Temperature is the most fundamental—and most brutal—physical parameter influencing the reliability of materials, components and complete systems. GB/T 2423.1, GB/T 2423.2, GJB 150.3A, GJB 150.4A, DO-160 Section 4/5, IEC 60068-2-1/-2 and MIL-STD-810H all quantify requirements for temperature slew rate, dwell time, heat load and measurement uncertainty.

UV aging test chambers are designed to simulate three environmental conditions to evaluate the performance parameters of objects under ultraviolet (UV) radiation and other factors.

Previously, we discussed several factors that affect the test results of high and low temperature alternating test chambers. One critical factor is the sealing performance of the equipment, as poor sealing can lead to the following issues
