Specifies construction, dimensions and tests for flexible cords insulated with thermoplastic or crosslinked PVC, thermoplastic or crosslinked elastomers, glass fibre or thermoplastic fluoropolymers for working voltages up to and including 250/250 volt, 250/440 V or 0.6/1 kV.

This Standard specifies construction, dimensions and tests for flexible cords insulated with thermoplastic or crosslinked PVC, thermoplastic or crosslinked elastomers, glass fibre or thermoplastic fluoropolymers which, dependent on cord type, are designed for working voltages up to and including 250/250 V, 250/440 V or 0.6/1 kV. Compliance with this Standard does not necessarily imply suitability for end use. End applications shall be considered to ensure appropriate cord selection.NOTES:1 This Standard is intended to apply only to flexible cords of the types and sizes which are included. It is not intended, however, that other types or sizes of flexible cord should be precluded from use, and regulatory authorities will consider the issue of a Certificate of Suitability for connection to the supply mains under the non-declared scheme for other types and sizes as they are developed. Any application for such certification should be accompanied by a description of the flexible cord.2 Purchasing guidelines are contained in Appendix A.3 AS/NZS 3350 series of appliance Standards is being issued, nominating flexible cords to IEC 227 and IEC 245. Appendix D will facilitate the selection of cords to AS/NZS 3191, which should replace the designated IEC cords.
