16、N 9133. 6 Identification 6.1 Sleeve model A tracer line shall be included to indicate the minimum overlap, defining the maximum admissible bundle diameter for which the sleeve can operate. To identify each product standard, coloured tracer line identification shall be included on the external edge.
17、The tracer line indicating the minimum overlap shall have the same colour as the tracer line on the external edge, according to Table 2. Tracer line materials shall be compatible with sleeve temperature range during all the service life. Table 2 Product standard Colour EN 4674-003 Blue EN 4674-004 R
18、ed or pink 6.2 Size code To identify each sleeve size, unless otherwise specified in product standard no specific tracer shall be specified. The size can be verified by the installation of the sleeve on a mandrel or bundle and the tracer line. 6.3 Inside fibres Unless otherwise specified in product
19、standard, the mono- or multi-filament fibres used to hold the group of wires together shall be of natural colour. 7 Example for designation in product standards EXAMPLE Description block SLEEVE, PROTECTION Identity block EN4674-XXX-XXX Number of the basic standard Product standard Size code (see pro
20、duct standard) Variant (if any) prEN 4674-002:2012 (E) 5 8 Packaging Electrical sleeve shall be supplied on drums or spools. The mass of a loaded drum or spool shall not exceed 13 kg. 9 Marking Each drum or spool shall have a label indicating: manufacturers name and designation; electrical sleeve de
21、signation according to Clause 7 (Identity block); batch number; date of manufacture (month, year); inspectors mark; total length and length of each piece of sleeve in metres from inside to outside. 10 Storage The following storage recommendations are intended to assist in protecting the drums with e
22、lectrical sleeve from deterioration caused by environmental conditions existing in stores. EMI protection sleeves should not be stored outside; EMI protection sleeves should not be stored closer than 2 m from a direct UV (fluorescent) light source; EMI protection sleeve delivered on drums should be
23、left packaged until required; EMI protection sleeve on drums and EMI protection sleeve that is removed from drums should be protected against fluids and dust; artificial conditions, such as high ambient temperatures, low humidity and chemical vapours, should be avoided; storage life shall be limited to eight years maximum, unless subject to re-qualification.
