In the testing process for formaldehyde VOCs in Korean automotive standards, it is necessary to sample the gas. Below, we will learn about the relevant sampling methods.

Many people search online for instructions on how to use a VOC emission environmental testing chamber, but the results are often incomplete. Below, the manufacturer will guide you through the testing procedures for a VOC emission environmental testing chamber.

To investigate the effects of rapid temperature changes on integrated circuits, we conducted temperature cycling tests using a temperature cycling test chamber. The main test contents are as follows.

The main effects of sand and dust on the test specimen are abrasion and erosion, such as jamming, blockage, reduced heat conduction or dissipation, and electrostatic effects leading to malfunctions like jamming, increased wear, and electrical overheating. However, there are many influencing factors in sand and dust tests, which we will explore below.

Low-pressure environments can significantly impact the performance, reliability, and lifespan of signal control products. The following example of a low-pressure test on a rail transit signal electronic device illustrates the important role of low-pressure testing in product reliability assessment.

The air purifier CADR test chamber is used to test the natural decay of particulate matter. Let's see how to use the HYQW-30G model CADR test chamber to conduct particulate matter decay tests.

When driving on wet roads in winter, splashes of cold water (ice water) onto high-temperature automotive systems or components can cause thermal shock. Therefore, automotive parts need to undergo ice water shock resistance testing using a cold water thermal shock immersion tester to assess their durability in extreme environments.

Automotive weatherstripping is a widely used rubber component in automobiles. During use or storage, it is susceptible to adverse environmental factors, especially ultraviolet radiation from sunlight, which can cause surface cracking, blooming, chalking, and color changes. To investigate the changes caused by sunlight, we designed the following test scheme for reference.

In the home building materials industry, environmental protection and health have become the core lifeline of products. Among them, formaldehyde emission is a key indicator for measuring the safety of products such as boards, flooring, and furniture.

Among numerous vibration testing devices, electromagnetic vibration tables have become the mainstream choice for vibration testing in the medical industry due to their core advantages such as precise vibration control and wide applicability. This article will delve into the core benefits of vibration testing for medical products and reveal the key reasons why electromagnetic vibration tables have become the preferred equipment.
