I/O shield
The is also known as a connection cover or ATX-cover. It is a piece of plate which is secured to the rear of a PC housing and integrates the I/O connections on the motherboard precisely into the housing. The aims of the are to minimise the dust that gets into the interior of the computer and to create an electromagnetic shield for the housing. An is required if several USB devices are to be connected since otherwise interferences may occur
IP
Electrical and electronic components are often exposed to coarse ambient conditions (dirt, dust, moisture, etc.). The protection classes describe the extent to which a component may be exposed to these ambient conditions without suffering damage or posing a safety risk. protection classes to DIN 40050 take the form IPxx. The first digit denotes the protection level against foreign bodies and contact whilst the second digit denotes the protection level against contact with water. The following is a list of the protection classes to VDE 0710 DIN 40050:
First digit – protection level against the ingress of foreign bodies:
- 0: No protection
- 1: Protection against the ingress of solid foreign bodies with a diameter over 50 mm
- 2: Protection against the ingress of solid foreign bodies with a diameter over 12.5 mm
- 3: Protection against the ingress of solid foreign bodies with a diameter over 2.5 mm
- 4: Protection against the ingress of solid foreign bodies with a diameter over 1 mm
- 5: Limited protection against dust ingress 6: Total protection against dust ingress
Second digit – protection level against water:
- 0: No protection
- 1: Protected against vertically falling drops of water or condensation
- 2: Protected against vertically falling drops of water if the housing is tilted at an angle of up to 15°
- 3: Protected against vertically falling drops of water if the housing is tilted at an angle of up to 60°
- 4: Protected against water sprayed from all directions
- 5: Protected against low pressure water jets from any direction
- 6: Protected against high pressure water jets from any direction
- 7: Protected against short periods of immersion in water
- 8: Protected against long, durable periods of immersion in water. An additional digit denotes the immersion depth in metres.
ISO 14001
was introduced in 1996 and is an environmental management system in which environmental protection is systematically set out in a management system.
