This International Standard provides general guidance for the safe use of electric cables with a rated voltage not exceeding 450/750 V. It is applicable to those cables that are specified in IEC 60227 and IEC 60245. The guidance given in this standard can also be applicable to low-voltage cables of a similar type to those specified in IEC 60227 and IEC 60245 but not specifically mentioned in those standards. In such cases, it is advisable to seek additional advice from the cable manufacturer. NOTE Whilst this International Standard, which offers guidelines to the user, is a voluntary standard, those who choose to use it, or who claim conformance to it, must follow the advice contained therein, e.g. with regard to certain bending radii or certain clip spacings, etc. Notwithstanding this, national laws and regulations (especially those relating to selection and installation of cables via IEC 60364), will always take priority.
