Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical com-
mittees. 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 liai-
son with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15730 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic
coatings, Subcommittee SC 8, Chemical conversion coatings.
Annex A of this International Standard is for information only.

Introduction
Electropolishing removes a small but finite amount of metal from the surface that, in addition to smoothing and bright-
ening, produces a hygienically clean surface desirable for use by manufacturers of food processing and medical
equipment.
In addition to improved passivation, electropolishing provides many other benefits. Some examples are surface
stress relief, removal of surface carbon and oxides and reduction of friction. Hydrogen embrittlement of articles is not
produced during the electropolishing process, which takes minutes to perform.
The quality of passivation depends on the type of stainless steel, the formulation of the electropolishing solution and
the conditions of operation. Free iron on the surface of the stainless steel is removed resulting in improved corrosion
resistance. No further chemical treatment is necessary in order to passivate the stainless steel surface. Surface
smoothing obtained by electropolishing also improves passivation.

INTERNATIONAL STANDARD ISO 15730:2000(E)
Metallic and other inorganic coatings — Electropolishing as a
means of smoothing and passivating stainless steel
WARNING — The use of this International Standard may involve hazardous materials, operations and equip-
ment. This International Standard does not purport to address all the safety problems associated with its
use. It is the responsibility of the user of this International Standard to establish appropriate safety and
health practices and determine the applicability of regulatory limitations prior to use.
Large quantities of hydrogen and oxygen gases are evolved at the electrodes during the electropolishing
process. Proper ventilation procedures should be used to ensure their removal. Ignition of hydrogen gas can
result in dangerous explosions.
1 Scope
This International Standard specifies the information to be supplied by the purchaser to the finisher, requirements
and test methods for electropolishing as a means of smoothing and passivating stainless steel alloys in the S2XXXX,
S3XXXX and S4XXXX series, and the precipitation hardened alloys (see ISO/TR 15510 for information on composi-
tion).
