                      and specimens

Provides a test procedure for giving a standard method for determination of the ability of components, equipments or their constituent materials, known as specimens, for withstanding of accidental contact with fluids without being unacceptably affected.

IEC 60068-2-74:1999 Gives a method of test which provides a standard procedure to determine the ability of components, equipments or their constituent materials to withstand accidental contact with fluids, without being unacceptably affected. The fluids listed 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 equipments 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. It has the status of a horizontal standard in accordance with IEC Guide 104.
