High-Temperature Testing - Project Introduction: High-temperature testing is a reliability test that simulates a product's ability to withstand high temperatures during storage, assembly, and use, and it also serves as an accelerated life test.

The high-temperature testing is designed to determine the storage and operational adaptability and durability of military and civilian equipment and components under normal temperature conditions. It also confirms the performance of materials at high temperatures.

High and Low Temperature Testing Applications primarily cover electrical and electronic products, their components, and other materials. The rigor of the test depends on the temperature range and the duration of the testing.

Extreme temperatures may cause the product to overheat, affecting its safety and reliability, and potentially leading to damage.

Due to varying expansion coefficients among different materials, it results in bonding and migration between materials.

· Alters material properties

· Reduced electrical performance of components

· The flexibility or mechanical strength of elastic components decreases, shortening the product's lifespan.

· Accelerating the degradation and aging process of high polymer and insulating materials, thereby shortening the lifespan of the products.

· Elasticity of rubber and other flexible materials decreases, leading to cracking.

· Increased brittleness in metals and plastics leads to fractures or cracking.

· Methods for making materials脆, such as plastics and steel becoming prone to brittle failure at low temperatures, rubber materials increasing in hardness and decreasing in elasticity, etc. Reference standards for testing methods: GB/T 2423.1, GB/T 2423.2, IEC 60068-2-1, IEC 60068-2-2, EN 60068-2-1, EN 60068-2-2, etc.

High-Temperature Test Parameters: Test Temperature, Test Time, and Heating Rate

Performance Impact from High-Temperature Testing: Material thermal aging, cracking, discoloration, softening, melting, expansion, or functional failure, etc.
