In the world of electronics, outdoor equipment, industrial enclosures, and consumer devices, IP Rating remains one of the most searched technical keywords. If you’ve ever wondered “What is an IP rating? What exactly is an Ingress Protection Rating?”, this comprehensive guide breaks it down with clear explanations, charts, and real-world applications.


IP Protection Standards Overview
IP Rating (Ingress Protection Rating) is defined by the international standard IEC 60529 (also known as BS EN 60529 or IP Code 60529). It measures how well an enclosure protects internal components against solid objects (dust, fingers, tools) and liquids (water).
The code format is IP followed by two digits (e.g., IP65, IP67, IP68, IP69K):
- First digit (0-6): Protection against solids and dust
- Second digit (0-9): Protection against water


IP Rating Protection Level Chart
| First Digit (Solids) | Protection Level | Second Digit (Liquids) | Protection Level |
|---|---|---|---|
| 0 | No protection | 0 | No protection |
| 1 | >50mm objects (hand) | 1 | Vertical dripping water |
| 2 | >12.5mm objects (finger) | 2 | 15° angled dripping water |
| 3 | >2.5mm objects (tools) | 3 | Spraying water at 60° |
| 4 | >1mm objects | 4 | Splashing water from any direction |
| 5 | Dust protected | 5 | IPX5 IPX6 Water Jet Protection |
| 6 | IP6X Dust tight | 6 | Powerful water jets |
| – | – | 7 | Temporary immersion (1m, 30min) |
| – | – | 8 | IP68 Rating Continuous Immersion |
| – | – | 9K | IP69K High Temperature Water Jet |
IP65 vs IP67 vs IP68 Difference & Real-World Applications
- IP65: Dust tight + water jets → Ideal for general outdoor equipment
- IP67: Dust tight + temporary immersion → Common for smartphones and portable devices
- IP68: Dust tight + continuous submersion → Used in underwater instruments and rugged electronics
- Highest Ingress Protection Rating IP69K: Withstands high-pressure, high-temperature water jets → Perfect for food processing, automotive, and marine applications
