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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This third edition cancels and replaces the second edition (ISO 9717:2010), which has been technically
revised. The following changes have been made:
— the Scope has been clarified;
— the Normative references have been updated;
— the Terms and definitions have been replaced by a reference to ISO 2080;
— Clause 4 has been revised;
— the terms in Clause 5 have been revised;
— requirements for the phosphate layer have been revised;
— statements on corrosion resistance have been shifted to a new Annex A;
— Annex B on salt spray testing has been revised;
— Annex C to the properties of the phosphate layers has been revised.

Introduction
Phosphate conversion coatings are applied to ferrous metals, aluminium, zinc and their alloys (including
zinc- and zinc-alloy-plated steel, cadmium and their alloys) either as an end finish or as an intermediate
layer for other coatings. They are intended to
— impart corrosion resistance,
— improve adhesion to paints and other organic finishes,
— facilitate cold-forming operations, such as wire drawing, tube drawing and extrusion, and
— modify surface frictional properties so as to facilitate sliding.
Phosphate conversion coatings are produced by treatment with solutions, the main constituents of
which are the appropriate dihydrogen orthophosphates. These coatings are applied principally to
ferrous materials and zinc, and differ in coating mass per unit area and apparent density, depending on
— the construction material and surface condition of the components,
— previous mechanical and chemical treatment of the components, and
— processing conditions for phosphating.
All phosphate conversion coatings are more or less porous but can be sealed substantially by subsequent
sealant processes.
