PVC–U material data
Marshall-Tufflex cable management
products are manufactured in Extra
Super High Impact PVC-U grade
material, capable of withstanding the
most hazardous conditions on site and
which exceeds the most stringent
requirements of the British Standards.
Characteristics
Chemical resistance
The material is virtually unaffected by
solutions of inorganic acids, alkalis and
salts and is resistant to many organic
chemicals. It may be softened by some
organic materials such as ketones and
aromatic compounds. It will not
corrode. See Chemical Resistance table
above for further details.
Fire resistance
The material used in Marshall-Tufflex
conduit and trunking are self-
extinguishing and comply with the
requirements of BS 476 Parts 6 and 7
and BS 4678. Non-flame propagating
to BS EN 50085 and BS EN 50086.
(See Characteristics table above)
Thermal properties
Marshall-Tufflex conduit and trunking is
designed to accommodate variations
of ambient temperature equating to
5.25mm/3m for a temperature
riseof 25°C.
Operating temperatures: -5°C to +60°C.
Thermal conductivity: 0.19 w/m/°C.
Impact resistance
High impact resistance. The material is
formulated to comply with the -5°C
clause of BS 4678 Part 4 (1982) Cable
Trunking Standard and the -5°C Heavy
Gauge Requirements of BS EN 61386-1.
Standards
Trunking systems are manufactured
to comply with the requirements of
BS 4678 Part 4 (1982) where applicable.
Conduit systems comply with the
requirements of BS EN 50086
and BS 4607.
