25、r silicone rubber (SiR) for portable earthing and short-circuiting equipment. For this type of cable no rated voltage is given as such cables are exclusively intended for earthing and short-circuiting equipment. The particular types of cable and their code designations are specified in Clause 6 of t
26、his standard. The test methods specified in this standard are given in EN 50395, EN 50396, IEC 60811 and IEC 62230. NOTE In addition to the requirements given in this standard, mechanical requirements and requirements for the marking for the complete equipment should be taken into account. These req
27、uirements can be found in IEC 61230. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments
