EN 50290-2-37:2016 (E)3 BS EN 50290-2-37:20161 Scope This Part 2-37 of EN 50290 gives specific requirements for Polyethylene (PE) compounds to be used for the insulation of coaxial cables. The standard includes Low Density (LD), Medium Density (MD) and High Density (HD) Polyethylen
16、e compounds. It is to be read in conjunction with EN 50290-2-20, EN 50117 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 suitabl

This data are to be provided by the compound suppli
25、er. For compounds intended for foam application the properties shall be measured on unexpanded compound or the base polymer without blowing agent. Relevant test methods, requirements and limits shall be included in any supply specification of the raw material. Specific requirements are shown (Table
26、1, Table 2 and Table 3). In the case of special applications, additional requirements could be specified. 4 Cable test requirements The anticipated performance assumes standard cable design and conventional process technology and is specified (Table 4). Using type test data the raw material supplier
27、 is expected to demonstrate compliance and warrant that the material is suitable for the specified application. In the case of special applications, additional requirements could be specified. 5 Health, safety and environmental regulations The materials are subject to Health, Safety and Environment
28、(HSE) requirements as defined in EN 50290-2-20. Any deviations or compliance failures shall be identified by the raw material supplier and necessary corrective actions to be undertaken agreed with the cable maker.
