Annex A (normative) Clashing test

Applies to flexible cables with insulation based on ethylene propylene rubber (EPR), polyvinyl chloride (PVC) or 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 this standard. The test methods specified in this standard are given in IEC 60227-2, IEC 60245-2, IEC 60811 and IEC 62230. The significant technical changes with respect to the previous edition are as follows: - extension of the scope to cover silicone rubber as an insulation material; - introduction of a new normative annex for clashing test.
