One of the specifications installers often see are the IP and IK protection ratings. These are indicators of how ‘protected’ the CDVI product is from various elements. Most often, you will see these technicalities presented as “weather resistant” or “vandal resistant.” But what do these acronyms and the numbers next to them mean?

 

What is an IP rating?

The IP or "Ingress Protection" ratings are an industry-recognised system, created by the International Electrotechnical Commission (IEC 60529) to determine the different degrees of protection of the enclosures of electrical and electronic equipment against external elements. In this case, the degree of protection IP indicates the level of resistance to solid agents (dirt/dust) and moisture (drips, sprays, submersion etc.). 

The degree of protection IP always consists of two numbers. The first digit refers to the level of protection against solids, while the second digit indicates the level of resistance to water. The first digit runs on a scale from 0-6, while the second goes up to 8. Therefore, the lowest possible degree of protection is IP00 and the highest is IP68.

In the following table, find a summary of what each rating really means.

LEVEL	First digit (Entrance of solid agents)	Second digit (Entrance of water)
0	No protection.	No protection.
1	Protected against solids objects over 50mm (e.g. accidental touch by hands	No water should enter when it falls from 200mm in height from the equipment, for 10 minutes (at a rate of 3-5mm³ per minute)
2	Protected against solids objects over 12mm (e.g. fingers)	Protected against direct sprays up to 15o from the vertical.
3	Protected against solids objects over 2.5mm (e.g. tools and wires).	Protected against direct sprays up to 60o from the vertical, at an average of 11 litres per minute and at a pressure of 800-100 kN / m² for a time not less than 5 minutes.
4	Protected against solids objects over 1mm (e.g. tools, wires and small wires.	Protected against sprays from all directions, at an average of 10 litres per minute and at a pressure of 800-100 kN / m² for a time not less than 5 minutes - limited ingress permitted.
5	Protected against dust - limited ingress (no harmful deposit)	Jetted water (from any angle) must not enter by means of a 6.3 mm diameter nozzle, at an average of 12.5 litres per minute and at a pressure of 30 kN / m² for a time not less than 3 minutes and at a distance not less than 3 meters - limited ingress permitted.
6	Completely protected against the entrance of dust.	Jetted water (from any angle) must not enter by means of a nozzle of 12.5 mm in diameter, an average of 100 litres per minute and a pressure 100 kN / m² for a time not less than 3 minutes and at a distance that is not less than 3 meters e.g. for use on ship decks - limited ingress permitted.
7		The equipment must withstand without any filtration the complete immersion between 15cm and 1m for 30 minutes.
8		Protected against long periods of immersion under pressure.

 

In summary, we can say that the products that have an IP degree of protection IP20, IP25 or IP33 are meant to be installed indoors. On the other hand, products like our K2 Encrypted Readers, CDV-DDP digital multiway video door station and self-contained keypads with protection IP65, IP64 and IP54 are designed for outdoor installation. 

 

What is an IK rating?

IK or “Impact Protection” (the K is from “Kinetic” to differentiate from IP rating). It is defined in international standards and indicates protection against mechanical impact. Just like IP protection, this code is governed by an international standard (IEC 62262), so that you can make comparisons between different products. In this case, this grade indicates the mechanical resistance to harmful impacts that could damage a product. 

The IK grade varies from 0 (minimum resistance) to 10 (maximum resistance). For example, our SOLAR, NANO, and STAR readers are all IK10 rated!

In the table at the bottom, you can see in more detail the different IK degree values and the energy of impact that the product can support.

Not all impacts come from criminal intentions. Flying debris can also present problems for specific products. Additionally, storms tend to toss around all manner of objects. This is where both the IP and IK numbers come into play, as you want a product that will survive surging water, but also anything picked up by the wind.

Ultimately, IP/IK is intended to help you understand the overall durability of a product. If you just have a set-up indoors, you probably do not need a high IP/IK rating. However, if you are looking for outdoor solution, where both natural and criminal risks are present, then you should consider a product with higher IP/IK standards.

 

CDVI’s Range

The majority of our products that need to be mounted outdoors are rated IP54 or above!
