FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why does H07RN-F fail LSZH fire specifications while H07ZZ-F passes?

Standard H07RN-F uses a polychloroprene (chlorinated rubber) EM2 outer sheath that releases dense black smoke and corrosive hydrochloric acid gas when burned. H07ZZ-F is built to EN 50525-3-21 using cross-linked EI8/EM8 zero-halogen compounds that pass EN 60754-2 acid gas, EN 61034-2 light transmittance (≥ 60 %) and EN 60332-3-24 Cat. C bunched flame tests.

What does 'ZZ' mean in the H07ZZ-F designation?

Under the CENELEC harmonised code, 'Z' designates a cross-linked polyolefin or elastomeric compound with low emission of corrosive gases and smoke when exposed to fire. 'ZZ' means both the core insulation (Type EI8) and the outer sheath (Type EM8) are low-smoke zero-halogen thermoset elastomers.

Where is H07ZZ-F most commonly required instead of H07RN-F?

H07ZZ-F is specified for data centre loadbank commissioning, airport terminals, underground metro stations, theatres, exhibition halls, hospitals and tunnel construction where flexible rubber mechanical handling is needed inside occupied or enclosed spaces.

What if I need a 0.6/1 kV heavy mining-grade halogen-free rubber cable?

For heavy underground mining, tunnelling and severe mechanical trailing at 0.6/1 kV where halogen-free fire performance is required, compare H07ZZ-F with our NSHXÖU-J / NSHXÖU-O cable to DIN VDE 0250-812.
