Precision Testing for Reliability, Durability, and IEC Compliance
Redmark Industry offers advanced Temperature and Humidity Cycling Test Chambers by LIB, specifically engineered for the rigorous testing of photovoltaic (PV) modules. These chambers ensure compliance with IEC 61215, IEC 61646, and other international standards, simulating a wide range of environmental conditions to evaluate thermal fatigue, moisture ingress, and long-term durability.
Our chambers are ideal for R&D labs, manufacturing quality control, and certification testing, providing reliable performance data under accelerated life-cycle conditions.
Thermal Cycling Test
Simulates repeated temperature fluctuations between +85°C and -40°C to evaluate the mechanical and thermal stress on PV modules.
Maximum temperature change rate: 100°C/hour
Humidity Freeze Cycle
Performs alternating cycles of high humidity at 85°C / 85% RH and freezing at -40°C to replicate real-world environmental challenges, testing for delamination and moisture effects.
Damp Heat Test
Conducts long-term exposure at 85°C and 85% RH for up to 1000 hours to assess the module’s resistance to moisture ingress and insulation degradation.
