Environmental testing - Part 2-11: Tests - Test Ka: Salt mist (IEC 60068-2-11:2021)
This part of IEC 60068 specifies a test method for assessing the corrosion resistance of
electrotechnical products components, equipment and materials in a salt mist environment. Its
objective is to verify that the comparative quality of a metallic material, with or without
corrosion protection, is maintained when exposed to salt mist.
This test method is useful for evaluating the quality and the uniformity of coatings applied to
protect metals against corrosion. It is particularly useful for detecting discontinuities, such as
pores and other defects, in certain metallic, organic, anodic oxide and conversion coatings.

L'IEC 60068-2-11:2021 spécifie une méthode d'évaluation de la résistance des composants, équipements et matériaux des produits électrotechniques à la corrosion dans un environnement de brouillard salin. Il s'agit de vérifier que la qualité comparative d'un matériau métallique, avec ou sans protection contre la corrosion, est maintenue dans un brouillard salin.
Cette méthode d'essai est utile pour évaluer la qualité et l'uniformité des revêtements appliqués afin de protéger les métaux contre la corrosion. Elle est particulièrement utile pour détecter les discontinuités (pores et autres défauts, par exemple) dans certains revêtements métalliques, organiques, d'oxyde anodique et de conversion.

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.
IEC 60068-2-11 has been prepared by IEC technical committee 104: Environmental conditions,
classification and methods of test. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 1981. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous

INTRODUCTION
The object of the test specified in this document is to compare the resistance of
electrotechnical equipment to deterioration from salt mist.
It is useful for evaluating the quality and uniformity of protective coatings.
The relationship between the deterioration provided by this test and long-term exposure of
electrotechnical equipment to salt laden atmospheres cannot be readily determined.
Consequently, the test cannot be reliably used to quantify the long-term aging of
electrotechnical equipment. However, as the test commonly accelerates deterioration from
salt mist, it does provide a useful means of comparing resistance of electrotechnical
equipment to deterioration from salt laden atmospheres.

Part 2-11: Tests – Test Ka: Salt mist
1 Scope
This part of IEC 60068 specifies a test method for assessing the corrosion resistance of
electrotechnical products components, equipment and materials in a salt mist environment. Its
objective is to verify that the comparative quality of a metallic material, with or without
corrosion protection, is maintained when exposed to salt mist.
This test method is useful for evaluating the quality and the uniformity of coatings applied to
protect metals against corrosion. It is particularly useful for detecting discontinuities, such as
pores and other defects, in certain metallic, organic, anodic oxide and conversion coatings.

WARNING – This document can involve hazardous materials, operations and equipment. This
document does not purport to address all of the safety concerns, if any, associated with its
use. It is the responsibility of the user of this document to establish appropriate safety and
health practices and determine the applicability of regulatory limitations prior to use.
For equipment and components, Test Kb (IEC 60068-2-52) is considered to provide more
realistic conditions and to provide means of assessment of individual items. If, however, for
particular circumstances, the relevant specification requires this test (Ka) to be applied to
individual specimens for qualification purposes, then the specimens should be tested as part
of the overall assembly or equipment in which they are to be used and be completed with any
protection devices (cases, covers, shields, etc.), as in practice.
NOTE 1 "Salt mist" is also called "salt spray".
NOTE 2 The test specimen(s) is typically not energized during the test.
