1 Scope

This section sets out the basic principles of environmental aspects into duct systems and cable management slot tube.

This section applies to new or improved product design.

This section applies Conduit systems for cable management including metals, non-metallic and composite conduit systems, including those systems screw termination Inlet conduit lines and non-threaded. Cable management system includes a conductor groove tube, cable or cord electrical devices and/or other electrical equipment Preparation of ad hoc, and where necessary, they are spaced cable ducts and cable tray systems.

The purpose of this section is to the product design stage to control its impact on the environment.
