IP65 Certification Introduction(IP65/IP66/IP67/IP68 Protection class)

Prime number (anti-hard object) Definition Minor number (anti-liquid) Definition
IP65 authentication Dust, but allows a small amount into the (harmless accumulation)

IP65 authentication

Prevent from all sides of low-pressure water spray, but allow a few enter

IP65 authentication

Completely dustproof

IP65 authentication

Prevent powerful spout, such as planking, but allowing a few enter used
   

IP65 authentication

15 centimeters to within one metre of SRM can waterproof, temporarily during the testing for 30 minutes
   

IP65 authentication

But long-term bear heavy pressure

IP protection class (dust and water) is defined

IPxxIP65、IP66、IP67、IP68

Dust level (the first X that)

0: No protection
1: to prevent the invasion of large solid
2: to prevent the intrusion of solid medium-sized
3: to prevent intrusion into the small solid
4: Prevention of solid objects greater than 1mm into
5: to prevent the accumulation of harmful dust
6: completely prevent dust entering

Waterproof Grade (the second X that)

1: No water droplets trickle-down effect to the shell
2: When the shell tilted to 15 degrees, dropping to the shell has no effect on water droplets
3: water or rain water from 60 degrees to the shell on the corner of no effect
4: Liquid splashed from any direction without damage to the outer shell of
5: wash with water without any harm to
6: can be used for the cabin environment
7: flooding tolerance in a short time (1m)
8: in the long immersion under pressure

IP 65 technology
Test Method / Specification
Testing method: Reference to the international electrotechnical commission (IEC) 60529 2.1 version: 2001-2002 - IP 65
1. To prevent contact dangerous parts of test:
Testing method: IEC 60529 2.1 version: 2001-2002 - IP6X
  1 mm in diameter, the test length of 100 mm or embedded with wire advancing any holes on the chassis, and "IEC 60529 2.1 edition :2001-2002, " the strength specified in Table 6, testing whether the exposure wire The risk of power to the chassis components.
Test intensity: 1 N ±10%
2. Prevent hard eyewinker test:
Testing method: IEC 60529 2.1 version: 2001-2002 - IP6X (dustproof testing)
Dust type: Talcum powder
Dust capacity: 2kg
Machine room size 1m3
Maximum pressure: -20 mbar
During the test: 8 hours
3. Waterproof test:
Testing method: Reference IEC 60529 2.1 version: 2001-2002 - IPX5
Waterproof test:  
Test mode: With a test specification specified standard test nozzle, from all feasible direction of water cabinet.
Nozzle diameter: 6.3mm
Spray speed: 12.5 per minute± 5%
