Edition);
e) Add a Clause on "Specimens" (see Clause 7 of this Edition);
f) Adjust the content of "Notes" in the Clause on "Pre-conditioning" to the main text (see
Clause 9 of this Edition; Clause 5 of the 2008 Edition);
g) Add a Clause on "Arrangement of Test Specimens" (see Clause 10 of this Edition);
h) Change "Conditional test" into "Operating Conditions"; and change the content (see
Clause 11 of this Edition; Clause 6 of the 2008 Edition);
i) Add a Clause on "Test duration" (see Clause 12 of this Edition);
j) Change "Details to be given in the relevant specifications" into "Information to be given
in the relevant specifications"; and change the content (see Clause 15 of this Edition;
Clause 10 of the 2008 Edition);
k) Change the content of "Test report" (see Clause 16 of this Edition; Clause 9 of the 2008
Edition).
This Document equivalently adopted IEC 60068-2-11.2021 Environmental Testing – Part 2-11.
Tests – Test Ka. Salt Mist.
The following minimal editorial changes were made to this document.
Environmental Testing –
Part 2.Test Methods – Test Ka. Salt Mist
1 Scope
This Document 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.
