25、(E) 4 1 Scope Replacement: This European Standard specifies requirements and tests for cable trunking systems (CTS) and cable ducting systems (CDS) intended for the accommodation, and where necessary for the electrically protective separation, of insulatedconductors, cables and possibly other electr
26、ical equipment in electrical and/or communication systems installations. Themaximum voltage of these installations is 1 000 V a.c. and 1 500 V d.c.These systems are intended for mounting on walls and/or ceilings. They maybe embedded, installed in a flush or semi-flush state, surface mounted or mount
27、ed away from the surface using fixing devices. This standard does not apply to conduit systems, cable tray systems,cable ladder systems, powertrack systems or equipment covered by other standards. This standard shall be used in conjunction with EN 50085-1:2005: Cable trunking systems and cable ducti
