The work of preparing Internat

23、ional 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 theright to be represented on that committee. International organizations, governmental and non-governmental, in liai-son with

24、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

25、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

27、al Standard is for information only.DIN EN ISO 15730:2016-09 EN ISO 15730:2016 (E) 4 IntroductionElectropolishing 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 f

28、ood processing and medicalequipment.In addition to improved passivation, electropolishing provides many other benefits. Some examples are surfacestress relief, removal of surface carbon and oxides and reduction of friction. Hydrogen embrittlement of articles is notproduced during the electropolishin

29、g process, which takes minutes to perform.The quality of passivation depends on the type of stainless steel, the formulation of the electropolishing solution andthe conditions of operation. Free iron on the surface of the stainless steel is removed resulting in improved corrosionresistance. No furth

30、er chemical treatment is necessary in order to passivate the stainless steel surface. Surfacesmoothing obtained by electropolishing also improves passivation.DIN EN ISO 15730:2016-09 EN ISO 15730:2016 (E) 5 WARNING The use of this International Standard may involve hazardous materials, operations an

It is the responsibility of the user of this International Standard to establish appropriate safety andhealth practices and determine the applicability of regulatory limitations prio

Ignition of hydrogen gas canresult in dangerous explosions.1 ScopeThis International Standard specifies the i
