GB/T 2423.17-2024 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.

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: The test specimen(s) is typically not energized during the test.
