid tight sheathing systems including threaded fittings which terminate the system This European Standard does not apply to conduit systems for electrical installations which come within the scope of EN 50086 series as well as EN 61386 series. Liquid tight sheathing systems do not provide mechanical protection to insulated conductors and/or cables. They are not for use within the construction of buildings as a component of a fixed wiring system. NOTE Earthing conductors may or may not be insulated.
