EMI Screen System
For applications where electromagnetic interference is of
particular concern we have classified suitable conduit
systems by means of symbols. These are related in an
ascending scale of performance from Standard EMI Screen
(products featuring a stainless steel overbraid) through to
High EMI Screen (products featuring a tinned copper
overbraid). Contact us for full details.
Fire Performance
Adaptaflex has introduced a set of symbols to help the user
specify conduit systems for installations where fire
performance is of particular concern.
Each symbol encompasses a range of properties relevant to
the high specification materials used in the construction of
the conduit.
They are in an ascending scale of
performance from Low Fire Hazard (LFH)
featuring zero halogen through to Super Low
Fire Hazard (SLFH) featuring zero nitrogen.
In addition, Inherent Low Fire Hazard
systems (ILFH) are classified as being all
metal systems.
