The IP Code Breakdown
The initial IP designation will be used for all IP codes.
- The first digit is used to designate the amount of protection given against particle protection. This number will fall between 0-6
- The second digit is used to designate the protection against liquid ingress. This number ranges from 0-9
First digit: Solid Particle Protection
0 - No protection against any ingress of objects.
1 - Any large surface of the body, such as the back of the hand
2 - Fingers and smaller objects
3 - Tooling, thick wires
4 - Most wires, small screws, insects
5 - Dust protected: Ingress of dust is not completely prevented, but must stop large amounts entering
6 - Dust Tight: No ingress of dust, complete protection against against dust and particles.
Second digit: Liquid Ingress Protection
0 - No protection against water ingress
1 - Dripping water will have no harmful effect when unit is mounted upright
2 - Dripping water will have no impact when unit is mounted on angle up to 15 degrees
3 - Spraying Water: Water falling as a spray at any angle up to 60 degrees
4 - Water splashing against enclosure from any direction
5 - Water from a nozzle, in any direction
6 - Water from powerful water jets in any direction
7 - Immersion in water up to 1m
8 - Equipment is suitable for continuous submersion in water at depths greater than 1m for specified time
9K - protected against close range high pressure, high temperature spray downs
So what is an IP68 Enclosure?
An enclosure that has been rated at IP68, will have complete protection from any ingress of dust particles and will also be protected against water ingress when submerged continuously at depths of water greater than 1 meter. The depth to which it can be submerged will be as per the manufacturers specifications.
Common Products with Ingress Protection
It is common practice for consumer goods to have an ingress protection these days. Most common is mobile phones, tablets and cameras to have a level of IP protection. It is now possible to buy a smartphone which is waterproof and dust proof. IP ratings can be found on a large range of consumer goods these days thanks to advancements in technology.
Big industry, Big Requirements and Big Ratings
There are thousands of different industries that require products and parts to have high IP ratings to ensure protection against the elements. One of the largest areas of use is from electrical contractors doing installations within harsh environments. There is a large demand from electrical contractors to have suitable enclosures to protect hardware that is at risk of failure from contamination of water and dust. IP68 enclosures will be used widely throughout heavy industry, especially within oil and gas exploration and refinement. IP68 enclosures may also be able to provide an extra level of safety within dangerous environments by reducing the likelihood of equipment failure. In workplaces where equipment failure and unscheduled shutdowns will result in enormous profit losses, it is easy to see why reliable IP68 enclosures are so important.
Enclosures: Examples and Applications
There are a variety of different enclosures on the market made from a range of materials. IP68 enclosures can be made from plastics and polymers, fibreglass all the way through to 316 stainless steel. Consideration to your desired application will determine which IP68 enclosure will suit your needs.
