Moreover, IEC is summarized on the basis of authoritative international engineering experience and judgment. It is available in English and French.

It is primarily formulated by the IEC Technical Committee 50 to test the two kinds of properties of samples:. IEC was published in the year It experienced 12 revisions from the year to the year IEC is a collection of methods for environmental testing and stipulates various atmospheric conditions for measurements and or other activities.

This standard finds usage in assessing the ability of specimens to perform under anticipated conditions during transportation, storage, and handling. The tested samples of this standard are mainly electrotechnical products. But it is not confined to these products and may play a vital role in other fields. The following chart is the 12 revisions of IEC This ninth edition is published in , which cancels and replaces the eighth edition.

The main changes with respect to the previous edition are listed below: пїЅ the updated normative reference list. This testing method is available in the form of pdf. But there is a charge for downloading. The IEC is a collection of more than 60 standards. These standards are applicable to a climatic category, such as vibration, shock, change of temperature, dry heat, salt mist, dust and sand, mold, and the combination of them.

I will not introduce them one by one. And you can have a rough understanding of each standard from its name. From its name, you can infer that this method evaluates the expected effects of solar radiation on products. It illustrates ways of testing equipment or components under simulated solar radiation and water spray environments. IEC is available for English and French.

To determine the suitability of components, equipment or other articles for use and storage under conditions of high humidity when combined with cyclic temperature changes and, in general, pro ducing condensation on the surface of the specimen. General description This test comprises one or more temperature cycles in which the relative humidity is maintained at a high level.

Two variants of the cycle are given which are identical except for the temperature fall period during this part of the cycle, variant 2 allows wider tolerances of relative humidity and the rate of temperature fall The test severity is determined by the upper temperature of the cycle and the number of cycles see Clause 4.

Test profiles illustrating the procedure are shown in Figures 1, 2a, 2b and 3, pages 14, 15, 16 and Testing chamber The chamber shall be so constructed that the conditions given hereafter may be obtained; 3. The air in the chamber should therefore be continuously stirred at a rate necessary to maintain the specified conditions of temperature and humidity.

Initial measurements The specimens shall be visually inspected and electrically and mechanically checked, as required by the relevant specification. The specimens shall be introduced into the chamber either in the unpacked, switched-off, ready-for-use state, or as otherwise specified in the relevant specification.
