A quick guide to IP Ratings
What does it stand for?
IP stands for International Protection Code and/or Ingress Protection Code, whatever you choose it means the same thing! The level of protection against solid objects (1st digit) and liquid ingress (2nd digit). The higher the number the higher the protection.
At Extreme Cases you might see the following ratings:
- IP65 - IP rated as "dust tight" and protected against water projected from a nozzle.
- IP66 - IP rated as "dust tight" and protected against heavy seas or powerful jets of water.
- IP 67 - IP rated as "dust tight" and protected against immersion.
- IP 68 - IP rated as "dust tight" and protected against complete, continuous submersion in water.

A quick guide to Fragility Levels
Fragility levels are key in enabling us to make sure we design the right product for your equipment.
Basically we need to establish that if your product was dropped from a great height, what level of protection it would need.
Fragility is often described in terms of ‘G’ value. The more fragile your equipment, the less G’s it will withstand. We need to work out what shocks or foam cushioning would be required to make sure it survives.
Not all the time the fragility level of COT’s equipment is available, so use this table as a rough guide:
| A guide to fragility levels | ||
| Extremely fragile | Missile guidance systems, gyroscopes, precision aligned test instruments | 15-25 G’s |
| Very delicate | X-ray equipment, flight instruments | 25-40 G’s |
| Delicate | Display terminals, printers, test instruments, hard disk drives | 40-60 G’s |
| Moderately delicate | Television receivers, aircraft accessories | 60-85 G’s |
| Moderate rugged | Household appliances | 85-115 G’s |
| Rugged | Mechanical equipment. Machinery | 115 G’s & up |
