Dry Heat Test / High Temperature Testing

High Temperature Testing, commonly referred to as Dry Heat Testing, is a critical part of environmental testing used to assess the ability of products, components, or systems to withstand exposure to elevated temperatures. This form of testing is particularly important for equipment intended for use in high-temperature environments, where performance, safety, and structural integrity could be affected by heat stress.

These elevated temperatures may be the result of ambient environmental conditions (e.g., desert environments, engine compartments, or industrial facilities) or induced internally during regular operation. The purpose of high temperature testing is to simulate these harsh conditions in a controlled laboratory environment and verify that the test specimen continues to function as expected, without physical damage, performance degradation, or material failure.

The Dry Heat Test specifically involves the use of continuous, heated air—without moisture—to replicate these high-temperature conditions, and is governed by various industry standards such as IEC 60068-2-2, MIL-STD-810H (Method 501.7), and other related test protocols.

The objective of Dry Heat or High Temperature Testing is to:

• Evaluate the thermal endurance of materials and components.
• Determine the impact of long-term or intermittent exposure to elevated temperatures on product functionality.
• Identify thermal failure modes, such as warping, cracking, delamination, discoloration, or degradation of electrical performance.
• Support qualification and compliance testing for regulatory or customer-specific requirements.
• Simulate real-world environmental conditions to ensure operational reliability and safety.
