Acoustic test

Acoustic testing looks at the movement of sound, noise, and vibration. Having an acoustically rated product means that it can help diminish sound activity from outside sources.

EMI test

EMI is electromagnetic energy that affects the functioning of an electronic device. Sources of EMI can sometimes be naturally occurring environmental events, such as electrical storms and solar radiation; but often, the EMI source is another electronic device or electrical system.

While EMI is generated from any electronic device, certain equipment and components are more likely to create disturbances than others. Additionally, the design of the product can affect EMI.
FCC Part 15 rules define limits for unlicensed radio frequency interference that can be produced by consumer electronics and other devices. The purpose of the EMI test is to ensure that any emission from the device is below the relevant limits defined for that type of device.
As you can see from the video, the system performance is stable in the period of 30-1000MHz; the test results come from this frequency segment, and the device passes testing. With this result, we’ve met another milestone in designing the world’s best motorcycle helmet

Salt spray test

The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.
