24、 laminated sheets based on silicone resins 1 Scope This part of IEC 60893 gives the requirements for industrial rigid laminated sheets for electrical purposes based on silicone resins and different reinforcements. Applications and distinguishing properties are given in Table 1. Materials which confo
