  Salt spray test is a commonly used environmental simulation accelerated corrosion test method, which is mainly used to evaluate the corrosion resistance of metal materials and their coatings, coatings, paints and other surface treatment processes. This test accelerates the corrosion process on the material surface by simulating the corrosion conditions in the Marine environment or industrial atmosphere, in order to assess the corrosion resistance of the material in a short period of time. Main test items: salt spray test (neutral, acetic acid, copper accelerated acetic acid), cyclic corrosion test, condensate water, water mist, etc.

  SRRC Certification is a mandatory certification of radio transmission equipment in China to ensure its spectrum use compliance and avoid interference. Products required for certification include: 1. Wireless communication equipment: mobile phones, routers, Bluetooth headset, etc. 2. Wireless remote control: toys, drones. 3. Wireless microphone and amplification system. 4. Radio navigation equipment. 5. Radio intercom. 6. Radio broadcasting and transmitting equipment. 7. Other radio-spectrum equipment. It shall not be sold and used in China without SRRC certification.

Suitable for external lighting, signal devices and automotive lamp shell protection, can provide realistic analog electronic products and their components during the transportation and use of the spray test may be subjected to water and other environment, to detect the waterproof performance of various products. Common operation mode 1.Preparation: First, select a test device that can simulate the real rainfall conditions. A spraying system or spray device can be used to ensure a uniform and continuous flow of rainwater. 2.Sample preparation: Cut the material to be tested into the appropriate size, usually square or rectangular. Ensure that the edges of the sample are flat, with no obvious defects. 3.Install the samples: attach the sample to the device to ensure full level and withstand rain. 4.Adjust test parameters: adjust the operating parameters of the shower, such as flow and spray Angle. 5. Experimental: turn on the shower and start the experiment. Usually the experiment lasts fo...

The vibration test methods can be divided into sinusoidal vibration and random vibration: Sinusoidal vibration is often used in the laboratory test method, to simulate rotation, pulsation, shock (in ships, aircraft, vehicle, space aircraft) on the vibration and the resonance frequency analysis of product structure and little note to pick up card is given priority to, it is divided into two kinds of sweep vibration and fixed frequency vibration, the harsh degree depends on the frequency range, loss amplitude, test duration. Random vibration is assessed as the seismic resistance strength of the overall structure of the fire module product and the delivery environment in the packaging state, and its severity depends on the frequency range, GRMS, test duration and axial direction.

1. Electromagnetic compatibility (EMC): harassment power, radiation harassment, terminal harassment voltage, electrostatic discharge immunity, electromagnetic radiation immunity, conduction immunity, etc. 2, low voltage part (LVD): harmonic current, voltage fluctuation and flicker, current intensity, instantaneous voltage, etc.

The specific items of the food contact material testing of the juicer are as follows: 1. Stainless steel knife head test items: Total chromium 2. PP material test items: Specific gravity Melting point (only for PP) n-hexane extractives Xylene extractives
