Short answer: certification requirements should be confirmed by product category, project country, applicable standard, buyer inspection rule and document language.
| Cable accessories | Common references include IEC 60502-4, IEC 60840 and utility specifications for MV and HV cable systems. |
|---|---|
| Cable lugs | Common references include IEC 61238-1, conductor material rules and project crimping requirements. |
| Surge arresters | Common references include IEC 60099-4, rated voltage, MCOV and discharge current test requirements. |
| Grounding materials | Common references include IEC 62561, grounding design rules and corrosion requirements. |
Do not assume one certificate applies to every model. Certification and test report needs should be checked by product type and rating.
