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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings,
Subcommittee SC 8, Chemical conversion coatings.
This fourth edition cancels and replaces the third edition (ISO 9717:2017), which has been technically
revised.
The main changes are as follows:
— the Introduction has been clarified (1 bracket shifted);
— 5.1 Table 1 formatted and for ZnpH second line added to describe types of Znph; new Table 1 copied
on Table C.1
— 5.2 and ff.: all terms are uniformed from “phosphate coating” or “conversion coating” to “phosphate
conversion coating” (when applicable);
— 5.2 and ff.: “after-treatment” was changed to “post treatment”; other definitions and spelling
changed according to ISO 2080;
— 6.3 Table 2: definition of T1 recharged, second sentence deleted (this is content of T2);
— 6.3: last sentence updated to describe impact of neutral salt spray test;
— 6.4: revision of 6.4, thickness measurement replaced by area related mass;
— Annex B: last sentence deleted: Table B.1 updated;
— Annex B: Table B.1 and B.3 headlines updated;
— Annex B: Table B.4 headline updated;
— Annex C: the element nickel has been added to C.1, C.2.3, C.2.5 and C.4; ICP was added as method to
C.2.3; XRF was added as method to C.3.

Introduction
Phosphate conversion coatings are produced by treating substrates with appropriate solutions. The
main constituents of these solutions are the appropriate dihydrogen orthophosphates. These coatings
differ in coating mass per unit area and apparent density, depending on.
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 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 porous but can be sealed substantially by subsequent sealant
processes.
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed
that compliance with this document may involve the use of a patent.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO that he/she is willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In
this respect, the statement of the holder of this patent right is registered with ISO. Information may be
obtained from the patent database available at www.iso.org/patents.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those in the patent database. ISO shall not be held responsible for identifying
any or all such patent rights.
