IP Enclosure Ratings & Standards
IP Ratings For Enclosures
The Ingress Protection (IP) rating indicates how resistant a gadget is to solids and water. The international standard EN 60529 is used to calculate IP ratings.
The term "intrusion" in the context of an IP rating has three definitions: IP codes indicate the amount of protection provided to users (hands, fingers, etc.) by mechanical or electrical elements; the degree of protection provided by an enclosure to those critical components against dust, filth, and other destructive foreign bodies; and the overall resistance to moisture.
Why have an IP rating system?
The purpose of a global IP rating system is to provide purchasers and users with confidence in the safety of using particular electrical or mechanical items in specified environments and applications.
Unlike more ambiguous marketing words like 'waterproof', which may not always provide a clear explanation of exactly where and to what degree an object can withstand moisture infiltration, an IP rating is intended to provide a far more particular account.
As we'll learn later in this tutorial, each digit in an IP rating gives specific information about the amount of protection/resistance that the item in question may be anticipated to provide.
Types of IP rated Enclosure Products
There are various IP-rated goods available on the market. The standardization of these codes allows buyers and users to acquire a clear knowledge of each product's capabilities and limits in various circumstances.
In this part, we'll take a closer look at some of the most common IP ratings seen on the vast majority of ordinary items.
IP Enclosure Ratings Chart
بروتوكول الإنترنت | Description |
---|---|
IP44 | Protection for the enclosed equipment from the entry of solid particles with a diameter greater than 1mm into the enclosure. |
IP54 | Commonly used as traffic control cabinets because of their ability to protect electrical equipment from splashing water or rain conditions. |
IP55 | Weather-resistant enclosures that include a degree of protection from windblown dust and ingress of water. |
IP56 | Designed very similar to NEMA 3 enclosures, however, 3R enclosures can be ventilated. |
IP57 | Often called rain tight enclosures due to their excellent weather resistance. |
IP65 | Generally manufactured using 304 & 316 stainless steel due to its protection from corrosive materials. |
IP66 | Dust tight enclosures that are constructed without punch-outs. |
IP67 | Protecting against water damage during a temporary 30-minute immersion at a depth of between 15cm and 1m. |
IP68 | When submerged in up to 1.5m of water for 30 minutes, it protects against water damage. |
IP Enclosure Ratings Guide
The IP ratings table below explains what each digit in a conventional IP code indicates. This ingress protection chart will help you understand the precise threats and scenarios that a certain item's mechanical or electrical components should be protected against, as well as how much protection is required in what types of environments.
- First digit - protection against foreign bodies and particle ingress:
- Second digit - protection against moisture ingress:
First digit | Intrusion protection | Second digit | Moisture protection |
---|---|---|---|
0 | No protection. | 0 | No protection. |
1 | Protected against solid objects over 50mm, e.g. accidental touch by hands. | 1 | Protected against vertically falling drops of water, e.g. condensation. |
2 | Protected against solid objects over 12mm, e.g. fingers. | 2 | Protected against direct sprays of water up to 15 degrees from the vertical. |
3 | Protected against solid objects over 2.5mm, e.g. tools & wires. | 3 | Protected against direct sprays of water up to 60 degrees from the vertical. |
4 | Protected against solid objects over 1mm, e.g. wires & nails. | 4 | Protected against water splashed from all directions, limited ingress permitted. |
5 | Protected against dust limited ingress, no harmful deposits. | 5 | Protected against low pressure jets of water from all directions, limited ingress permitted. |
6 | Totally protected against dust. | 6 | Protected against strong jets of water, e.g. on ships deck, limited ingress permitted. |
n/a | n/a | 7 | Protected against the effects of temporary immersion between 15cm and 1m. Duration of test 30 minutes |
n/a | n/a | 8 | Protected against long periods of immersion under pressure |
