3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 4674-001 apply.
4 Required characteristics
4.1 Composition
This product is manufactured from PPS (polyphenylene sulphide) monofilaments and nickel-plated copper wire, with or without an internal protective tape.
4.2 Dimensions and mass of the sleeve
See Figures 1 and 2, Tables 1 and 2.
4.3 Colour, materials and tracer line identification
4.3.1 Colour, tracer line and sleeve identification
See EN 4674-001.
4.3.2 Internal mechanical protection tape
The sleeve can be delivered with an internal mechanical protection tape according to ASTM D4894 Type IV,Grade 2 for electrical insulation between the cables and the metallic flat braid; see Table 3.
4.3.3 Size identification
To identify each sleeve size, 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.
