BS EN 50290-2-36:2016EN 50290-2-36:2016 (E) 4 1 Scope This Part 2-36 of EN 50290 gives specific requirements for
15、 crosslinked Silicone rubber compound (SiR) to be used for the insulation of fire resistant cables. It is essential to read this European Standard in conjunction with Part 2-20 of EN 50290 and other applicable product standards. Using raw material and type test data as outlined in this standard, the
16、 raw material supplier will have sufficient data to demonstrate compliance and warrant that the material is suitable for the specified application. This part 2-36 of EN 50290 describes the compound type as given in Table 1. Table 1 Crosslinked SiR insulation compound Type Maximum operating temperatu

This data shall describe the general performance of Silicone rubber insulation compounds. The
23、 data shall be provided by the compound supplier and therefore can be included in any supply specification of the raw material. Test methods, relevant requirements and limits are shown in Table 2.

24、N 50290-2-36:2016 (E) 5 4 Cable test requirements The anticipated performance assumes standard cable design and conventional process technology and is specified in Table 3. In case of specific applications, additional requirements could be specified. Relevant test methods and requirements, especiall
25、y referring to any cable fire performance, shall be included in the detailed specification of the cable. 5 Health, Safety and Environmental (HSE) Regulations The materials are subject to Health, Safety and Environmental (HSE) requirements as defined in EN 50290-2-20. Any deviations or compliance fai
26、lures must be identified by the raw material supplier and necessary corrective actions to be undertaken agreed with the cable maker.
