Purpose of IEC 60068-2-2
The objective of this standard is to determine whether a specimen can continue to operate or maintain its specified characteristics after prolonged exposure to dry heat.
Typical evaluation includes:
Heat resistance of electronic assemblies
Material dimensional stability
Plastic deformation
Seal integrity
Electrical performance verification
Mechanical property changes
Product aging assessment
The test may be performed on complete products, subassemblies, or individual components depending on the qualification requirements.
Typical Test Conditions
Although test parameters are determined by product specifications, IEC 60068-2-2 commonly includes:
| Parameter | Typical Value |
|---|---|
| Temperature Range | +40°C to +200°C |
| Exposure Time | 2 h, 16 h, 72 h or longer |
| Humidity | Dry Environment |
| Air Circulation | Forced Air |
| Temperature Uniformity | Controlled throughout chamber |
| Sample Status | Operating or Non-operating |
The exact severity level should always follow the applicable product standard or customer specification.
Test Equipment Requirements
A compliant Dry Heat Test Chamber should provide:
Accurate temperature control
Excellent temperature uniformity
Stable airflow distribution
Reliable long-duration operation
Fast recovery after door opening
Automatic safety protection
Data logging and traceability
For laboratories performing qualification testing, temperature calibration and chamber validation are equally important to ensure repeatable results.
