  Salt spray corrosion test is to put brake discs, fasteners, electroplated ornaments and other auto parts into the "artificial salt spray room", and spray salt spray for 48h,96h or even 1000h continuously, to see whether they will rust, bubble or fall off the coating. Simply put, it is to help you "condense" the harsh environment of the seaside and snow melting salt into the laboratory in advance, so that defects can be exposed in advance and the service life of products can be extended. Different brands and different parts have different requirements. Therefore, manufacturers must clarify their own testing standards in the development stage. —— Salt spray concentration, temperature and humidity, and grade determination can not be omitted.

 In the smart home industry, FCC certification stands as an indispensable requirement for all manufacturers.   The Federal Communications Commission (FCC) in the United States established this standard to ensure electronic devices meet stringent requirements regarding electromagnetic compatibility and radio frequency interference.   For smart home products—including smart speakers, lighting systems, and security devices—only through FCC certification can they demonstrate safety and reliability in terms of electromagnetic radiation and signal interference. FCC certification not only determines whether a product can enter the U.S. market, but also serves as a symbol of quality and safety.   It requires manufacturers to conduct a series of professional tests, including electromagnetic interference (EMI) and electromagnetic susceptibility (EMS) evaluations, to ensure stable operation in complex electromagnetic environments. These tests guarantee that the p...

Do you know why some non-metallic materials become brittle, fade or even deform after a long time of use? In fact, it is all caused by ultraviolet light! Long-term exposure to ultraviolet light will quietly change the molecular structure of non-metallic materials, affecting its performance and life. Fluorescent UV testing is very important!  It can simulate the environment of ultraviolet light and help us "predict" the aging degree of materials in advance. Dear manufacturers, this is no small matter!  If the product does not pass this test, it may not be long before there is a problem, and then the brand will be ruined. In addition, the market competition is so fierce now, products that meet the testing standards are the real "hard currency", can win more customers' trust.

 The price difference for RoHS testing of the same product is 10 times. How to choose ROHS testing? Key charging factors: Select the detection range (4 items for basic, 6 items for extended, and full EU set) Product material classification (single material/composite material/special coating) Urgent service requirements (conventional 5 days / urgent 48 hours) Report certification level (general report /CNAS international certification)

 Today I will tell you what the cost of RoHS testing is, after reading it, I am sure you will have a clear idea!  The charging difference mainly depends on three key points: The first is the number of tests, whether it is the basic four items, or the more comprehensive 10 items, or the full set of tests Second, the complexity of sample material, metal, plastic or mixed materials, different materials can be different in detection difficulty The third is whether to have a CNAS certification report, which is the "golden signboard" of the test report. With it, the report will be more authoritative.

 The market is now filled with a wide variety of products, but their quality varies greatly. Drop testing is a crucial step in assessing product quality.  Many manufacturers may not realize that this test is essential. It simulates the potential drop scenarios a product might encounter in real-world use, allowing for early detection of issues, preventing after-sales disputes, and enhancing product competitiveness. Conducting a reliability drop test is not difficult. First, the manufacturer must clarify whether their product standards are based on national, industry, or company standards.  Different standards have varying levels of strictness and focus.  Next, choose a reputable and qualified testing institution. They will develop a detailed test plan based on your product and standards, including parameters such as drop height, frequency, and angle.  During the testing process, the manufacturer can also be involved to monitor the product's performance.
