Environmental testing for electric and electronic products - Part 2: Test methods - Test Xc: Fluid contaminationScopeThis Part of GB/T 2423 gives a method of test which provides a standard procedure to determine the ability of components, equipment or their constituent materials, hereinafter referred to as specimen, to withstand accidental contact with fluids, without being unacceptably affected. The fluids listed in Part are representative of those commonly encountered in operational applications. It is not intended that a specimen should be exposed to all, or even any of them. Nor is the list intended to be complete; fluids not listed and for which a test is appropriate should be included in the relevant specification. Guidance is given in annex A on the choice of test fluids, specimens and severities. These tests are not intended to demonstrate the suitability of components or equipment to perform in continuous contact with a fluid, e.g., an immersed fuel pump. Nor are they a test to demonstrate immunity from electrolytic corrosion.Normative ReferencesThe following normative documents contain provisions which, through reference in this text, constitute provisions of this part of GB/T 2423.
