Communication cables - Part 2-27: Common design rules and construction - Halogen free polyolefin based sheathing compounds for cables having improved flame and fire properties (HFFR)

This document gives specific requirements for halogen free polyolefin based sheathing compounds used for halogen free communication cables with improved characteristics in the case of fire. Compounds, described by this document, are commonly also named HFFR or HFFR-LS (halogen free, flame/fire retardant, low smoke), see also EN 50290 2 20. It is expected to be read in conjunction with EN 50290 2 20, the product standards EN 50288 series, EN 60794 series 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 document describes the compound types as given in Table 1.

Communication cables - Part 2-20: Common design rules and construction - General
SIST EN 50290-2-20:2016

EN 50290-2-NN contains, in its various parts, the requirements for polymeric insulating, sheathing and covering materials that are used for metallic and optical fibre cables (Table 1). The materials to be used for EN standardised communication cables are not, and will not be, restricted only to those defined (Table 1). New materials for cables will be described in further parts of the series. The current structure of the EN 50290-2-NN series is outlined in Annex A. Furthermore, the use of materials described in the EN 50290-2-NN series for other cable applications outside those defined (Table 1) is not prohibited, but it is strongly recommended that expert advice be taken before such use, or before any proposal for incorporation into another standard.

SIST EN 50290-2-29:2016

This Part 2-29 of EN 50290 gives specific requirements for Crosslinked Polyethylene (XLPE) compounds to be used for the insulation of instrumentation, control and field bus cables. There are several routes used for manufacture of XLPE insulated cables and as a consequence a number of different types of polyethylene compound may be specified. The compounds required for the different manufacturing processes are described (Table 1). The unstabilised materials require antioxidant to be added during the cable extrusion process.

It is to be read in conjunction with EN 50290-2-20, EN 50117 and other applicable product standards. Grades PP-S1 and PP-F1 correspond to materials specified in the previous version 50290 2-25. These relatively soft Polypropylene compounds have good low temperature properties and are highly stabilised. Grades PP-S2 and PP-F2 exhibit properties more typical of Polypropylene and are designed for general Coax applications where high crush resistance and superior dielectric properties are needed. Using raw material and type test data as outlined in this standard, the raw material supplier will have sufficient data to demonstrate compliance and warrant that the material is suitable for the specified application.
