Passenger vehicle sealing strips are prone to aging due to exposure to various factors such as sunlight (ultraviolet rays), high heat (exceeding 80℃ in summer), oxygen, ozone, and humid heat. Therefore, in practical application environments and performance requirements, sealing strips have high requirements for weather resistance and resistance to light aging.

Testing for formaldehyde (VOC) in toys is of great significance for promoting toy production, processing, and export trade, as well as for addressing new technology barriers and enforcing regulations.

When purchasing thermal shock test chambers, some users choose a two-chamber model, while others opt for a three-chamber model. The price difference between the two is minimal. What factors lead users to choose the three-chamber thermal shock test chamber?

Huanyi Instrument Company has started work normally on February 24, 2026 (the eighth day of the first lunar month).

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.
