Moisture sensitivity level (MSL) is a rating that shows a device's susceptibility to damage due to absorbed moisture when subjected to reflow soldering as defined in J-STD-020.
IEC 60068 is an international standard for the environmental testing of electrotechnical products that is published by the International Electrotechnical Commission (IEC).. IEC 60068 is a collection of methods [1] for environmental testing of electronic equipment and products to assess their ability to perform under environmental conditions including extreme cold and dry heat.
The previous United States Military Specification Mil-I-8835A [permanent dead link ] was the governing specification for a humidity indicator card. The humidity indicator card is also specified for use in J-STD-033, which is the standard for handling, packing, shipping and use of moisture/reflow sensitive surface-mount devices.
Example of a temperature/humidity chamber Example of a Walk-In Environmental Chamber used for automobile reliability testing in various simulated environment. An environmental chamber, also called a climatic chamber or climate chamber, is an enclosure used to test the effects of specified environmental conditions on biological items, industrial products, materials, and electronic devices and ...
Mixed flowing gas (MFG) is a type of laboratory environmental testing for products, particularly electronics, to evaluate resistance to corrosion due to gases in the atmosphere. Mixed Flowing Gas (MFG) test is a laboratory test in which the temperature (°C), relative humidity (%RH), concentration of gaseous pollutants (in parts per billion ...
A hygrometer is an instrument which measures the humidity of air or some other gas, that is, how much water vapor it contains. [1] Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.

Humidity These tests under humidity check the effects of high concentrations of humidity and the articles ability to withstand moisture effects such as corrosion. Typically moisture sensitive devices have issues with this test and require conformal coat or other types of protection.
