(c)An adhesion of coating test has been included.(d)The coating mass requirements have been aligned with the requirements ofAS/NZS 4534 Class W10.(e)The electrical resistance requirements have been based on a resistivity of 0.17 mW.m to align with AS 3607.(f)Appendix B has been deleted.The term informative has been used in this Standard to define the application of the appendix to which it applies. An informative appendix is only for information and guidance.CONTENTSPage1SCOPE . 42REFERENCED DOCUMENTS . 43JOINTS . 44DIAMETER TOLERANCES . 45TENSILE TEST . 56TORSION TEST . 67COATING MASS . 68ELECTRICAL RESISTANCE . 79ADHESION OF COATING . 810PACKING . 811MARKING. 812ROUNDING OF TEST RESULT NUMBERS . 8APPENDIX A PURCHASING GUIDELINES . 9STANDARDS AUSTRALIA/STANDARDS NEW ZEALANDAustralian/New Zealand StandardGalvanized mild steel wire for armouring of cables1 SCOPEThis Standard specifies requirements for cold-drawn mild steel wire of round cross-section, galvanized (zinc-coated) for the armouring of electric and telecommunication cables.NOTE: Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A.2 REFERENCED DOCUMENTSThe following documents are referred to in this Standard: AS1391Methods for tensile testing of metals2505Methods for bend and related testing of metals2505.5Part 5:Torsion and wrapping tests on wire2706Numerical valuesRounding and interpretation of limiting valuesAS/NZS4534Zinc and zinc/aluminium-alloy coatings on steel wireIEC60468Method of measurement of resistivity of metallic materials3 JOINTSThe wire, as delivered, shall contain no joints other than welds.Joints shall be made with the ends essentially in line and burrs removed.4 DIAMETER TOLERANCESDiameter shall be determined by taking two measurements at right angles to each other at three places along a length not less than 250 mm. The average of these six measurements shall be taken as the diameter.The diameter tolerances shall be in accordance with Table 1.COPYRIGHTTABLE 1NOMINAL
