How Do We Know the Waterproof Grade of the Venting Membrane?
You may not know about waterproof and breathable membranes. Let's take a look at the waterproof grade introduction of waterproof and breathable membranes! The waterproof level of the waterproof and breathable membrane also reflects the ability of the product to prevent moisture and dust. In a special-use environment, the sealing and waterproof ability of the waterproof and breathable membrane is essential to ensure the safe use and life of the product. For this reason, corresponding waterproof standards have been formulated internationally.
The waterproof grade of the waterproof breathable membrane (the second X indicates)
0: No protection
1: Water droplets will not affect the shell
2: When the shell is tilted to 15 degrees, the water droplets into the shell have no effect
3: Water or rain has no effect on the shell from the 60 degree corner
4: The liquid is splashed into the shell from any direction without harm
5: Rinse with water without any harm
6: Can be used in the cabin environment
7: It can withstand water immersion in a short time (1m)
8: Long time immersion in water under certain pressure
Dustproof level of waterproof and breathable membrane (indicated by an X in front)
0: No protection
1: Prevent the intrusion of large solids
2: Prevent the intrusion of medium-sized solids
3: Prevent small solids from entering and intruding
4: Prevent solid objects larger than 1mm from entering
5: Prevent the accumulation of harmful dust
6: Completely prevent dust from entering
A scale or display instrument is marked as IP65, which means that the waterproof vapor permeable membrane can completely prevent dust from entering and can be washed with water without any harm.
