Environmental testing - Part 2: Tests - Test Kb: Salt mist, cyclic (sodium chloride solution) (IEC 60068-2-52:2017)

This part of IEC 60068-2 specifies the application of the cyclic salt mist test to components or
equipment designed to withstand a salt-laden atmosphere as salt can degrade the
performance of parts manufactured using metallic and/or non-metallic materials.

ENVIRONMENTAL TESTING –

Part 2-52: Tests – Test Kb: Salt mist, cyclic

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60068-2-52 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This third edition cancels and replaces the second edition published in 1996. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the entire content has been harmonized with ISO 9227 as far as possible;
b) an introduction has been added;
c) the scope has been simplified;
d) normative references have been updated;
e) the general description of the test has been changed;

f) a dry chamber has been added to the test apparatus;
g) severities have been changed to test methods;
h) test methods 7 and 8 have been added;
i) information on the test report has been added;
j) Figure 1 has been changed to Table 1;
k) a typical test apparatus example has been added in a new Annex A;
l) a description of each test method has been added in a new Annex B;
m) bibliographical references have been added.
The text of this International Standard is based on the following documents:

104/751/FDIS 104/761/RVD

Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60068 series, published under the general title Environmental
testing, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,

INTRODUCTION
The mechanism of corrosion on metallic materials in a chloride-containing atmosphere is
electrochemical, whereas the degradation effects experienced on non-metallic materials are
caused by complex chemical reactions of the salts with the materials involved. The rate at
which corrosive action takes place is dependent, to a large extent, on the supply of
oxygenated salt solution to the surface of the test specimen(s), the temperature of the test
specimen(s) and the temperature and humidity of the environment.
Apart from the corrosive effects, this cyclic salt mist test may be used to indicate deterioration
of some non-metallic materials by assimilation of salts. In the various test methods described
in this document, the period of spraying with the relevant salt solution is sufficient to wet the
test specimen(s) thoroughly. Because this wetting is repeated after intervals of storage under
humid conditions supplemented by storage under a standard atmosphere, it goes some way
to reproducing the effects of natural environments.
Furthermore, considering natural environments for corrosion on metallic materials, neutral or
acidified salt solution spray, humid, and dry conditions are also important factors as a cyclic
corrosion test. Each condition is repeated after intervals of other conditions in different
combinations to achieve corrosion on metallic materials and to get acceleration of corrosion.
The tests described in this document are accelerated compared with most expected
conditions of use. As a result, it may be difficult to establish an overall acceleration factor for
all kinds of test specimens. This also means that it is often not possible to use results gained
from these tests as a comparative guide to the long-term behaviour of different coating
systems since the corrosion stress during these tests differs significantly from the corrosion
stresses encountered during use. Nevertheless, the method described gives a means of
checking that the comparative quality of a metallic material is maintained.
