This Part 2-34 of EN 50290 gives specific requirements for polyethylene compounds, as given in Table 1, to be used for low shrinkage sheathing elements of fibre optic cables. All the compounds in this standard are suitable for sheathing cables to be used in outside plant having a maximum operating temperature of 70 °C. In addition, EN 50290-2-34 will give guidance in the selection of polyethylenes for other applications where low sheath retraction is necessary. It is to be read in conjunction with EN 50290-2-20, the product standard EN 60794-3 and other applicable product standards.
Using raw material and type test data as outlined in this standard, the raw material supplier will have sufficient data to demonstrate compliance and warrant that the material is suitable for the specified application.
