IEC/TR 62125, which is a technical report, is intended to give assistance to standard-writers of IEC Technical Committee 20, to take into account the relevant environmental aspects as far as they are specific to electric cables in normal use. It also assists them to keep in mind a clear methodology when considering these aspects and when checking possible interaction of the normative requirements with the environment. Also, these guidelines assist standard- writers to avoid too simple or too stringent requirements that might not achieve a favourable global result. This technical report, by its very nature, is not prescriptive and does not limit innovation. NOTE 1 The term ‘environment’, as used in this report, differs from the term as used in those IEC standards dealing with the impact of environmental conditions on electrotechnical products (see 3.1). NOTE 2 As regards the impact of environmental conditions on the performance of products, reference is made to IEC 60068, IEC 60721 and IEC Guide 106
