Mechanical shock test

Mechanical shock test

Electronic products in the production process, handling process, transportation process, and even the use of time, will be subject to mechanical impact, and mechanical impact test equipment to simulate the impact of these processes to verify the product's ability to withstand impact.

Light performance test

Light performance test

Optical performance is a big index, which is composed of solar transmittance, solar reflectance, solar absorption rate, visible light transmittance, visible light reflectance, total solar blocking rate, ultraviolet blocking rate, shading coefficient, U-value and other small indicators. When light hits paper, plastic, glass, metal and other materials, it shows normal reflection, but the number of reflections is different. Manufacturers of lighting products must ensure that they meet all the performance requirements of their target markets worldwide.

High and low temperature test

High and low temperature test

High/low temperature (storage/operation) test is to simulate the influence of high/low temperature environment on the operation of the product, and is used to evaluate the environmental adaptability and durability of the product. In the field of electrical and electronic, high and low temperature test is a very important test method, which can simulate the working state of electronic equipment under different temperature conditions, evaluate its performance and stability, find its potential problems and solve them, and have the following important significance for ensuring the stable operation of electronic products:

Dust test

Dust test

Dust-proof test grade, IP 1X: external foreign matters with a protection diameter ≥ 50mm shall enter. During the test, a rigid ball with a diameter of 50+0.05mm without handle and protection shall be pushed to any pore of the casing with a force of 50N + 10%. The rigid ball shall not completely enter the casing.

Drop Test

Drop Test

The drop test is divided into package drop and bare metal drop. Packaging drop mainly considers the ability of the product to resist accidental drop impact under the conditions of transportation and storage; bare metal drop mainly considers the ability of the product to resist accidental drop impact during normal use. The package drop may also reflect the ability of the package to protect the product when subjected to a vertical drop.

Uv aging test

Uv aging test

Ultraviolet aging test is also called UV aging test. Ultraviolet aging does not simulate full-spectrum sunlight, but simulates the destructive effect of sunlight. This is achieved by controlling the main radiation of the fluorescent tube in the ultraviolet band of the solar spectrum.

UL9 combustion test

UL9 combustion test

The UL94 flammability test was developed by the U.S. Insurance Industry Laboratory (Underwriters Laboratories Inc.) and has been widely used to determine the flammability of plastics in manufacturing equipment and appliances (but not for materials used for construction purposes).

MSDS Report

MSDS Report

MSDS (Material Safety Data Sheet) is a chemical safety technical manual, which can also be translated as a chemical safety manual or a chemical safety data manual. It is a document used by chemical manufacturers and importers to clarify the physical and chemical characteristics of chemicals (such as PH value, flash point, flammability, reactivity, etc.) and the possible harm to the health of users (such as carcinogenicity, teratogenicity, etc.).

Harmonic flicker test

Harmonic flicker test

Strictly speaking, the harmonic refers to the electric quantity contained in the current whose frequency is an integer multiple of the fundamental wave, and generally refers to the Fourier series decomposition of the periodic non-sinusoidal electric quantity, and the electric quantity generated by the current whose frequency is greater than the fundamental wave frequency.

Disturbance power test

Disturbance power test

Harassment power test is one of the most common EMC tests in the certification of AV products, home appliances and power tools. This paper starts from the test principle of harassment power, discusses the main points of the test, as well as the analysis of the reasons for the failure of the test, and the countermeasures that can be taken. After giving a practical rectification case to illustrate.

Surge test (lightning test)

Surge test (lightning test)

Lightning surge test is a test project of EMS, which mainly tests the immunity of the equipment under test (EUT) to the induced voltage transient generated by lightning. Because during the use of EUT, when lightning strikes, an induced peak voltage may be generated on the power line and signal line, which may cause EUT performance degradation or even damage. The lightning surge test is to simulate and generate a peak voltage through a surge signal generator (lightning surge generator) and couple it to the power line and data line, observe whether EUT can work normally under such a large induction pressure impact.

Electrostatic test

Electrostatic test

Corona discharge is a kind of discharge characterized by corona. When two electrodes in a gas have a shape that causes the electric field on their surface to be significantly larger than the electric field between the two electrodes. Corona discharge will cause electromagnetic interference, which will interfere with aircraft and aerial bombs, causing terminal or failure of communication system and causing accidents.
