Temperature and Humidity Test

Temperature and humidity tests are performed to determine how components, subsystems and complete systems will behave in harsh environments with high temperatures and high or varying relative humidity. In general, high changes occur in temperature and humidity. However, other environmental factors such as sand, dust, corrosion and vibration are also taken into account.

Temperature and humidity tests examine failures caused by parameter shifts, mechanical failures, optical failures (fogging), waterproofing failures or the effects of climate changes on electronic components. These tests are a critical component of a complete qualification program. Combined testing of temperature and humidity extends beyond electronic components to complete systems and finished products. For example, copiers, computers, automobiles and satellites require temperature and humidity testing.

Today, it is not enough to just design and manufacture a product. It is necessary to ensure that these products will withstand all the environmental stresses they will be subjected to after operating in the real world. Two of the biggest environmental factors that determine whether products will perform as expected are temperature and humidity.

Temperature test and humidity test work together. These two environmental forces are inevitable in the world. But in the terrestrial environment, every product manufactured, from military munitions to electronic components, is exposed to a range of temperature and humidity conditions. Some of these ranges may be excessive.

Environmental changes such as temperature and humidity strongly affect the performance of the manufactured product. Temperature and humidity testing takes all these interactions into account, and the testing process is performed to help improve the long-term durability and service life of products.

Temperature and humidity testing is actually an umbrella concept. This concept is an engineering and manufacturing generalization for a range of environmental stress tests such as high temperature low temperature testing, moisture resistance testing or temperature cycling testing.

The basic principle of temperature and humidity testing is to expose products to high environmental stresses and cause failure. There is a wide range of forces applied during temperature and humidity tests, and they depend on the particular product and its intended use. The materials in question are placed in controlled environmental test chambers, and then temperature, humidity and other forces are artificially adjusted. These high and low parameter shifts can cause mechanical deterioration of products, allowing fog or condensation, water ingress, and deterioration of structural materials.

Manufacturers consider temperature and humidity testing a high priority in their quality control programs for several reasons. Properly executed environmental testing brings products realistically to the outer limits of any natural or artificial conditions they will encounter. For example, electronic assemblies and components are the best examples for temperature and humidity testing. Manufacturers prefer parts failing in a test room to failing during an operational application where downtime and repairs can be very costly.

In short, temperature is the most common crop stress found in environmental fluctuations. Temperature changes cause products to expand or contract. Rates vary depending on the type of material being tested. Plastics react differently than metals, and temperature test parameters are always adjusted to the materials.

Humidity is the second important environmental stress factor affecting the products produced. Moisture fluctuations also cause expansion and contraction, but in general how humidity affects the inner workings of products is important. Moisture penetration or leaching is a major contributor to oxidation and corrosion. Moisture resistance is an important performance factor for electrical or computerized systems.
