16、 specific requirements for Polyethylene (PE) compounds to be used for multi element metallic data cables for indoor application. The standard includes Low Density (LD), Medium Density (MD) and High Density (HD) Polyethylene compounds. It is to be read in conjunction with EN 50290-2-20, the product s
17、tandard EN 50288 and other applicable product standards. Using compound and type test data as outlined in this standard, the compound supplier will have sufficient data to demonstrate compliance and warrant that the material is suitable for the specified application. 2 Normative references The follo
