Primary Tests Performed

1. Steady-State Temperature & Humidity Testing

Testing products under constant warm and humid conditions to evaluate long-term resistance to moisture:

• Damp Heat (85°C / 85% RH): Standard accelerated aging test for electronics, printed circuit boards (PCBs), adhesives, coatings, and sensors. It exposes potential issues like delamination, silver migration, trace corrosion, and insulation resistance drop.

• Controlled Storage & Shelf-Life Simulation: Simulating warm, humid storage environments (e.g., +30°C to +50°C with high RH) for medical devices, pharmaceuticals, packaging materials, and sensitive consumer goods.

• Hygral Expansion & Swelling: Evaluating how plastics, composites, paper/cardboard packaging, and elastomers absorb moisture and deform or lose structural integrity.

2. Condensation & Dewing Tests

By cycling relative humidity and moderate temperatures (e.g., ramping between +20°C and +60°C with high moisture):

• Moisture Ingress & Fogging: Testing sealed electronic enclosures (IP-rated housings), automotive lamp assemblies, and optical sensors to ensure moisture does not leak inside or cause internal lens fogging.

• Corrosion & Rust Susceptibility: Accelerating surface oxidation on raw metals, platings, and electrical contacts.

3. Mild Thermal & Environmental Cycling

Because it reaches +90°C, it supports moderate heat-exposure profiles:

• Operating Temperature Limit Testing: Verifying that electronics, power supplies, and battery-powered devices run reliably at their maximum rated commercial temperatures (e.g., +50°C to +70°C).

• Diurnal Environmental Cycling: Simulating day-to-night temperature and humidity shifts typical of warm, tropical, or summer climates.

Typical Standards Supported

This operating envelope directly targets common commercial and industrial compliance standards, including:

• IEC 60068-2-30 / IEC 60068-2-78: Damp heat, steady-state, and cyclic humidity testing.

• JEDEC JESD22-A101: Steady-state temperature humidity bias life test (typically 85°C / 85% RH).

• ASTM & ISO Packaging Standards: Environmental conditioning of shipping containers, paperboard, and barrier materials prior to transit testing.
