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 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 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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 2082 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings,
Subcommittee SC 3, Electrodeposited coatings and related finishes.
This third edition cancels and replaces the second edition (ISO 2082:1986), which has been technically
revised.

Introduction
Electrodeposits of cadmium are used to protect iron and steel from corrosion. Cadmium is anodic and
corrodes sacrificially, thus protecting ferrous basis metals even when exposed through pores or pits in the
cadmium. Electrodeposited cadmium coatings have traditionally been applied to iron or steel from alkaline
cyanide solutions, but in recent years, environmental concerns and regulations have led to increased use of
acid sulphate, neutral chloride and acid fluoborate cadmium solutions.
Because the appearance and serviceability of electroplated cadmium coatings are influenced by the surface
condition of the basis metal, agreement should be reached between the interested parties that the surface of
the basis
