UL Flexible Co This Standard was published hzs 19 March The following are represented on Committee EL To maintain bzs currency, all Standards are periodically reviewed, and new editions nxs published.
Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.
Alternatively, both organizations publish an annual printed Catalogue with full details of all current Standards. For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their respective national Standards organization. We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities.
Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the back cover.
This Standard was issued in draft form for comment as DR The Standard is downloaded from www. No part of this work may be reproduced or copied in any form or by any means, electronic or mechanical, including photocopying, without the written permission of the publisher.
The nominal cross-sectional areas of the conductors specified in this Standard are identical with the values recommended in IECConductors of insulated cables. Where the equivalent cords exist in IEC Standards, the dimensions for insulation and sheath thicknesses have been adopted in this Standard. The temperature ratings and hence properties of insulation and sheath materials for these dimensionally equivalent cords, however, are quite different.
This Standard differs from the edition as follows: Thermoplastic elastomer insulated flexible cords have been deleted. Both duty rating and voltage designation have been provided for all constructions. The Tables nzd insulation and sheathing thicknesses for the various flexible cord types have been removed from the construction Clauses and consolidated into four Tables.
Superfluous wording has been deleted from the Clauses covering construction requirements. The Clauses on marking have been revised.
Cross-linked polyolefin insulation materials have been added. Compliance with this Standard does not necessarily imply suitability for end use. End applications need to be considered to ensure appropriate cord selection. 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. Purchasing guidelines are contained in Appendix A. Appendix B will facilitate the selection of cords to this Standard, which should replace the designated IEC cords.

It is right hand when the slope is in the direction of the central part of the letter Z, and left hand when the slope is in the direction of the central part of the letter S. These tests are of such a nature that after they have been made, they need not be repeated unless changes are made in the cord materials or design which might change the performance characteristics.
The duty rating is a guide to the physical suitability of the cords in various applications. In this Standard the construction clauses indicate the duty rating and voltage designation as indicated below. The mass of the insulation shall be either green or yellow, the other colour may be part of the mass or at the surface only. Cores insulated with R-S or R-S which are intended to be used as earth conductors may be durably coloured green.
For other than earth conductors and the unprotected parallel-webbed 2-core flat cords, the following colour scheme is recommended: The core sequence of the laid-up cores should be in the order specified in Clause 2. The earth core, if any, shall always be last, following the active cores, and the neutral, if any.
The electrical resistance of the screen shall not be greater than that permitted for an active conductor of the completed cord. The number of spindles and wires per spindle shall be sufficient to ensure that the filling factor is not less than 0.
For R-S and R-S insulated cords, a continuous filament glass fibre yarn. Glass fibre braid shall be impregnated with a suitable varnish. The approximate thickness of any non-metallic braid in the case of glass fibre braided cords inclusive of the varnish coatingshould be 0. Approval mark where required by a regulatory authority. Designation of voltage, e.
Designation of duty rating for multi-core sheathed cables, e. The distance between the end of one block of marking and the beginning of the next shall not exceed mm. The number of cores and the size of conductors and, in the case of R-S insulated cords, whether the conductor is tinned, silver-plated or nickel-coated. Designation of insulation and sheath or other protective covering sif any. The catalogue number, type number, name or other marking to distinguish the cord. After all burning has ceased, the surface of the sample shall be wiped clean, and the charred or affected portion shall not extend to within 50 mm of the lower edge of the clamp fitted at the top.
Application to assessment of fire hazard The test provides direct data on the likelihood of a single electric cable igniting and transmitting fire when exposed to a specified external ignition source. Fire, however, is a complex phenomenon and its behaviour, when associated with a cable run, is a function of the characteristics of the cable materials, the method of installation, and the environment in which it is used.
Consequently, no single test can give a full assessment of the fire hazard under all possible fire conditions. There must be a constant awareness of these interrelated factors and effects of important variables in using this test to assess the fire hazard in any particular situation e. Special installation precautions may have to be taken as it cannot be assumed that a bunch of cables will behave in the same way as a single cable.
AS/NZS | SAA Approvals
Individual items of this test report should not be quoted in isolation as proof of product acceptability nor applied to directly assess performance under conditions other than as envisaged by the reference specification, e.
The compatibility test shall be carried out only for flexible cords constructed with materials from different material groups see Tables in Clause 2. Suitable for installations only where further protected. Insulation thickness in accordance with Table 2.
Cores laid up with a length of lay not exceeding 10 times the pitch circle diameter, with the outer interstices filled with textile material. Textile braid of cellulosic non-melting fibre yarn. These constructions are not considered to be flame retardant. Cores of multicore cords, laid up with glass fibre yarn fillers. Glass fibre yarn braid. These constructions are not considered to be oil resistant. Insulation and sheath thicknesses in accordance with Table 2.
As the GPS sheathed cord is more prone to mechanical damage than the conventional ordinary duty cords of Clause 2. Type of insulation and protective covering if any required. The cross-sectional area of conductors, or whether tinsel conductors, as appropriate.
The number of cores. The cord construction and type, e. The colour of the cores. IEC cords are required to comply with a thermal stability test. IEC cords have no defined requirements for resistance to combustion propagation.
A block, made of aluminium according to Figure C1, with smooth, flat surfaces. Steel base plate and upright, with guide rods, according to Figure C1, so designed that the aluminium block can slide between the guide rods without impediment and that any lateral tilting is avoided. Timer; for example, stopwatch. Subsequently, the aluminium block shall be removed from the sample. These standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate.
