1 Terminology 1.1 General surface corrosion Uniform removal of material from the entire material-aggressive medium contact surface. This is a very common type of corrosion. Common types are sheet corrosion and surface corrosion. 1.2 Pitting corrosion (pore corrosion) The erosion of a limited localised area by a corrosive medium which penetrates into the material to…

High and low temperature testing finds out how well products adapt to extreme temperatures in storage, transport, and use. The severity of the test depends on the high or low temperature and the duration of exposure. All products are stored, preserved, or work in certain temperature environments. Some environments have constantly changing temperatures, sometimes high…

UV weathering testing uses an ultraviolet light source to simulate sunlight. It irradiates a sample to assess how quickly it ages under UV light. This test method simulates prolonged UV exposure in real use. It assesses the material’s weathering performance and lifespan. Scope of application The UV weathering test applies to a wide range of…

Warm tips about sending samples before UV aging test: 1. UV aging tests must provide comparison samples. If you can cut the sample, you do not need to provide comparison samples. 2. The standard sample size: length 50-150 mm, width 50-75 mm, thickness <10 mm. According to the standard, test 3 samples. It’s best to…

A constant temperature and humidity box has precise controls. It tests high and low temperatures and different humidity levels. It’s suitable for electronics, food, plastics, auto parts, lamps, chemicals, building materials, and clothing. It detects changes in temperature and humidity during tests. Proper use and upkeep of the humidity box can greatly extend its life….

Background of the IEC 61215 standard and differences between the two versions Background of IEC 61215 IEC 61215 is an IEC test method. It is for ‘Crystalline silicon ground-mounted PV modules – Design confirmation and type approval’. The standard is now widely used by the solar industry to test materials or products. Differences between IEC…

The salt spray test chamber is also known as a salt spray tester. Its full name is salt water spray tester. It is mainly used to test the corrosion resistance of the sample. It is now widely used in aerospace and car electronics. And it is also used in electrical engineering, phone tech, plastics, and…

1. First of all, we have to figure out what is the environmental test? We test cars to make the weathering stress of the environment worse. This ages and breaks car parts. It shows us how well the parts can handle these stresses (like temperature, humidity, light, rain, impact, salt spray, etc.). Cars face this…

When selecting a hot and humid box, pay attention to its performance parameters. These include the temperature range, uniformity, volatility, warming speed, and cooling rate. They also include other factors. They determine if the box can meet the test’s conditions. Uniformity is important in these factors. We need to pay special attention to it. We…

 Nowadays, the requirements for product quality are becoming increasingly stringent in various industries. Environmental test chambers are important tools. They ensure product performance and reliability. This fact is clear. It applies to aerospace, military research, weapons, and equipment. It also applies to 5G semiconductors, and the electrical and electronic industries. They all need to do…
