EN IEC 60068-2-2 Basic Environmental Test Procedures for Electronic Components and Electronic Equipment - Part 2: Tests - Dry heat

EUROLAB laboratory provides testing and compliance services within the scope of EN IEC 61326-2 standard. This standard covers dry heat tests applicable to both radiant and radiant specimens. For non-heat-dissipating samples, Test Bb and Bd essentially do not deviate from the previous issues.

The purpose of dry heat testing is limited to determining the ability of components, equipment or other objects to be used, transported or stored at high temperature.

These dry heat tests do not provide the ability of samples to withstand or function during the temperature changes to be evaluated. In this case, it will be necessary to use IEC 60068-2-14 Test N: Temperature variation.

Dry heat tests are subdivided as follows:

Dry heat test for non-heat-emitting samples

• With gradual temperature change, Bb,

Dry heat tests for heat dissipating samples

• With gradual temperature change, Bd,
• Power is supplied to the sample by gradual temperature change, Be,

The procedures given in this standard are normally intended for samples that achieve temperature stability during the performance of the test procedure.

Low Air Velocity in the Work Area, the rate of air conditioning airflow within a work area that is low enough to maintain conditions but not decrease by more than 5K by the effect of temperature at any point on the test sample. air circulation (not more than 0,5 m/s if possible)

High Air Velocity in the Work Area is the rate of air conditioning airflow within a work area that, to maintain conditions, also reduces the temperature at any point on the test specimen by more than 5K by the action of air circulation.
