10、specifies the characteristics of post installation flexible self-wrapping fire protection sleeves for electrical cable and cable bundles, providing 360 fire protection to electrical harnesses. The sleeve assembly gives fire resistance protection to the internal electrical harness against fire for fi

11、ve minutes, and ensures that the electrical characteristics of cables will not be degraded. 2 Normative references The following referenced documents are indispensable for the application of this document.

17、cteristics 4.1 Requirements The sleeve shall protect the internal electrical harness against fire for five minutes, and will ensure that the electrical characteristics of cables will not be degraded. The composition of the sleeve shall be such that a uniform circular cross-section is maintained thro

18、ughout the length of the harness to be protected. The material used in the manufacture of the sleeve shall have no corrosive effects upon the harness, and shall not be susceptible to attack by mould or other micro-organisms. 4.2 Composition The multi-layer, thick wall sleeve is self-wrapping and ope

19、nable, and is of one continuous width made up of three different materials attached edge to edge. See Table 1 and Figures 1, Figures 2 and Figures 3. Where the sleeve is to be fitted to branched harnesses, the sleeve junctions may be protected by wrapping with a similar flat-sectioned multi-layer, t
