FAQ

Questions engineers ask first

What is the difference between H05RR-F and H05RN-F?

In the CENELEC designation code, the first 'R' indicates EI4 ethylene-propylene rubber (EPR) core insulation on both cables. The second letter identifies the outer sheath: H05RR-F uses an ordinary-duty EM1 rubber sheath for dry or damp indoor rooms, whereas H05RN-F uses a polychloroprene (EM2) sheath for oil exposure and permanent outdoor service. In addition, harmonised H05RR-F extends up to 6 mm² (5G6), while harmonised H05RN-F covers 0.75–1.0 mm².

Why choose H05RR-F over a standard PVC cord such as H05VV-F?

Thermoplastic PVC cords stiffen rapidly below +5 °C and retain coil memory on workshop floors. H05RR-F uses cross-linked EI4 EPR insulation and vulcanised EM1 rubber sheathing that remain supple down to −25 °C in motion and resist brief contact with hot tools better than PVC.

Can H05RR-F be used in oily machine shops or permanent outdoor lighting?

No. Because the EM1 outer compound is a general-purpose natural/synthetic elastomer without chloroprene oil protection, EN 50565-2 restricts H05RR-F to dry or damp indoor rooms and only brief outdoor portable tool use. Where mineral oils, cutting emulsions or permanent UV weather exposure exist, specify H05RN-F, H07RN-F or H05BQ-F.

How are the cores identified inside H05RR-F?

All 2-core to 5-core H05RR-F cables follow the harmonised HD 308 S2 colour code: 2-core (X) uses blue and brown; 3G uses green-yellow, blue and brown; 4G uses green-yellow, brown, black and grey; and 5G uses green-yellow, blue, brown, black and grey.
