18、4 1 Scope This European Standard 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 elect
19、rical harness against fire for five minutes, and ensures that the electrical characteristics of cables will not be degraded. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

25、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 throughout the
26、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 microorganisms. 4.2 Composition The multi-layer, thick wall sleeve is self-wrapping and openable and is
27、 of one continuous width made up of three different materials attached edge to edge. See Table 1 and Figure 1, Figure 2 and Figure 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, thick wall tape m
28、ade up of three different materials attached face to face. See Table 2 size code 00 and Figure 4.
