The performance indicators of a high and low temperature test chamber are crucial because they directly affect the reliability of test results, the breadth of application scenarios, and the effectiveness of quality assurance for products.

Previously, we discussed the changes that occur in objects during high-temperature testing. But what happens when materials are subjected to low-temperature testing in a low-temperature test chamber?

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.

When test samples are exposed to low temperatures in a thermal shock test chamber, they may suffer certain adverse effects. This is because the physical properties of the materials can change under extreme cold, potentially leading to performance degradation. So, what specific impacts can occur?

Proper protective measures are essential when operating a UV aging test chamber because it uses UV lamps, which can cause eye damage if not handled correctly. To prevent such risks, appropriate precautions must be taken.
