3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 6049-001 and the following apply

3.1

after ageing

the ageing is to be understood as the effect of environmental test(s) listed in section 5 on the product performance at the end of a qualification test group

3.2

overlap angle

sleeve overlap angle for maximum wire bundle diameter

4 Required characteristics

4.1 Composition

A textile and metal openable, self-wrappable sleeving made of two layers:

 External layer: a woven blend of textured meta-aramid continuous yarn and polyphenylene sulfide (PPS) monofilament A specific feature avoids excessive fraying of the sleeving after cold cutting

 Internal layer: a metallic flat braid made of nickel copper strands as per ASTM B355 Class 27, with an option of adhesive polytetrafluoroethylene (PTFE) tape as per ASTM D1000
