The work of preparing Internati

    8、onal Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with IS

    9、O, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Pa

    14、m This fourth edition cancels and replaces the third edition (ISO 5002:2008), of which it constitutes a minor revision.iv ISO 2013 All rights reserved INTERNATIONAL ST ANDARD ISO 5002:2013(E) Hot-rolled and cold-reduced electrolytic zinc-coated carbon steel sheet of commercial and drawing qualities

    15、1 Scope This International Standard specifies the characteristics of carbon steel sheet of commercial and drawing qualities in cut length or coil form, zinc coated by electrolytic deposition. Electrolytic zinc-coated sheet is intended for the manufacture of formed or of miscellaneous parts, and can

    16、be supplied chemically treated to render it more suitable for painting. The zinc coating is expressed in micrometres of thickness per side, for equally coated, differentially coated, or one-side-coated sheets. These sheets are generally produced with coatings, which are not intended to withstand out

    17、door exposure without chemical treatment and painting. Electrolytic zinc-coated sheet can be produced in thicknesses of 0,36 mm and thicker (normally up to 4,0 mm) and in widths of 600 mm and over in coils or cut lengths. It is recognized that materials thinner than 0,36 mm or thicker than 4,0 mm ca

    18、n be suitable for electrolytic zinc coating, and, if required, be the subject of agreement between the interested parties. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references,

    19、 only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

    21、deposition of a zinc coating on steel sheet on a zinc coating line to produce either electrolytic zinc-coated coils or electrolytic zinc-coated cut lengths 3.2 skin pass light cold rolling of hot-rolled descaled sheet or of the cold-reduced and annealed steel sheet prior to zinc coating Note 1 to en

    22、try: The purpose of the skin pass is to produce a higher degree of surface smoothness and thereby improve the surface appearance. The skin pass also temporarily minimizes the occurrence of a surface condition known as stretcher strain (Luders lines) or fluting during the fabrication of finished part

    23、s. The skin pass also controls and improves flatness. Some increase in hardness and loss of ductility will result from skin passing. 3.3 stabilized interstitial free steel extra low carbon steel in which all interstitial elements are combined with titanium and/or equivalent elements ISO 2013 All rig

The purchaser indicates on the order which

    26、method of specifying thickness is required. In the event that the purchaser does not indicate any preference, the thickness as a combination of the base metal and coating will be provided. Annex A describes the requirement for specifying the thickness as base metal alone. 4.2 Electrolytic zinc-coate

    27、d sheet less than 600 mm wide can be slit from wide sheet and will be considered as sheet. 5 Conditions of manufacture 5.1 Steelmaking The processes used in making the steel and in manufacturing electrolytic zinc-coated cold-reduced sheet and hot-rolled sheet are left to the discretion of the manufa

    28、cturer. When requested, the purchaser shall be informed of the steelmaking process being used. 5.2 Chemical composition The chemical composition (heat analysis) shall not exceed the values given in Tables 1, 2, and 3.
