| Nosaukums | This Part 2-27 of EN 50290 gives specific requirements for halogenfree polyolefin based sheathing compounds used for halogenfree communication cables with improved characteristics in the case of fire. It is to be read in conjunction with Part 2-20 of EN 50290, the product standards EN 50288 and other applicable product standards. Improved characteristics in the case of fire are demonstrated by specific fire tests on cables for flame/fire retardant applications (e.g. single or bunched cable fire test). Additional tests to prove the characteristics in case of fire, e.g. such as smoke emission test, might also be part of the dedicated product standard or specification. This Part 2-27 of EN 50290 describes the compound types as given in Table 1 <TABLE> Compounds, described by this standard, are commonly also named HFFR-LS (halogen free, flame/fire retardant, low smoke), see also Part 2-20. |
