a) the practical running performance in specified limits of temperature, humidity, other environmental conditions, and combinations of these conditions;

b) the ability to withstand rude handling during transportation, storage, and installation.

Three Parts of IEC 60068.

• IEC 60068-1: General and guidance.
• IEC 60068-2: Tests.
• IEC 60068-3: Supporting documentation and guidance.

Now, I will introduce each of them in detail one by one.

Part 1: IEC 60068-1.

IEC 60068-1 was published in the year 2013. It experienced 12 revisions from the year 1960 to the year 1992. It is available in English and French.

IEC 60068-1 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 60068-1. This ninth edition is published in 1988, which cancels and replaces the eighth edition. The main changes with respect to the previous edition are listed below:
– the updated normative reference list.
– indication of normative and informative annexes.
– new informative Annex C, Environmental test tailoring.

Part 2: IEC 60068-2.

IEC 60068-2 is published in the year 2020. It is available in English and French.

The IEC 60068-2 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.

Let us take IEC 60068-2-5 Solar Radiation Testing as an example.

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.

Part 3: IEC 60068-3.

IEC 60068-3 is available for English and French. This testing method is available in the form of pdf. But there is a charge for downloading. therefore please click the IEC official website to download.
