What is IP Rating?
IP Rating stands for Ingress Protection Rating. A standardized code that defines the level of protection a device offers against the intrusion of solid particles and liquids.
What is IP Rating (Ingress Protection)?
An IP rating, or Ingress Protection rating, defines the level of defense a device offers against solids like dust and liquids such as water. This international standard (IEC 60529) helps users understand how well equipment performs in challenging environments.
How to read an IP rating?
The rating typically appears as IP followed by two digits. The first digit indicates protection against solids (like dust and sand), while the second digit refers to resistance against liquids (water= rain, jets, immersion). For example, IP67 means a device that is completely dust-tight and can withstand submersion in water up to 1 meter for 30 minutes. IP68 offers even higher water resistance.
TOUGHBOOK IP Ratings at a Glance
In rugged computing, IP ratings are critical. They ensure devices can operate reliably in field conditions, from construction sites to emergency response scenarios. Our TOUGHBOOK lineup includes a range of IP-rated models built to perform where others can’t:
• TOUGHBOOK 40 – IP66: sealed against dust, powerful water jets
• TOUGHBOOK 33 & G2 – IP65: dust-tight, protected against water jets
• TOUGHBOOK 55 – IP53: limited dust ingress, protected against light sprays
An IP rating tells you how well a device is protected from dust and water. The higher the numbers, the stronger the protection, essential for rugged environments where TOUGHBOOK devices are built to thrive.
IP Rating Chart - Ingress Protecion Levels
First Digit: Protection against solids (Dust, Particles)
| Digit | Protection Level | Description |
| 0 | No protection | No protection contacts or objects |
| 1 | > 50 mm | Protected against large surfaces |
| 2 | >12.5 mm | Protected against fingers or similar objects |
| 3 | > 2.5 mm | Protected against tools, thick wires |
| 4 | > 1 mm | Protected against most wires, screws |
| 5 | Dust-protected | Limited ingress of dust, no harmful deposits |
| 6 | Dust-tight | Complete protection against dust ingress |
Second Digit: Protection against liquids (water)
| Digit | Protection Level | Description |
| 0 | No protections | No protection against water |
| 1 | Dripping water | Vertically falling drops |
| 2 | Dripping water (tilted 15°) | Protection when tilted |
| 3 | Spraying water | Up to 60° from vertical |
| 4 | Splalshing water | From any direction |
| 5 | Water jets | Low-pressure jets from any direction |
| 6 | Powerful water jets | High-pressure jets |
| 7 | Immersion up to 1 meter | Up to 30 minutes underwater |
| 8 | Continuous immersion | Beyond 1 meter (manufactured-defined) |
| 9 | High-pressure, high temperature jets | Used in industrial cleaning |

IP Rating stands for Ingress Protection Rating. It’s a standardized measure defined by IEC 60529 that indicates how well a device is protected against solid particles (like dust) and liquids (like water). The rating consists of two digits:
- First digit: Protection against solids (0–6)
- Second digit: Protection against liquids (0–9)
A device is considered fully waterproof if it has an IP rating of IP67 or higher:
- IP67: Protected against dust (6) and immersion in water up to 1 meter for 30 minutes (7)
- IP68: Protected against dust and continuous immersion in water beyond 1 meter (depth and duration defined by manufacturer)
- IP69: Protected against high-pressure, high-temperature water jets
For TOUGHBOOKs, models like the TOUGHBOOK 40 (IP66) and TOUGHBOOK G2 (IP65) are water-resistant, but not fully waterproof for immersion.
Check the official datasheet or product brochure
Each TOUGHBOOK model (e.g., G2, 40, 55, 33) lists its IP rating under technical specifications.
- Look at the label on the device
Some models have the IP rating printed near the battery or on the chassis.
