Standard definition of IP67 waterproofing grade
IP degree is an international standard for measuring the dust and water resistance of equipment. In the two-digit IP code, the first number represents the level of protection against foreign objects, including dust. The second number indicates the waterproof rating of the device. The IP level obtained must be certified and independently tested before it can be shown on the product description.
For the division of IP levels, specific reference materials are as follows:
IP _X: anti-foreign matter and dustproof grade IP0X- without any special protection function.
IP1X- prevent the human body (such as the palm) from accidentally contacting the internal parts of the electrical appliance, and prevent the external objects of large size (diameter greater than 5mm) from entering.
IP2X- Prevent human fingers from touching the internal parts of the appliance, and prevent the invasion of external objects of medium size (diameter greater than 12.5mm).
IP3X- prevent tools, wires and similar small objects with diameter or thickness greater than 2.5mm from intruding and touching the internal parts of the electrical appliance.
IP4X- prevent tools, wires and similar small objects with diameter or thickness greater than 1CM from intruding and touching the internal parts of the electrical appliance.
IP5X- can partially prevent the invasion of dust (will not produce harmful deposits), although can not completely prevent the invasion of dust, but the amount of dust invasion will not affect the normal operation of the electrical appliances.
IP6X- completely sealed to prevent the invasion of foreign objects and dust.
IP X_ : Waterproof grade IPX0- without any special protection function.
IPx1 - Drops of water falling vertically (such as condensed water) will not cause damage to electrical appliances.
IPX2- The tilt Angle of the device is within 15 degrees of the general position to avoid water droplets entering.
IPX3- Rain proof or prevent water sprayed in the direction of vertical Angle less than 60 degrees from invading the electrical appliances and causing damage.
IPX4- prevent the water from all directions to invade the electrical equipment and cause damage.
IPX5- can resist the water column of the low pressure spray gun for at least 3 minutes.
IPX6- can resist water column of high pressure spray gun for at least 3 minutes.
IPX7- can withstand up to 30 minutes of immersion in water up to 1 meter deep.
IPX8- can withstand continuous immersion in water more than 1 meter deep, the standard of this grade will have a certain range of fluctuations.
To sum up, the waterproof level of writing is "IP + (figure A) + B (digital), digital A representative dust levels, and digital B on behalf of the waterproof grade, IP67 level dust level 6, waterproof grade is 7, the number" 7 "representatives can bubble water in A short time, but we can understand for your mobile phone fell into the water, fish tank, bath, such as low water, quickly take out is not A problem, IP67 has enough for everyday use.
Under normal circumstances, LED waterproof power supply with IP65 grade can meet the general needs, Yansuo Da LED waterproof power supply are in line with the IP67 grade standard.
