Most cables feature PVC insulation, some have a basic fire rating such as CL3, etc. Unfortunately, most cables give off hazardous toxic smoke during a fire, posing a very serious health risk.
LSZH cables are made from a special compound that performs as well as PVC insulation, but crucially gives off very little smoke and no halogen toxins in the event of a fire.
Many leading architects and builders along with commercial and marine designers are now specifying LSZH spec cables as standard.
Only LSZH cables meet the legislated fire specifications for boat installations.
The QED Pro LSZH Declaration of Conformity can be downloaded here:
|Each complete QED Professional cable design is fully tested to LSZH standards and reports are available on request. |
We don't just use a fire rated jacket material over an ordinary cable assembly; each complete cable design including jacket and all internal conductors has to undergo rigorous fire safety testing to the following standards:
Measurement of smoke density of cables burning
under defined conditions.
Test for vertical flame propagation for a single insulated wire or cable.
(Amendment1, 1997) test on gas evolved during combustion of electric cables.
